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 (250V, 500V, 1000V, 2500V, 5000V).
You can also change the filter settings in this window (hardware filter). This filter is very
useful in noisy environments.
You can also set the test time in this mode by pressing the second or minute button.
The keyboard will appear and then you can enter the desired time between 2 min 30
sec and 99 min 59 sec and then press the button on the keyboard to set the time.
Please note that the number of seconds entered should be a multiple of 5 or the
meter will modify it to a value which is divisible by 5.
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 like insulation resistance in all
the 5 intervals(for last interval it is the value on the main display) and also the current and
voltage values for each interval are displayed.
Because there are a lot of parameters to be displayed they have been divided into three
sub screens which can be scrolled using the scrolling arrows. Figure(on next page) shows
the sequence of the screens along with the parameters displayed on the corresponding
screen.
You can save the data of this test by pressing the button. After pressing this button
a message will appear to tell you about the file number. You can press the OK button on
the message box in order to go back to the measurement screen.
