Simple Maintenance:
There is no maintenance required. There is no calibration procedure
(no potentiometers to turn). This is due to the utilization of high precision components in the
design.
Advanced Protection:
Upon powering on the system initializes itself with a self-calibrating,
circuit checking sequence. If any problems are detected during this initialization period, or
during operation, the operator is immediately notified. The system constantly monitors the
condition of the transformer under test. The TR-MARK III can even recognize shorted leads
and will terminate the test without any damage to the test equipment. This works especially
well when test leads accidentally fall free from the transformer while under full voltage
measurement. Accidental interchanging of the test leads on the High and Low voltage side
are also detected and the measurement is safely halted
