Check sensor location for external interference. Perform zero calibra-
tion. If problem persists after zero calibration and no interference exists,
replace sensor.

W007
Calibration
Required
All Non-latching 2 seconds
Number of days
remaining until
calibration ex-
pires, negative
= number of
days expired
Time since the last span calibration has exceeded a dened limit. Per
-
forming a successful span calibration will clear the condition. The limit is
the user-dened calibration interval. W007 can be disabled by setting the
calibration interval to 0.
