Page 9: Main Features
1 Main Features Vertical Axis This section explains how to configure the signal input settings and the amplitude-direction display settings. The items that can be set vary depending on the installed modules. The channel menu that corresponds to the key you pressed (CH1 to CH16) appears.
Page 10: Horizontal Axis (Time Axis)
1 Main Features Input Coupling You can change the input coupling setting to match the signal that you are measuring. By changing the setting, you can choose how the vertical-axis (voltage-axis) control circuit is coupled to the input signal. The following types of input coupling are available: DC, AC, GND, TC, DC-RMS, AC-RMS, ACCEL, and OFF.
Page 11: Trigger
1 Main Features Relationship between the Time Axis Setting, Record Length, and Sample Rate If you change the time axis setting, the sample rate and the acquisition-memory record length also change. For details, see appendix 1 in the Getting Started Guide, IM DL850E-03EN. Sample Rate If you change the time axis setting, the sample rate also changes.
Page 12: Waveform Acquisition
1 Main Features OR Trigger The DL850E/DL850EV triggers on the OR of multiple trigger source edges. AND Trigger The DL850E/DL850EV triggers on the AND of multiple trigger source conditions. The DL850E/DL850EV triggers when all the specified conditions are met at a single point. Period Trigger The DL850E/DL850EV triggers on a specified period of occurrence of state condition B.
Page 13 1 Main Features Record Length Record length refers to the number of data points that are stored to the acquisition memory for each channel. Display record length refers to the data points from the data stored in the acquisition memory that are displayed on the screen.
Page 14: Waveform Display
1 Main Features Waveform Display The DL850E /DL850EV has a main window for displaying normal time-domain waveforms, zoom windows for displaying zoomed time-axis waveforms, and X-Y windows for displaying X-Y waveforms. In addition, you can split screens and change the sizes of waveform display areas so that waveforms and measured values are easier to see and display an FFT window that shows the results of FFT analysis.
Page 15 1 Main Features There are three statistical processing methods: • Normal statistical processing While acquiring waveforms, the DL850E/DL850EV measures the measurement items and calculates the statistics of the waveforms that it has acquired so far. • Cyclic statistical processing (measurement and statistical processing are performed for each period) The DL850E/DL850EV divides the waveform into periods starting at the left side of the screen (the oldest waveform) and moving to the right side of the screen, measures the selected measurement items within each period, and performs statistical processing on the measurement items.
Page 16 1 Main Features Notes about Using the 16-CH Voltage Input Module (720220), Notes about Using the 16-CH Temperature/Voltage Input Module (720221) Notes about Using the 16-CH Voltage Input Module (720220) While normal voltage input modules have two main channels for analog input, the 16-CH voltage input module has 16 sub channels for analog input.
Page 17: Temperature/Voltage Input Module (720221)
1 Main Features • Because the waveform data stored in the acquisition memory is used to display waveforms on the screen, the data of all sub channels is displayed as if though it were sampled at the same timing. • The following operations are performed on the waveform data stored in the acquisition memory: waveform zooming, cursor measurement, the automated measurement of waveform parameters, computation, FFT, waveform searches, and the loading and saving of waveform data.
Page 18: Vertical Axis
2 Vertical Axis This section explains how to configure the signal input settings and the amplitude-direction display settings. The items that can be set vary depending on the installed modules. Input Settings CH1 to CH16 The channel menu that corresponds to the key you pressed appears. You can set the various vertical axis settings for each channel.
Page 19: Voltage Measurement
2 Vertical Axis Voltage Measurement For voltage measurement, the items that have to be set for each input signal (CH1 to CH16) include vertical scales, the vertical positions, input coupling, probe attenuation, the bandwidth limit, the zoom method, the offset, waveform inversion, trace settings, and linear scaling.
Page 20: Vertical Scale (Scale Knob)
2 Vertical Axis Vertical Scale (SCALE knob) Voltage Scale Setting The vertical scale is used to adjust the displayed waveform amplitude so that you can easily view signals. Set the vertical scale by voltage per grid square (V/div) or current per grid square (A/div) on the screen. Use the SCALE knob to set the vertical scale for each channel and sub channel.
Page 21 2 Vertical Axis Measurement and Display Ranges The measurement range of the DL850E/DL850EV is ±10 div, with 0 V in the center (the absolute width, or span, is 20 div). The default display-range setting is ±5 div (the span is 10 div). Using the features listed below, you can move and scale the displayed waveform so that parts of it that were outside of the display range are displayed.
