The test magnet changes the current switching condition of the

during the test.
If OPTISWITCH 4000 C does not switch over after several
tests with the test magnet, you have to check the plug
connection and the connection cable and test the instrument
again. If there is no switching function, the electronics will be
defective. In this case you have to exchange the electronics or
return the instrument to our repair department.
