3.4 Self-Test Diagnostics
The PM295 periodically performs self-test diagnostics. If the instrument fails the
self-test diagnostics, it discards the last measurement results, and an error code is
displayed for one second on all LEDs. Error codes are listed in Table 3.1. Frequent
failures may be result of excessive electrical noise in the region of the instrument. If
the instrument resets itself continuously, contact your local distributor.
