What does error code 14 mean on my TSI Instruments Power Tool?
If your TSI Instruments Power Tool shows Error Code 14, this indicates an accessory temperature/humidity probe checksum error for humidity. You can try to perform user calibration.
What to do if the TSI Instruments Power Tool has a flashing symbol on the display?
If you see a flashing symbol on the display of your TSI Instruments Power Tool, it typically indicates: * Low battery charge. You should replace or recharge the batteries. * Dirty battery contacts. Cleaning the battery contacts might resolve the issue.
What does Error Code 43 mean on a TSI Instruments Power Tool?
If your TSI Instruments Power Tool shows Error Code 43, it means the device couldn't send RS232 data because the receiving device was busy for more than 10 seconds. To resolve this: * Ensure that the printer or computer is ready to receive data. * Check the RS232 interface cable for any issues.
Why is '888888' flashing on the display of my TSI Instruments Power Tool?
If your TSI Instruments Power Tool displays “888888” flashing, it indicates that the pressure is too high to measure, or if measuring velocity or flow, the pressure at that velocity is too high. Refer to the specifications page to check the maximum pressure.
What does Error Code 10 mean on a TSI Instruments Power Tool?
If your TSI Instruments Power Tool is showing Error Code 10, it means that the AC adapter voltage is too low. You should use the correct AC adapter.
What does Error Code 63 mean on a TSI Instruments Power Tool?
If your TSI Instruments Power Tool displays Error Code 63, it indicates that the pressure sensor gain factor B is out of range. Try performing user calibration.
What does Error Code 61 mean on a TSI Instruments Power Tool?
If your TSI Instruments Power Tool displays Error Code 61, it means the humidity sensor voltage at 80% RH is out of range. You can try performing user calibration.
What does Error Code 62 mean on a TSI Instruments Power Tool?
If your TSI Instruments Power Tool displays Error Code 62, it indicates that the pressure sensor gain factor A is out of range. Try performing user calibration.
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 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.
