5.1 Function test
VEGASWING 71A and 75A are equipped
with an integrated test switch which can be
activated magnetically. Proceed as follows to
test the instrument:
• Make sure that the tuning fork is uncov-
ered.
• Hold the test magnet (accessory) to the
magnet symbol on the instrument housing
(see fig. 5.1). The test magnet simulates a
covering of the tuning fork. If the tuning
fork is uncovered, the signal lamp of
VEGASWING changes status. The elec-
tronics and the switching output of VEGAS-
WING are checked now.
Note that the connected instruments will be
activated during the test.
If, despite several tests with the test magnet,
VEGASWING 71A or 75A does not switch
over, check the plug connection and the
connection cable and test the instrument
again. If there is no switching function, the
electronics is defective. In this case you have
to replace the electronics (see "5.2 Replace-
ment of electronics") or send the instrument
to our repair department.
Note:
It is absolutely necessary that you remove
the test magnet after the test from the instru-
ment housing.
