Hands Free Insulation testing
To enable the hands free feature simply press the HANDS FREE button once, The
‘HANDSFREE’ annunciator will appear ashing on the LCD and will continue to do so
until cancelled by a further press of the HANDS FREE button or by changing the function
selector switch.
When the HANDSFREE annunciator is ashing a single press of the Orange test button will
toggle continuous testing on and off.
Once started a steady beeping tone will be emitted to indicate that measurement is being
taken.
After a second or two the test result will be displayed in the primary display area and an
audible tone will indicate either by a single beep that the result is a value above 2M
Ω or by
a short 2-tone alarm that the result is a value under 2M
Ω. The secondary display area will
show the terminal voltage being applied.
The tester will continue to take measurements and any further change to the resistance of
the circuit will be indicated by an audible tone as described above and a change of result
on the display.
Whilst testing in hands free mode continues the Red warning LED will ash to warn of the
voltage between the prod tips/crocodile clips.
A further single press of the test button will suspend measurement.
