6. Setting tests
The insulation tester MD-5075x is an extremely versatile instrument that
enables automatic performance of several types of insulation tests, and
records them in its internal memory and/or prints the results. Thus, it is
necessary to appropriately define the tests to be performed, setting the
following parameters before starting the measurement: Test voltage, Test
duration for “TIMER” mode test, Maximum Voltage for step voltage test
(SVT) and Minimum resistance limit for “Pass/ Fail” tests.
6.1. Test voltage definition
In order to define the test voltage value, first it is necessary to select one
of voltage adjustment keys:
. These keys enable both the
pre-programmed voltage selection ( ) and the and
keys which increase or decrease the value of the step voltage test for
25 V, 100 V or 500 V, depending on the selected voltage adjustment key.
As long as the equipment is on, the voltage adjustment key
will be
selected. Please, press again the adjustment key selected at the moment
with the aim of leaving the test voltage selection mode.
Note: Test voltage is the only one parameter that may be modified during
tests.
