This device is a detector. The indications it provides must
not be used for measurement purposes.
2.1. SELF-TEST
Before using the C.A 760N, perform a self-test. This checks
the integrity of the leads, the proper operation of the elec-
tronic circuit, and the battery voltage.
Connect the red test probe to the + terminal and the black
lead to the COM terminal.
Touch the 2 test probes together and press the AUTO TEST
button. Press for as long as necessary.
If all of the indicators of the device except ELV light and
the audible signal sound, the device is working properly
and can be used.
If every other indicator lights, the batteries must be replaced
(see §4.2).
