3.0 SET-UP This section provides the necessary information to set the OM-550 up for proper operation. 3.1 POWER CONNECTION As previously discussed there are several options to supply power to the OM-550 and the following sections explain how to use them. 3.1.1 BATTERY INSTALLATION Slide the battery cover open and insert the batteries as shown below. -
Page 24: Connecting The Ac Power Adapter
3.1.2 CONNECTING THE AC POWER ADAPTER Plug the AC Power Adapter into an appropriate 120V AC (in North America) power outlet. Insert the adapter's connector into the receptacle on the left side of the unit. The OM-550 is now ready to operate on external power. The OM-550 will operate without batteries but data may be lost if the power fails or the AC Power Adapter is accidentally removed. -
Page 25: Paper Installation
3.2 PAPER INSTALLATION 1. Unwind several inches of paper from the paper roll. 2. Fold the end of the thermal paper over creating a straight flat edge as shown in Figure 3-2. This creates a strong edge and allows the paper properly center in the printer when inserting it into the rear paper slot. -
Page 26: Data Port Connection
3.3 DATA PORT CONNECTION Prior to transferring data, the OM-550 must be connected to a PC with the RS-232 cable assembly supplied with the kit. The cable assembly includes a telephone-style cable and two adapters. The OM-550 for Windows software supplied with the kit is used to transfer data through the OM-550 RS-232 Port to a PC for analysis and storage. -
Page 27: Programming
4.0 PROGRAMMING When prior to operating the OM-550 it must first be programmed. This section covers all of the programming options available. All programmed settings but the time & date are stored in EEPROM and retained even if the batteries are removed. Programming outline: 1. -
Page 28: Programming Keys
4.1 PROGRAMMING KEYS Pressing the PROG key activates the Program mode. The unit immediately prints the current programming information and prompts the user to select a channel to reprogram: CURRENT TIME AND DATE DATA CACHE INFORMATION THE PROGRAM COMMAND Channels may be defined as Voltage, Temperature (T/C) or Skipped. To save paper and speed programming, the definitions for Skipped channels are not printed in the above listing. -
Page 29: Print Formatting
4.2 PRINT FORMATTING When a Voltage channel (or the Math) channel is programmed, the OM-550 prompts the user for a decimal point position (or decimal point fix). This number between 0 and 5 is the location of the decimal point in the print field. POSITION Any five-digit data value between "±.00000"... -
Page 30: Temperature Channels
4.3 TEMPERATURE CHANNELS Any of the five channels can be programmed as Temperature channels. The user may select one of the four standard thermocouple types: J, K, T, or E and three optional types: B, S, or R. The Thermocouple types can be mixed. For example, channel #1 with a Type E thermocouple and channel #2 with a Type J thermocouple may be used. -
Page 31: Math Pseudo-Channel
4.5 MATH PSEUDO-CHANNEL The OM-550 has five physical channels and a sixth "channel" that can display the result of a math operation involving any two of the other channels (or a single channel, twice). The channels chosen as a basis for the Math channel are its "constituents". The Math channel can be activated or "skipped"... -
Page 32: Log Interval
4.6 LOG INTERVAL The each active channel is scanned once during each log interval. The Log Interval is the time between readings, expressed in HH:MM:SS (hours:minutes:seconds). It can be programmed from one second to one day (00:00:01 to 23:59:59). The Keypad has no colon key, so enter the log interval as six numbers and the colons will automatically be inserted. -
Page 33: Operation At Full Cache (Recording Time)
4.7 OPERATION AT FULL CACHE (RECORDING TIME) The OM-550 includes a battery-backed, 28-Kb data cache. The cache is erased when the RUN or PROG keys are pressed and new data is stored during logging. The OM- 550 can be programmed to stop when the data cache is full or to log continuously and overwrite the oldest data when the cache fills. -
Page 34: Date
4.8 DATE The current date is entered during programming and is kept in a real-time clock that is backed by the AA batteries. The clock will then be accurate unless the batteries are removed or a Manual Reset is executed. The Keypad has no colon key, so enter the date as six numbers and the colons will automatically be inserted as necessary. -
Page 35: Calibration Mode
4.12 CALIBRATION MODE The OM-550 includes a Cold-Junction Compensation network server that is automatically disabled during temperature calibration. Calibration mode temperature measurements performed in the usual manner will appear abnormal with the OM-550 in the CAL mode. When the OM-550 is in the CAL mode, the time and date are printed with additional characters: UNUSUAL FORMAT DENOTES CAL MODE To return to Normal mode:... -
Page 36: Tadjust
4.13 TADJUST Tadjust is a cumulative value set during programming and summed with each Temperature channel's data during logging. It is cleared to a value of +00.0 at Manual Reset and on entry to the CAL mode. Use Tadjust to correct temperature readings for batch variances in thermocouple wire or to align the readings with another measurement device. -
Page 37: Voltage Input Scaling
4.14 VOLTAGE INPUT SCALING Any of the input channels (1 through 5) may be programmed as Voltage channels. Each Voltage channel includes unique m and b constants for "scaling" data to your application. These constants default to +1.00000 and 000000, respectively, when the channel is first programmed as a Voltage channel but the user may reprogram them as necessary. -
Page 38: Matching A Current Transducer
4.14.3 MATCHING A CURRENT TRANSDUCER Use one resistor to develop the necessary voltage at the input: TRANSDUCER OUTPUT The 4-20 mA Current Probe uses this technique (with R1=100 current to a 0.4-2.0 VDC signal. OM-550 Figure 4-9 = OM-550 maximum input voltage = 2.0000 VDC = R1 * I = 1/2 transducer's maximum output current... -
Page 39: Data Scaling (Mx + B Calculation)
4.14.4 DATA SCALING (mX + b calculation) The output voltage of a properly matched transducer can be read the but the data will be in "volts" and the user might prefer data in units that reflect the application. Programming the OM-550 to produce data in terms of the actual parameter being measured is called Scaling. -
Page 40: Matching And Scaling A Voltage Transducer
4.14.5 MATCHING AND SCALING A VOLTAGE TRANSDUCER EXAMPLE: Given a 20 - 90 % RH (Relative Humidity) transducer with a 0 - 10 VDC output at a maximum current of 3 mA. Program the OM-550 to indicate 20.00 %RH to 90.00 %RH (that is, to indicate %RH with 0.01% resolution). - Page 41 3. Next, find m & b: = 0 VDC 0 A/D counts = 2.0000 VDC 20000 A/D counts = 20.00 %RH 2000 display counts = 90.00 %RH 9000 display counts = (Y1 - Y2) / (X1 - X2) (2000 - 9000) / (0 - 20,000) 0.35000 Y2 - (m * X2) 9000 - (0.350 * 20,000)
