7. Other functions
7.1. 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 key again.
7.2. 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.
7.3. True RMS AC/DC Voltmeter
In order to use this function, connect the test points and turn on MD5KVR.
The measured value will be exhibited automatically in the display.
AC
15 V up to 1000 Vr.m.s.
Precision: ± (5% of the reading + 3 digits)
7.4. 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 3,000 µA, with a
Precision of ± (10% of the reading + 3 digits).
7.5. Hold
This function allows holding the last performed reading on the display at
the moment when pressing the
When this key is pressed again, the equipment updates the resistance
DC
15 V up to 1000 V
key, without interrupting the test.
