Here you can set the voltage using the voltage up and down in steps of 10V below 1000V
and in steps of 25V above 1000V. There is also a standard voltage button to set standard
testing voltages (100V, 250V, 500V, 1000V, 2500V, 5000V).
You can also change the filter settings in this window (hardware and software filter).
These filters are very useful in noisy environments. The software filter can be selected
from the drop down list which will appear after pressing the software filter button.
As we know DAR tests are measurements of resistance over time expressed as a ratio
of resistance at time t2 divided by resistance at time t1. The t1 and t2 both can be set in
the control window with the help of their corresponding arrows. The up arrow will
increase the time and the down arrow will decrease the time.
After setting up all the basic settings press the button to go back to the main
measurement screen. All these control settings are stored by the meter so that the next
time you start the meter you do not need to do these settings again.
Then connect the test leads to the equipment whose Insulation Resistance has to be
measured.
On the measurement screen press and hold the button for about 3 seconds and
then release it to start the test.
The speaker will give 3 beeps in order to indicate that the test has started. After the test
has been completed all the parameters will be displayed(according to the meter setting)
like insulation resistance, capacitance, DAR, PI, voltage, current.
