Safety Summary
Safety Considerations
The following general safety precautions must be observed during
all phases of operation, service, and repair of this instrument.
Failure to comply with these precautions or with specific warnings
elsewhere in this manual violates safety standards of design,
manufacture, and intended use of the instrument. Hewlett-Packard
Company assumes no liability for the customer's failure to comply
with these requirements.
General This is a Safety Class 1 instrument (provided with
terminal for protective earthing) and has been manufactured and
tested according to international safety standards.
Before operation, you should 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 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.
To avoid hazardous electrical shock, do not perform electrical tests
when there are signs of shipping damage to any portion of the outer
enclosure (covers, panels, and so on).
Line Power Requirements
The HP 8163A Lightwave Multimeter can operate from the single-
phase AC power source that supplies between 100 V and 240 V at a
frequency in the range 50 to 60 Hz. The maximum power
consumption is 120 VA with all options installed.
