Inspect the RF connectors for any sign of wear or damage. Replace if
necessary.
•
Clean the connectors with alcohol or any acceptable dry cleaning fluid.
Long-term Storage
Do not store the instrument for long periods of time without recharging the
batteries. When the instrument is stored for long periods of time without use,
the batteries will loose their charge and also loose the ability to reach full
charge when put into service. To restore the battery charge, perform a full
charge for 16 hours. If the batteries are not fully charged after 16 hours, com-
pletely discharge the batteries then perform a full charge again. If necessary,
repeat this discharge and charge cycle up to three times. If the batteries do
not remain charged after three discharge-charge cycles, replace the batteries.
Calibration
The RF Power Analyst should be calibrated once each year or after any repair.
Required Equipment
Refer to Table 7 for test equipment needed to calibrate the RF Power Analyst.
