operator is alerted by a message.
- The test is started pressing the START pushbutton, and then also pushing the multifunction knob.
- During the test, the circuits driving the coils give alarm messages in case of: selected current range
exceeded (short circuit included); coil driver over-temperature.
- During the test, if the trigger criteria (coil current, auxiliary input, analog input) is not met within
the maximum test time, the test set displays a warning message.
- The 5 V transducer supply is protected against short circuit on the output, and against contact with
a voltage up to ± 500 V. In both instances, the circuit is not damaged.
- All inputs and outputs are isolated between them.
