7. Other functions
7.1. Filter
When insulation measures are carried out in transformers or in large
dimension machines, in presence of strong electromagnetic fields, it is
possible that the equipment reading is unstable, especially for resistance
values higher than 100 M . In these cases it is convenient to press the
key before starting the measurement. This function allows to reach
the insulation resistance value in an upward curve without significant
oscillations.
7.2. Voltmeter
By pressing the key, the equipment will measure the voltage
effectively applied to the element being tested.
7.3. Hold
The key allows to hold the last performed reading on the display, at
the moment this key was pressed, without interrupting the test. When this
key is pressed again, the equipment updates the resistance and time
values. The key led and the letter H on the display indicates that the
function was activated.
