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 81551MM operates when installed into the HP 8153A Lightwave

Multimeter mainframe

Operating Environment

The HP 8153A safety information summarizes the HP 81551MM operating

environment ranges. In order for the HP 81551MM 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 between040

C and

+70C. Protect the module from temperature extremes that may cause

condensation within it.
