Michael SparksJul 27, 2025
If your Thermo Scientific Measuring Instruments display the message 'Module not detected … Plug in module to start Measurement' upon power up, it means that the module is not properly connected or not inserted. To resolve this:
* Insert a module into the meter so that the main measurement screen for that parameter will be displayed.
* Check that the module is fully connected to the meter.

What to do if Thermo Scientific Control Unit measurement is flashing 9999?

Heather AguilarAug 2, 2025
If the Thermo Scientific Control Unit's measurement flashes 9999, indicating an over-range or under-range condition, the measurement is outside the allowable range. First, check the electrode connection and settings in the setup menu. Then, clean the electrode according to the electrode user guide and recalibrate it using new buffers or standards. If the error persists, run the meter self-test, which can be found in the diagnostics menu.

Brandon PrinceAug 8, 2025
To resolve an out-of-range measurement on your Thermo Scientific Control Unit when it should be in range, ensure the conductivity probe is fully immersed in the solution. Also, review the settings in the setup menu, paying close attention to the cell constant and temperature-related settings.

Why does the measurement freeze on my Thermo Scientific Control Unit?
D
Dr. Lydia Neal MDAug 15, 2025
If the measurement on your Thermo Scientific Control Unit freezes and doesn't change, it's likely because the meter is in AutoRead mode. To take a new reading, press the measure (esc)/1 key. Alternatively, you can change the read type in the setup menu.

How to calibrate Thermo Scientific Control Unit if it does not recognize the conductivity standard?

Deanna MartinAug 21, 2025
If the Thermo Scientific Control Unit doesn't recognize the conductivity standard during calibration, verify that the default cell constant was entered correctly in the setup menu. The cell constant is usually printed on the conductivity probe cable. Check that the constant is one of the standard values auto-recognized by the meter. Then, recalibrate using a fresh standard.
