8. Other functions

8.1. Backlight

The equipment display has a backlight. In order to activate it, press
key. After 10 seconds the backlight will auto-turn off. If you want to
reactivate it, press

8.2. Filter

When insulation measurements are carried out in transformers or in large
dimension machines, in presence of strong electromagnetic fields, it is
possible for the equipment reading to be unstable, especially for
resistance values higher than 100 MΩ. In these cases it is convenient to

press the key before starting the measurement activating the filter
which allows for the reaching of the insulation resistance value in an
upward curve without significant oscillation.

8.3. True RMS AC/DC Voltmeter

In order to use this function, connect the test points and turn on
MD-10KVx. The measured value will be exhibited automatically in the
display.
AC
15 V up to 600 V r.m.s. 15 V up to 600 V
Precision: ± (5% of the reading + 3 digits)

8.4. Leakage current measurement

During the tests, the equipment measures and exhibits in the display the
leakage current value within a range of 1 nA up to 1500 µA, with a
Precision of ± (10% of the reading + 3 digits).
