Appendix A. Installation and Maintenance
Safety Considerations
A.1 Safety Considerations
The HP 8163A Lightwave Multimeter and the HP 8164A
Lightwave Measurement System are Safety Class 1 instruments
(that is, instruments with a metal chassis directly connected to earth
via the power supply cable). The shown symbol is used to show a
protective earth terminal in the instrument.
Before operation, review the instrument and manual for safety
markings and instructions. You must follow these to ensure safe
operation and to maintain the instrument in safe condition.
Some HP 8164A Lightwave Measurement System circuits are
powered whenever the instrument is connected to the AC power
source. To disconnect from the line power, disconnect the power
cord either at the rear power inlet, or at the AC line power source
(receptacle). One of these must always be accessible. If the
instrument is in a cabinet, it must be disconnected from the line
power by the system’s line power switch.
A.2 Initial Inspection
Inspect the shipping container for damage. If there is damage to the
container or cushioning, keep them until you have checked the
contents of the shipment for completeness and verified the
instrument both mechanically and electrically.
The Function Tests give a procedure for checking the operation of
the instrument. If the contents are incomplete, mechanical damage
or defect is apparent, or if an instrument does not pass the
operator’s checks, notify the nearest Hewlett-Packard Sales/Service
Office.
