Self Test
The power meter has two self test modes:
– Power on self test - occurs automatically when you turn on the power meter.
– Troubleshooting mode - accessed via the front panel or remotely. The front
panel softkey menu allows you to run individual tests, whereas the remote
command runs a complete series of tests as listed in“Remote testing” on
page 264.

name of the test which is being performed. When each test is complete, the
message Testing... is replaced by either the message Passed or Failed. If a failure
occurs the message Power-up H/W Err appears. Any errors are also written to the