Page 22: Waveform Vertical Position (Vertical Position Knob)
2 Vertical Axis Waveform Vertical Position (Vertical POSITION knob) The DL850E/DL850EV can display the waveforms of the main analog-input channels, the waveforms of the sub analog-input channels, and computed waveforms. Because the DL850E/DL850EV can display so many waveforms, the waveforms may overlap and be difficult to view. If this happens, you can adjust the vertical display position to make waveforms easier to view (vertical position).
Page 23: Input Coupling (Coupling)
2 Vertical Axis Input Coupling (Coupling) It is easier to measure the amplitude of an AC signal if you remove its DC component. On the other hand, there are times when you want to measure the ground level or observe the entire signal, including both the DC and AC components.
Page 24: Probe Attenuation And Current-To-Voltage Conversion Ratio (Probe)
The attenuation settings available on the DL850E/DL850EV are 1:1, 10:1, 100:1, 1000:1, 10 A:1 V , and 100 A:1 . If you use a probe other than one of the separately sold optional accessories provided by Yokogawa, set the attenuation ratio in accordance with that probe.
Page 25: Bandwidth (Bandwidth)
2 Vertical Axis Bandwidth (Bandwidth) You can specify a bandwidth limit for each module. You can use bandwidth limits to observe input signal waveforms with their noise components removed. Normal Bandwidth Limits You can remove high-frequency components from the input signal. The bandwidth limits vary as shown below depending on the input module.
Page 26: Zoom Method (V Scale)
2 Vertical Axis Zoom Method (V Scale) You can choose the method for zooming the waveform vertically. • DIV: The waveform is zoomed by a set magnification. • SPAN: The waveform is zoomed to fit within specified upper and lower display limits. Zooming by Setting a Magnification (V Zoom) When V Scale is set to DIV, you can set the vertical magnification and enlarge or reduce the waveform along the vertical axis.
Page 27 2 Vertical Axis Zooming by Setting Upper and Lower Display Limits (Upper/Lower) When V Scale is set to SPAN, you can set the upper and lower vertical limits and enlarge or reduce the waveform along the vertical axis. By setting the appropriate upper and lower limits for the displayed waveform, you can zoom in vertically on the area of the waveform that you want to observe.
Page 28: Offset (Offset)
2 Vertical Axis Offset (Offset) By adding an offset, you can move the waveform to a vertical position that is easier to see. For example, when measuring a signal with a fixed voltage component, you can use the offset to cancel out the fixed voltage and measure the signal changes at a higher voltage sensitivity.
Page 29: Dc Offset Cancel (Dc Offset Cancel)
2 Vertical Axis DC Offset Cancel (DC Offset Cancel) This function can be used to determine cursor measurement values, automatically measured values of waveform parameters, and computed values by assuming the DC signal voltage measured during offset adjustment to be 0 V. The adjustment range is ±30% of the measurement range.

Inverted Waveform Display (Invert) When measuring voltage and strain, you can invert the waveform display around the vertical position. Normal display Inverted display Vertical position...
Page 31: Linear Scaling (Linear Scale)
2 Vertical Axis Linear Scaling (Linear Scale) Linear scaling is a function that converts measured values into physical values and reads them directly. When you measure voltage (current), strain, or frequency (revolutions, periods, duty ratios, power supply frequencies, pulse widths, pulse integration, velocities), you can choose from one of two linear scaling methods: AX + B or P1-P2.
Page 32 2 Vertical Axis Display Type (Display Type) When you measure voltage using a voltage module or measure strain using a strain module, you can display the linearly scaled results using one of the following two methods. Exponent: Values are displayed in exponential notation. Floating: Values are displayed as decimal numbers.
Page 33: Rms Measurement
2 Vertical Axis RMS Measurement When the selected channel belongs to the 701267 (HV (with RMS)), you can observe the RMS values of the input signal. AC-RMS Use this setting when you only want to observe the RMS values of the input signal without the DC component. Example When you measure the RMS values of a 2 Vpeak sine wave, an approximately 1.4 VDC signal appears, as shown in the figure on the right.

Page 94: Horizontal Axis
3 Horizontal Axis Time Axis Setting (TIME/DIV) When the internal clock is being used, the time axis scale is set as a length of time per grid division (1 div). The time axis scale can be set within the following ranges: 100 ns/div to 30 s/div, 1 min/div to 30 min/div, 1 hour/div to 12 hour/div, and 1 day/div to 20 day/div.
Page 95 3 Horizontal Axis How the Time Axis Relates to the Display of the Waveform There are 10 div along the time axis, and 1001 points (logical number of points, not the dots on the screen) are used to draw the waveforms. Therefore, if the display record length is exactly 1 kpoint (the number of acquired data points is 1001), the waveform is displayed using 1001 points.
