QUICK START

Refer to the next page for location of controls
Connect the test leads to the instrument + and – terminals and to the
item to be tested. Ensure the instrument battery is charged, or connect
to a suitable external supply. Press the 'On / Off' button and wait until
the word 'CAL' disappears from the display.
To carry out a test requires only three decisions:
1. What type of test do I want?
The options are Insulation Resistance (IR) or Polarisation Index (PI),
which are selected by briefly pressing the PI button to the left of
the display. If PI is selected the 'PI Test' indicator at the top of the
display will illuminate. If IR is selected the 'PI Test' indicator will
be blank.
2. What test voltage do I want?
Use the 'Test Voltage increase / decrease' buttons to the left of
the display to adjust the test voltage up or down until the required
value is shown in the 'Voltage Indicator', top left of the display.
3. Do I wish the automatic timer to control the test?
Adjust the test duration using the 'Test Duration increase /
decrease' buttons to increase or decrease the test time, which can
be seen in the 'Time Indicator' display. If a valid time has been
selected the 'Timer On' indicator will light. Selecting 00:00 turns
the timer off.
If PI has been selected as the test type the timer will default to 10
minutes since a PI test takes 10 minutes. However, you may adjust the
test time so that the test continues after the 10-minute duration by using
the 'Timer Adjust' keys as above. The 'Timer On' indicator will light.
Press the 'Test Start / Stop' button for at least one second to start the
test. The 'Voltage at Terminals' arrows flash and the 'HT On' l.e.d.
flashes red to signify that the test is running. During the test the test
voltage at the instrument terminals will appear in the 'Voltage
Indicator' and the elapsed time will appear in the 'Time Indicator'.
The measured value of resistance will appear in both analogue and
digital displays. You can stop the test at any time by pressing the 'Test
Start / Stop' button, or the test will stop automatically after the preset
test time. The item under test will be automatically discharged to a safe
level and the final measured values will be shown on the display.
Return to the initial screen by pressing any of the 'Voltage Adjust' or
'Time Adjust' buttons briefly.
