What does Error Code 58 mean on a TSI Instruments Power Tool?
If your TSI Instruments Power Tool displays Error Code 58, it means the offset factor for user temperature sensor calibration is out of range. You can try re-doing the user calibration or setting the temperature sensor calibration to FACT.
What does Error Code 33 mean on my TSI Instruments Power Tool?
If your TSI Instruments Power Tool shows Error Code 33, it means that while performing user calibration of the hood temperature sensor or accessory temperature sensor, the accessory temperature/humidity probe was found instead. Plug in the selected probe.
How to fix a TSI Instruments Power Tool with no display?
If the TSI Instruments Power Tool's display is not showing anything, there could be several reasons: * The unit might not be turned on. Try pressing the I/O key. * The batteries could be low or dead. Replace them with fresh ones. * The battery contacts might be dirty. Clean them carefully. * The AC adapter might not be connected. Ensure it is properly plugged in.
What does Error Code 31 mean on a TSI Instruments Power Tool device?
If your TSI Instruments Power Tool displays Error Code 31, it means the pressure calibration voltage at 5 in. H2O must be less than the pressure calibration voltage at 15 in. H2O. Make sure calibration pressures are correct.
What does Error Code 30 mean on my TSI Instruments Power Tool?
If your TSI Instruments Power Tool displays Error Code 30, it indicates that the pressure calibration voltage at 1 in. H2O must be less than the pressure calibration voltage at 5 in. H2O. Ensure that the calibration pressures are correct.
What does Error Code 36 indicate on a TSI Instruments Power Tool?
If your TSI Instruments Power Tool displays Error Code 36, it means the flap closed pressure was less than the flap open pressure, or the flap open versus flap closed pressure ratio exceeds allowed limits. Try taking the data again.
What does Error Code 35 mean on a TSI Instruments Power Tool?
If your TSI Instruments Power Tool shows Error Code 35, it indicates that the barometric pressure measured was greater than 40.00 in. Hg. This means the barometric pressure is too high to take a reading.
What does Error Code 34 signify on a TSI Instruments Power Tool?
If your TSI Instruments Power Tool displays Error Code 34, it means the barometric pressure measured was less than 15.00 in. Hg. The barometric pressure is too low to take a reading.
What does it mean when my TSI Instruments Power Tool shows '8888' flashing?
If the display on your TSI Instruments Power Tool is flashing “8888”, it means the temperature is too high to measure. Check the specifications page for the maximum temperature.
What does error code 11 mean on my TSI Instruments Power Tool?
If your TSI Instruments Power Tool shows Error Code 11, it indicates that the AC adapter voltage is too high. Ensure you are using the correct AC adapter.
