When Err is displayed on a temperature sensor with a probe, this may be the result of inserting a new probe or reinserting a probe into the sensor jack and not resetting its Lo/Hi collection period.
-
For 1 second, press and hold the sensor Silence button
(bell icon). A single beep is emitted when the reset is complete.
This will clear the Err state and resets the Lo/Hi Collection Period.
From the LCD screen verify the readings are displaying (Lo, Hi, and Cur).
-
If this is a new probe, press and quickly release the sensor Check-In button
(up arrow). This will send the new probe serial number update to OneVue.
Verify the probe serial number update: From OneVue go to Monitoring > Monitored Assets > select the Name of asset the sensor is monitoring > from the Sensor Type section, select the Temperature link. From the sensor profile's Probe Life section, verify the Probe Serial Number is the same as the number printed on the tag attached to the probe.
