User's Manual

3.2 Moisture Probe Error Conditions

IMPORTANT:

All moisture probes require periodic recalibration and cleaning to maintain optimum accuracy. Consult

the Panametrics service center for the recommended probe -cleaning interval for your application.

If there is a problem with the moisture probe during operation, the HygroPro

is programmed to indicate the error

condition via its 4 – 20 mA analog output signal.

Note:

The NAMUR error handling scheme described below is followed only if the analog output is set to NAMUR as

shown in Section 2.2.4 of Chapter 2.

•

≥

22 mA to indicate an Over Range error, i.e., a short circuit in the AlOx sensor on the probe

•



3.5 mA to indicate an Under Range error, i.e., an open circuit in the AlOx sensor on the probe

After completing the above step, respond to the

“Are you sure?” question. Be sure to respond Yes, if

you wish to save the new information.

Please note your input has not been accepted until

the display echoes the choice selected by

indicating briefly on the display, “Save Successful”.

Please refer to Section 2.3.5 in the end of Chapter 2

to understand how to display the firmware,

calibration, and hardware information about the
HygroPro

display and /or HygroRTE probe.

The firmware of the display and/or the probe can be

updated in the field via the RS-485 port. Please see
Appendix B HygroPro

Field Service Update of this

user manual for detailed instructions.

Run-time errors can also be displayed on the HygroPro

LCD (in a

specific pre-assigned spot) as well as by HART.

The figures on the left show the location of both the Calibration

Reminder !CR error as well as the other Error codes.
Table 7 below lists all error codes displayed HygroPro

screen.
