3.3 How it Works
VOLTAGE MEASUREMENTS
Ensure the
TEST
button is released.
Insert the red test lead in
V
Ω
, and the black lead in
COM
. Connect
the red and black leads across the circuit to be measured - the
measured voltage will be displayed.
When a voltage higher than 30V is detected, the buzzer sounds
and the high voltage indicator (
) will blink in the upper-right
corner of the display.
ZERO KEY
When measuring low resistances, using the
)))
and
40
Ω
ranges,
compensation for the resistance of the test leads is needed:
Set rotary switch to desired low resistance range, short test leads
by holding them together or, if using croc clips, clipping them
together. Press and hold / latch the
TEST
button, the resistance of
the leads will be displayed, then press the
ZERO
soft key to carry
out the compensation; a triangle is shown in the middle of the
display. Press the
ZERO
soft key again to remove the
compensation.
CONTINUITY MEASUREMENT
Ensure circuit is not live by taking a voltage measurement
Set rotary switch to
40
Ω
range. Insert red test lead in
V
Ω
, and
black lead in
COM
. Connect the red and black leads to the circuit
to be measured and press the
TEST
button. The measured
resistance will be displayed. If
OL
is displayed this indicates the
resistance being measured is greater than the continuity range of
the tester.
4.4 Storage Conditions
The instrument should be kept in warm dry conditions away from
direct sources of heat or sunlight, and in such a manner as to
preserve the working life of the unit. It is strongly advised that the
unit is not kept in a tool box where other tools may damage it.
