10.6 RH/TEMPERATURE PROBE
The RH/Temperature probe should be calibrated on a regular basis. A good calibration schedule is annually,
however your calibration practices may be different. The probe can only be calibrated by ECD and can be eas-
ily removed and returned. Because the calibration information is kept internal to the probe, a replacement
probe can be purchased and “swapped” when it comes time to calibrate.
To remove and or swap the RH/Temperature probe, please follow these steps:
1) ALWAYS disconnect the cabinet from the power cord from the power supply before replacing the
probe.
2) Remove the control chassis top cover screws located on the cover’s back.
3) Slide the cover back about 20mm (1”) and lift off the top. Be careful to prevent the cover from falling
inside the control chassis.
4) Find the probe in the back left corner of the control chassis. Using two hands, press the plug release
lock and carefully disconnect the probe cable.
5) Loosen the probe locking collar by turning it counter clockwise and lift out the probe.
6) Lower the replacement probe into the locking collar and secure by turning the collar clockwise. Finger
tight is all that is needed.
7) Reconnect the cable making sure the orientation is correct and the release lock latches into place.
8) Replace the top cover and the fastening hardware BEFORE connecting the power cord to the power
supply.
9) Return the Probe for calibration by obtaining an RMA number on the ECD website or calling ECD Ser-
vice at 1-800-323-4548. Refer to section 11.0 Service and Troubleshooting for additional information.
