Note: Zeroing the sensor takes 60 seconds. The bar graph will display
calibration progress.
Note: When complete, “PASS” should be displayed.
3. Press Enter to return to normal operation when zeroing is complete.
Note: If “FAIL” is displayed, make sure no RF power is applied to the
sensor and perform the procedure again.
TPS-EF
The Bird TPS-EF uses frequency correction factors to allow more accurate mea-
surements. Look at the label on the side of the sensor and find the correction
factor for the frequency being measured. Add the correction factor to the other
attenuation or coupling factors and enter this as an offset.
Wideband Power Sensor (WPS)
A status LED on the front lights when the WPS is powered, and blinks when the
WPS is connected to the DPM.
Zeroing Sensor
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.
Make sure the sensor has reached a stable operating temperature.
2. Make sure no RF power is applied to the sensor.
3. Press and hold “0” for two seconds to begin zero calibration.
Note: “Zero/Cal” will be displayed and calibration will begin.
Note: Zeroing the sensor takes 60 seconds. The bar graph will display
calibration progress.
Note: When complete, “PASS” should be displayed.
4. Press Enter to return to normal operation when zeroing is complete.
Note: c.If “FAIL” is displayed, make sure no RF power is applied to
the sensor and perform the procedure again.
WARNING
Do not interrupt the calibration.
