7. How to perform tests
After having set the desired measurement, press
key. The HIGH VOLTAGE indicator will turn
on indicating that the insulation tester is applying
high voltage to the element under test.
During some seconds the intelligent auto-range system will search for the
most convenient range for the value under measure. At this moment the
display will show the message “
WAIT... ”.
As soon as the
MD-5075x selects the appropriate range, the display will
show the number of test, the selected voltage value, exhibiting the value
of the applied voltage and the leakage current, date and time, will start
counting the elapsed time and the resistance value indication will be
exhibited with its corresponding unit, and the analogue indication will start
by bargraph. In order to end the test, press the key. At that moment,
last measured values will remain frozen in the MD-5075x display. By
pressing the key again, the equipment will return to the voltmeter
function.
