Replacing And Recalibrating The Moisture Probes - GE PM880 User Manual

Remove the probe cable by pulling back the spring-loaded
N o t e :
sleeve and pulling the cable out of the connector.
For maximum accuracy you should send moisture probes back to
the factory for recalibration every six months to one year,
depending on the application. Under severe conditions you
should send the probes back for recalibration more frequently; in
milder applications you do not need to recalibrate probes as often.
Contact a GE Infrastructure Sensing applications engineer for the
recommended calibration frequency for your application.
You can program the PM880 to remind you when it is time
N o t e :
to send the probes back for recalibration. Refer to Setting
a Probe Calibration Reminder page 4-6
When you receive new or recalibrated probes, be sure to follow
the instructions in Chapter 1, Getting Started, to install, connect
and enter calibration data for the probe(s). Note that each probe
has its own Calibration Data Sheet with the corresponding probe
serial number printed on it.
You do not have to enter calibration data for the Moisture Image
Series (MIS) Probe if you returned both the sensor and the
electronics module to the factory for recalibration. However, you
should verify that the calibration data entered at the factory is
correct (see Entering Setup Data on page 1-7). If you only sent
the sensor part of the MIS Probe to the factory without the
module, you must enter the calibration data manually.
