A
DANGER
Never apply voltage to test leads and SENSE terminal when the
Resistance, Low-power resistance or Continuity Check are selected.
Doing so may damage the product and result in personal injury.
To avoid electrical accidents, remove power from the circuit before
measuring.

L9170-10 TEST LEAD
NOTE
When measuring high resistance, there are cases in which an overload ( “ OF ”
displayed) occurs owing to external noise. Do not use the unit near fluorescent light
or power line.
When external noise is high, please shield the red lead (connected to the V
Ω
CLAMP terminal) and the sample to be measured. Connect the outer shield cover to the
COM terminal. (Or use a shielded line, such as the 9326 CONNECTION CORD.)
In case of using a dial resistor, connect the GUARD terminal to the COM terminal
of the unit.
3.2.1 Resistance Measurement (2-Terminal)
3.2 2-Terminal Resistance Measurement
Check to make sure that the black lead of
the L9170-10 TEST LEAD is connected
to the COM terminal and the red lead to
the V Ω CLAMP terminal.
