Why does Thermo Scientific Measuring Instruments show Over Range or Under Range?
This occurs when the measurement is outside the allowable measurement range. Ensure the electrode or probe is fully connected with the measurement module, and verify the correct channel is shown on the meter display.
What to do if Thermo Scientific Measuring Instruments freezes and won't change?
If the measurement value on your Thermo Scientific Measuring Instruments freezes, it might be because the read type is set to Auto-Read mode (AR icon shown on the display). To resolve this, press the measure (esc) key to take a new measurement. Alternatively, you can change the read type to continuous in the setup menu.
What to do if Thermo Scientific Measuring Instruments meter locks up while connected to a computer via the USB cable?
If your Thermo Scientific Measuring Instruments meter locks up while connected to a computer via the USB cable, disconnect the USB cable from both the meter and the computer. Then, disconnect and reconnect the power adapter from the meter. Finally, reestablish the USB connection between the meter and the computer.
Why does Thermo Scientific Orion Versa Star Pro Measuring Instruments meter not automatically recognize the pH buffer during calibration?
The meter may fail to automatically recognize the pH buffer during calibration if the electrode is aging or dirty, causing its mV readings to drift. To fix this, verify that the correct buffer set was selected in the setup menu, as the meter uses raw mV readings to recognize the buffer. Also, check the buffers and clean the electrode.
Why does Thermo Scientific Orion Versa Star Pro Measuring Instruments meter display go blank?
If the display on your Thermo Scientific Measuring Instruments goes blank, shows random lines, or intermittently freezes, ensure that you are using the correct power supply specifically designed for the Versa Star Pro meter, as it differs from power supplies used with other Thermo Scientific Orion meters. It is also recommended to use a surge protector or an uninterrupted power supply (UPS).
How to fix Thermo Scientific Orion Versa Star Pro Measuring Instruments meter not recognizing RDO optical or polarographic DO probe?
If your Thermo Scientific Measuring Instruments meter does not recognize an RDO optical or polarographic DO probe, ensure that the DO probe is fully connected with the measurement module and verify the correct channel is shown on the meter display. After connecting the DO probe, wait about 15 seconds for the meter to recognize the DO probe type. Then, press the measure (esc) key to initiate a new measurement and update the meter display.
What to do if Thermo Scientific Measuring Instruments channel ID icon does not show that a measurement module is connected?
If the channel ID icon on your Thermo Scientific Measuring Instruments does not indicate that a measurement module is connected, first, check that the module is properly connected to an open channel on the meter. Try removing the module and reinserting it into a different channel.
Why does Thermo Scientific Orion Versa Star Pro Measuring Instruments meter not recognize the conductivity standard during calibration?
If your Thermo Scientific Measuring Instruments meter does not recognize the conductivity standard during calibration, verify that the correct nominal cell constant is entered in the setup menu for the conductivity probe being calibrated. Also, ensure that the conductivity standard is one that can be automatically recognized by the meter. Try recalibrating the conductivity probe using a new conductivity standard.
What to do if Thermo Scientific Orion Versa Star Pro shows 'Module not detected'?
To resolve the 'Module not detected' message on your Thermo Scientific Measuring Instruments, insert at least one module into an open channel on the meter. Once the module is detected, the meter will display the main measurement screen for that measurement module.
