TSI Instruments AIRFLOW Instruments ProHood PH721 User Manual

50 Electronic Balancing Tool EBT720/EBT721 and ProHood PH720/PH721
Error Code Possible Causes Corrective Action
43 Could not send RS232 data because the
receiving device was busy >10 seconds.
Make sure printer or computer is ready
to receive. Check RS232 interface
cable.
50 Pressure sensor zero voltage is too high. Return to factory if error re-occurs.
51 Pressure sensor gain out of range. Perform user calibration or return to
factory.
52 Lithium battery voltage is too low. Replace lithium battery or return to
factory.
53 AD7708 A to D converter calibration
factor out of range.
Return to factory.
54 AD7718 A to D converter calibration
factor out of range.
Return to factory.
55 User entered flow temperature out of
range.
The micromanometer has reset the
temperature to 70.0°F (21.1°C) to
correct it.
56 Barometric pressure zero factor out of
range.
Return to factory.
57 Barometric pressure span factor out of
range.
Return to factory.
58 Offset factor for user temperature sensor
calibration out of range.
Re-do user calibration, set temperature
sensor calibration to FACT, or return to
factory.
59 Slope factor for user temperature sensor
calibration out of range.
Re-do user calibration, set temperature
sensor calibration to FACT, or return to
factory.
60 Humidity sensor voltage at 20% RH out of
range.
Perform user calibration or return to
factory.
61 Humidity sensor voltage at 80% RH out of
range.
Perform user calibration or return to
factory.
62 Pressure sensor gain factor A out of range. Perform user calibration or return to
factory.
63 Pressure sensor gain factor B out of range. Perform user calibration or return to
factory.
64 Pressure sensor gain factor C out of range. Perform user calibration or return to
factory.
68 Pressure sensor divider calibration out of
range.
Return to factory.
69 A to D reference voltage out of range. Return to factory.
70 5V reference voltage out of range. Return to factory.
71, 72 An invalid K-Factor was corrected. The micromanometer has set the K-
factor to 1.0 to correct it.
74 Pressure voltage for user pressure
calibration out of range.
Re-do user calibration.
