5. Test procedure
Testing is only allowed under observation of the
"Notes on safe operation"
for the relevant DC
voltage detector (see point 4.4, page 7).
5.1 Functional test
A functional test must be performed before verifying the absence of voltage (dead condition).
When pressing the "TEST" button (see Fig. 3), the indicator is switched on and is checked for
proper operation (check of the response threshold).
When pressing the "TEST" button , the red light " " illuminates. As soon as the "TEST" button is
released, the green light " 0 " lights up. The voltage detector is ready for testing (ready for operation
for approximately 40 to 60 seconds).
If the functional test cannot be performed properly, the batteries and/or lamps should be replaced
(see 6.1 and 6.2). After that, the functional test should be repeated. If there is still no clear
indication, the voltage detector should be withdrawn from service immediately and sent to
DEHN + SÖHNE for repair.
Indication of low batteries
If both lamps light up after releasing the "TEST" button , the battery is low. The voltage detector
is no longer ready for testing. New batteries must be inserted.
