Section 3 - Monitor Functions

The recorder clamping option, available when the +4 to +20 mA recorder output is
selected, allows the user to choose the recorder output level used to annunciate a
transducer not OK condition. With this option, the recorder output will clamp to 2
mA or +4 mA (user selectable) when a transducer is not OK.
SELF-TEST
- The monitor has three categories of self-test: Power-up, Cyclic, and User-
invoked.
Power-up self-test is performed automatically each time the monitor power is
turned on. A series of basic tests and transducer OK tests are performed.
Cyclic self-test is performed automatically during monitor operation. Errors
encountered during cyclic tests disable the monitor and flash the error code on the LCD
bargraph. If the error is intermittent, the monitor will resume operating, but the error
codes will be stored for retrieval during a User-invoked self test. Stored error codes are
indicated by the
OK
LEDs flashing at 5 Hz provided that the channel is OK.
User-invoked self-test performs the Power-up self test and lets you read and clear
error codes stored during cyclic tests. Stored errors are annunciated by flashing the
OK
LEDs at 5 Hz and displaying the error codes on the front panel LCD bargraph.