Page 96 3 Horizontal Axis Sample Rate If you change the time axis setting, the sample rate also changes. The sample rate is the number of samples- per-second (S/s). * If the sample rate is comparatively low with respect to the input signal frequency, the harmonics contained in the signal are lost.
Page 97: Triggering
4 Triggering A trigger is a cue used to display the waveform on the screen. A trigger occurs when the specified trigger condition is met, and a waveform is displayed on the screen. Trigger Mode (MODE) The trigger mode determines the conditions for updating the displayed waveforms. There are six trigger modes. Auto Mode (Auto) If the trigger conditions are met before an approximately 50 ms timeout, the DL850E/DL850EV updates the displayed waveforms on each trigger occurrence.
Page 98: Trigger Types (Type)
4 Triggering Trigger Types (Type) The following trigger types are available. Simple (Simple) • Simple trigger: Simply triggers on a trigger source edge. In addition to using the signals (analog signals and logic signals) applied to the modules installed in the slots as trigger sources, you can also use the time, an external signal (the signal applied to the TRIG IN terminal), or the power line signal as a trigger source.
Page 99: Simple Trigger (Simple)
4 Triggering Simple Trigger (Simple) The DL850E/DL850EV triggers on trigger source edges (rising or falling edges). Edge refers to a point where the trigger source passes through the trigger level.

4 Triggering Trigger Slope (Slope) Slope refers to the movement of the signal from a low level to a high level (rising edge) or from a high level to a low level (falling edge). When a slope is used as one of the trigger conditions, it is called a trigger slope. The following trigger slope settings are available for triggering the DL850E/DL850EV.
Page 102: Trigger Position (Position)
4 Triggering Trigger Position (Position) When you move the trigger position, the ratio of the displayed data before the trigger point (the pre-trigger section) to the data after the trigger point (the post-trigger point) changes. When the trigger delay is 0 s, the trigger point and trigger positions coincide.

Page 114: Waveform Acquisition
5 Waveform Acquisition Based on the data that has been stored in the acquisition memory, the DL850E/DL850EV performs various operations, such as displaying waveforms on the screen, computing, measuring cursors, and automatically measuring waveform parameters. This chapter explains how to set the number of data points to store in the acquisition memory (the record length), how to enable or disable the sample data averaging feature, and so on.
Page 115 5 Waveform Acquisition Acquisition Mode (Acquisition Mode) You can set the acquisition mode to one of the options below. Normal Mode (Normal) Displays waveforms without processing the sampled data. Envelope Mode (Envelope) The DL850E/DL850EV determines the maximum and minimum values among the data sampled at the maximum sample rate for each module at a time interval that is twice the sampling period (the inverse of the sample rate) of Normal mode, saves the values as pairs in the acquisition memory, and uses the saved value pairs to display the waveforms.
Page 116 5 Waveform Acquisition Averaging Mode (Average) The DL850E/DL850EV acquires waveforms multiple times, averages the same time points relative to the trigger point, saves them in the acquisition memory, and uses them to display averaged waveforms. Averaging mode is useful when you want to remove random noise from waveforms. The averaging method varies depending on the acquisition count.
Page 117: Hard Disk Recording (Hd Recordcondition; Optional)
* Models with the /HD0 option are equipped with eSATA connectors. You need to purchase a hard disk that supports eSATA separately. For information about supported hard disks, contact your nearest YOKOGAWA dealer. A single DL850E/DL850EV cannot be equipped with both the /HD0 and /HD1 option.
Page 118: Time Base (Time Base)
5 Waveform Acquisition • Before you turn on the DL850E/DL850EV, connect the external hard disk to the DL850E/DL850EV, and turn on the external hard disk. If you connect a hard disk or turn it on after you turn on the DL850E/ DL850EV, the hard disk will not be detected.
Page 119 5 Waveform Acquisition Pulses per Rotation (Pulse/Rotate) When the time base is an external clock, you can specify how many pulses of the external clock signal (how many sampled data acquisitions) correspond to one mechanical rotation (or period). For example, if you set Pulse/Rotate to 100 pulses, when the record length is 1 kpoint, 10 rotations worth of sampled data will be acquired.
Page 120: Dual Capture (Dual Capture)
5 Waveform Acquisition Dual Capture (DUAL CAPTURE) You can use dual capturing to simultaneously acquire waveform data (main waveform) in low-speed roll mode and at a high sample rate (captured waveform).
