Refer to Safety Warnings before using the instrument
Preliminary Test lead check
1.
Before each use of the instrument, visually inspect the test leads, prods
and crocodile clips to confirm that their condition is good, with no damaged
or broken insulation.
2.
Check continuity of the test leads by firmly shorting the leads together
and read the test lead resistance. measurement directly from the display.
Backlight operation
1.
Turn the instrument backlight 'On' by selecting the
2.
When the backlight is activated, select the desired test position.
3.
On completion, select the 'OFF' position to de-activate the backlight and
conserve battery life.
Continuity Testing
Turn the instrument 'On' by selecting the Ω range.
1.
2.
If required, zero test lead resistance by firmly shorting both leads together,
wait for the reading to stabilise and press the test button. Display of the
symbol confirms lead zeroing. Note: Lead zeroing cancels each time
the instrument is switched off, or Auto shut off operates.
3.
Connect the test probes to the isolated circuit under test.
4.
The display shows the resistance value. (Maximum 99,9Ω)
5.
On completion switch to 'OFF' position. Alternatively auto shut off operates
after 5 minutes of instrument inactivity.
Continuity Beeper
sounds when the test leads make contact with resistance less than 5Ω. Ιf
contact is maintained, beeping ceases after a few seconds and the resistance
value is displayed. Resistance greater than 5Ω is indicated by an intermittent
beep note.
