Chapter 3 Operation
Zeroing Sensor
5000-EX
Over time, the sensor’s “zero value” (reading with no applied RF power) can
drift due to environmental factors (temperature, humidity, etc.) This can make
the readings performed by this sensor less accurate by the drift value. If the drift
would be a significant error, re zero the sensor.
1. Ensure the sensor has reached a stable operating temperature.
2. Ensure no RF power is applied to the sensor.
3. Press “Zero” to begin Calibration.
Note: Calibration will take about 40 seconds. Do not interrupt the
calibration! A bar on the screen will display calibration progress.
4. Do one of the following:
If the calibration is successful, “Cal Pass” or “Calibration
Complete” will be displayed.
a. Press any key to return to normal operation.
If calibration fails, “Cal Fail” will be displayed.
a. Press a key to return to normal operation,
b. Ensure that the WPS is properly connected, and the RF is off.
c. Rezero. Go back to Step 3.
