CQM (Contact Quality Monitor) Test
The CQM test measures the resistance needed by the ESU device to activate
the CQM alarm. For this test the 454A requires an auxiliary module, either
the REM/ARM module or the combined REM/ARM and Return Fault
module (RARF).
Press
F5 READY
to start the test. Connect the ESU analyzer and the ESU
device for a CQM (REM/ARM) test. On the 454A and 402, adjust the
resistance on the module until the ESU alarm is activated. On the RF303
RS
, a
CQM test uses the analyzer’s main test load and defaults to 100 ohms. You
can adjust this level when it is displayed on the RF303
RS
during a CQM test
by pressing the INCREASE/DECREASE TEST LOAD keys on the
RF303
RS
front panel until the desired resistance value is displayed. Press
F5
READ
to read the resistance on the medTester. You can accept this reading
and store PASS or FAIL by pressing
F4 PASS
or
F5 FAIL
respectively. FAIL
stores a "#" with the test record. You can press
F3 REPEAT
to go back to the
measurement screen.
Return Fault Test (for Model 454A only)
This test checks the return fault monitor on an ESU. For this test the 454A
requires the EM/ARM and Return Fault module (RARF). The setup screen
prompts the user to set up the ESU for power setting and to select either the
cut or coag side of the ESU device.
Press
F5 READY
to start. Connect the ESU to the ESU analyzer for a return
fault monitor test. First, the ESU analyzer sets up the No Fault condition.
The ESU should not alarm. Press
F4 PASS
or
F5 FAIL
to store the test results.
As before, FAIL stores a "#" along with it. Second, the ESU analyzer sets up
the Fault condition. The ESU should alarm. Press
F4 PASS
or
F5 FAIL
to store
the test results.
The table beginning on the next page supplies specific information about the
tests for each autosequence.
