Continuity Check (

1) What to measure
・
(Continuity check): Wiring connections, Op eration of
switches, etc.
2) Measuring ranges
・
: Beeper threshold level: between 20
Ω
and 300
Ω
Response time: < 100
µ
s
* Open circuit voltage between the measuring terminals: < 1.2V dc
3) Measuring procedure
①
Connect the red plug of the test lead to
measuring terminal
and the black one to the COM terminal.
②
Set the function selector to
.
③
Apply the test pins (Red and Black) to the object to measure.
④
A continuous beep tone indicates a complete wire.
(The LCD display indicates the measured resistance at the time.)
Do not apply any voltage or current to the measuring terminals.
In the case of high resistance measurement, readings may be
unstable due to external inductive influence.
CAUTION
WARNING
Note:
To avoid external noise influence, shield the object to measure with
COM potential. Measurements with finger-touched test pins may
cause some errors being influenced by human body conductance.
