Why does the measurement value freeze and not change on my Thermo Scientific Orion Star A214?
- K
  Kenneth MerrittAug 12, 2025
  If the measurement value freezes on your Thermo Scientific Measuring Instruments and doesn't change, it might be because the read type is set to Auto-Read mode (indicated by the AR icon on the display). To resolve this, press the measure (esc) key to initiate a new measurement. Alternatively, you can navigate to the setup menu and change the read type to continuous.

What to do if the Thermo Scientific Measuring Instruments meter keypad is unresponsive when using the Star Com computer software?
- S
  Steven SingletonAug 16, 2025
  If your Thermo Scientific Measuring Instruments meter keypad is unresponsive when using the Star Com computer software, it's likely because the keypad lock option is enabled within the Star Com program. To disable it, open the Star Com program, click the Settings icon, uncheck the box next to Keypad Lock, and then click the Save icon.

Why doesn't my Thermo Scientific Orion Star A214 meter automatically recognize the pH buffer during calibration?
- C
  coreyandersonAug 19, 2025
  If your Thermo Scientific Measuring Instruments meter does not automatically recognize the pH buffer during calibration, it could be due to the electrode aging or becoming dirty, which causes its mV readings to drift. To fix this, first verify that you've selected the correct buffer set in the setup menu. Then, check the buffers and clean the electrode according to the instructions in the electrode manual, as the meter relies on raw mV readings to recognize the buffer.

What to do if the Thermo Scientific Measuring Instruments meter display goes blank, shows random lines or intermittently freezes?
- J
  Justin GreenAug 23, 2025
  If your Thermo Scientific Measuring Instruments meter display goes blank, shows random lines, or intermittently freezes, ensure you are using the correct power supply specifically designed for the Star A series meter. Note that this power supply differs from the one provided with Thermo Scientific Orion Versa Star meters. It's also recommended to use a surge protector or uninterruptible power supply (UPS). Additionally, try performing a factory reset on the meter.

What to do if the Thermo Scientific Orion Star A214 meter locks up while connected to a computer via the USB cable?
- J
  Joshua WilsonAug 27, 2025
  If your Thermo Scientific Measuring Instruments meter is locking up while connected to a computer via the USB cable, try disconnecting 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 doesn't the Thermo Scientific Orion Star A214 meter recognize the conductivity standard during calibration?
- C
  Caroline CuevasAug 30, 2025
  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 sensor you are calibrating. Also, make sure that the conductivity standard is one that the meter can automatically recognize. Try recalibrating the conductivity sensor using a fresh conductivity standard.

How to fix a Thermo Scientific Orion Star A214 that is flashing 9999 and displaying Over Range or Under Range?
- S
  Scott SimmonsSep 4, 2025
  If the measurement value on your Thermo Scientific Measuring Instruments is flashing 9999 and displaying Over Range or Under Range, verify that the correct channel is selected on the meter display. Also, ensure that the electrode or sensor is securely and fully connected to the meter.

What to do if the Thermo Scientific Measuring Instruments meter does not recognize an RDO optical or polarographic dissolved oxygen sensor?
- J
  Jamie GutierrezSep 7, 2025
  If your Thermo Scientific Measuring Instruments meter does not recognize an RDO optical or polarographic dissolved oxygen sensor, ensure that the dissolved oxygen sensor is fully connected to the meter and confirm that the correct channel is displayed on the meter. After connecting the dissolved oxygen sensor, wait approximately 15 seconds for the meter to recognize the DO sensor type. Press the measure (esc) key to initiate a new measurement and update the meter display.
