Why does my Ogden Computer Hardware display blink and change values by itself?
- M
  marvinharrisAug 20, 2025
  If your Ogden Computer Hardware display blinks or entered values change on their own, it could be due to electromagnetic interference (EMI) or radio frequency interference (RFI). Try suppressing arcing contacts in the system to eliminate high voltage spike sources, and separate sensor and controller wiring from 'dirty' power lines, ground heaters. Alternatively, the EEPROM might be defective, requiring replacement.

  Rebecca ReevesAug 22, 2025
  If your Ogden Computer Hardware shows no heat or output, first check the output wiring and output device to ensure they are correctly connected and functioning. Also, verify that the correct output device is being used. If the output device is defective, it should be replaced. Finally, inspect the output fuse outside of the instrument and replace it if it's open.

Why is the display unstable on my Ogden Computer Hardware?
- D
  dukedavidAug 25, 2025
  If your Ogden Computer Hardware display is unstable, it could be due to a defective analog portion or A-D converter, in which case you should replace the related components or board. Another possibility is a defective thermocouple, RTD, or sensor; check these components. Also, check the sensor wiring connections for any intermittent issues.

Why does the display go in reverse direction on my Ogden ETR-9090?
- M
  Mrs. Beth MossAug 31, 2025
  If your Ogden Computer Hardware display goes in the reverse direction (counts down as the process warms), it's likely due to reversed input wiring of the sensor. Check the wiring and correct it.

Why are some segments of the display or LED lamps not lit on my Ogden Computer Hardware?
- P
  Patricia GrantSep 6, 2025
  If some segments of the display or LED lamps on your Ogden Computer Hardware are not lit or lit erroneously, it could be due to a defective LED display or LED lamp, which would need to be replaced. Alternatively, the related LED driver might be defective, in which case you should replace the related transistor or IC chip.
