Page 6: Introduction
Photometer 7500 Bluetooth should always be used with genuine Palintest reagents for optimal performance. The fundamental operating technique applied to the Photometer 7500 Bluetooth is based on the principles of optical absorbance and scattering of visible light. Optical absorbance techniques are based on the use of Palintest (spectro)photometric reagents, creating visible colours with specific analytes upon reaction. - Page 7 The Photometer 7500 Bluetooth offers a choice of either mains power via the USB port or using three 1.5V ‘AA’ batteries (supplied). The Photometer 7500 Bluetooth is supported with a two year warranty and a full range of service, calibration and technical support. Support resources are available at www.palintest.com...

Page 19: Bluetooth Communication Off
Selecting this option transfers all or a selected group of results stored in the log to the paired mobile device. The Photometer 7500 Bluetooth will validate the paired connection and confirm readiness to transfer. Transferring selected data will require specification of the result log window e.g. -
Page 20: Bluetooth Device Id
Each data point is validated by the Aqua Pal app prior to upload of the next. If the connection is lost the Photometer 7500 Bluetooth will prompt for re-connection. If connection is not required or possible press Exit to disable Bluetooth and cancel the log transfer. -
Page 21: Hard Drive
5.5 USB Interface The waterproof USB interface provides both communication between the Photometer 7500 Bluetooth and a PC and an alternative mains power source via the adaptor. When connected the USB icon will appear, replacing the battery icon in the Info Panel, as power will be preferentially drawn from the external source. -
Page 22: Com Port
This allows backwards compatibility with software written for earlier models of Palintest instruments. In this mode, the PC requires installation of a USB virtual COM Port driver, available from www.palintest.com/know, and the availability of software operating as a virtual com port. -
Page 23: Test Selection Method
5.6 Test Selection Method The Photometer 7500 Bluetooth offers two distinct methods of selecting test parameters – Phot Number Entry Mode or Hotkey Entry Mode. Phot Number Entry Mode is active by default. Switching to Hotkey mode is carried out by enabling Hotkey Entry Mode in the Test Selection Method menu. -

Page 36: Calibration/Validation
7. Calibration/Validation Your Photometer 7500 Bluetooth is delivered with a calibration certificate validating the performance of the instrument as it leaves Palintest. We recommend annual service and calibration of all photometric instruments in normal use. The Photometer 7500 Bluetooth also includes an automatic routine to validate analytical performance using certified Palintest Check Standards. -
Page 37: Enter Check Standard Values
Press OK to return to the Check Standard Mode menu. Check Standard Measurement Follow the on-screen prompts to insert the Check Standards in the defined order. The Photometer 7500 Bluetooth will automatically measure the Transmittance at the required wavelength. Upon completion of the sequence the results are displayed on screen with pass or fail status. - Page 38 Know portal at www.palintest.com/know/ Palintest has focused on simplifying the test methods and equipment used for this technique but there are still a number of ways to ensure the results you generate are as accurate as possible: 1.
- Page 39 Good technique is to wipe the outside surface of the cuvette prior to inserting into the optical chamber to prevent contamination of the optical system. 7. Always use good quality, genuine Palintest cuvettes. Use the orientation mark to ensure repeatable positioning of the cuvette.
- Page 40 9. Always use the light cap provided to prevent ambient light affecting results. This is especially relevant when operating in strong sunlight or other light conditions. 10. Ensure your Photometer 7500 Bluetooth is operating effectively by using Palintest Check Standards and the Check Standard Mode (see Section 9 Calibration/Validation) and having the photometer serviced and calibrated at regular intervals.
- Page 41 Appendix 2 - Troubleshooting The Photometer 7500 Bluetooth features self-diagnostic software and hardware to optimise performance and battery life. The Info Panel indicates the status of the Photometer 7500 Bluetooth and any specific fault conditions are defined and displayed on screen.
- Page 42 Photometers may fail the Check Standard validation step due to the requirement for service/calibration. Contact your local Palintest partner for service and support. Ensure the Check Standards are inserted correctly, using the orientation mark to align and inserted fully. Use the light cap to prevent any ambient light interference.
- Page 43 Bluetooth Issues The Photometer 7500 Bluetooth features the latest Bluetooth SMART connectivity. I can’t connect the Photometer 7500 Bluetooth to my device Ensure your device is Bluetooth SMART ready.
