Safety Considerations
Before operation, review the instrument and manual, including the red safety
page, for safety markings and instructions
.You must follow these to ensure safe
operation and to maintain the instrument in safe condition.
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 veried the instrument both mechanically and electrically.
The Performance Tests give procedures 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 oce.
Warning
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, etc.).
Line Power Requirements
The HP 81554SM operates when installed into the HP 8153A Lightwave
Multimeter mainframe
Operating Environment
The HP 8153A safety information summarizes the HP 81554SM operating
environment ranges. In order for the HP 81554SM to meet specications, the
operating environment must be within the limits specied for the HP 8153A.
Storage and Shipment
The module can be stored or shipped at temperatures between 0 40

C and
+70

C. Protect the module from temperature extremes that may cause
condensation within it.
