The value displayed on the RX3 meter must match the reference value that appears in the
inspection report and on the label of the calibrated jumper.
If these values do not match, ensure that the FC/APC connector is properly connected to the
meter, and clean all the connectors. If the values still do not match to within ±0.3 dB, adjust the
backreflection calibration:
1. Press the MENU key to access Menu mode.
2. Press the soft key labeled MORE MENUS.
3. Press and hold the unlabeled (fourth) soft key until the calibration menu is displayed.
4. Press the soft key labeled CALIBRATE BR. The menu selections CAL and CLR are
displayed.
5. To enter a new calibration setting, select CAL. To restore the original factory settings, select
CLR. To exit the calibration menu without modifying any settings, press the MENU key.
If CAL is selected, the meter displays a series of prompts for each step remaining in the
calibration procedure:
1. Press the
or key to adjust the values displayed on the meter until these match the value
marked on the calibrated jumper.
2. Press the soft key labeled DONE.
3. Connect each of the outputs to the external detector in sequence, and press the soft key
labeled DONE after each output is connected. For the first channel only, connect the jumper
between the output and the detector.
Each time the meter makes a measurement, the top soft key is labeled MEAS. To make the
measurement again (and ensure that the value has not changed), clean and reconnect the last
connection made, and press the MEAS key. If the values differ significantly, repeat this
procedure until the values match.
1. Disconnect the calibrated jumper from the detector, and clean the connector end.
Any residue on the connector end can affects its reflection in air. Clean the connector end
thoroughly with a lint-free tissue and alcohol, and rub the connector end against a clean lint-free
tissue laid on a flat surface. The measurement must be repeated using the MEAS function to
ensure its accuracy and stability. See the
Cleaning Connectors section.
Power Calibration Adjustment
To perform a power calibration adjustment:
1. Press the POWER key to set the meter to Absolute Power mode, which is indicated on the
screen as ABS.
