129 Appendix C Maintenance
General
The Model 8718B requires very little maintenance. No operator
adjustments are required. The electronic circuitry is contained
in a very rugged aluminum housing. However, this housing is
not watertight and should not be immersed in water. The LCD
display and the case may be cleaned using a damp cloth. Do
not use any type of detergent or solvent.
Calibration
The Model 8718B is calibrated before it is shipped. Narda
recommends that the Model 8718B be calibrated every two
years. Narda will perform this calibration for a nominal charge.
The meter is completely tested using Automated Test Equipment
(ATE) as part of the calibration service.
Replacement Parts
None of the parts within the meter are considered user
serviceable. The table below contains the model numbers and
part numbers of the accessories supplied with the 8718B and
available as optional accessories.
