9.6 Low Ohms Measurement 0 - 500Ω
- 11 -
Always check for voltage before testing and measuring on
a circuit. This instrument is intended for measuring Low Ω and
Insulation resistance on unenergized circuits only.
Use the procedure explained at points 9.2, 9.3, 9.4.
The first procedure to follow, is to zero the test leads and the fuse
resistance. The instrument is equipped with a Zero Ω Knob.
First, short circuit the test leads by connecting them together,
then, press the test button and adjust the zero Ω knob until the
pointer is precisely on the "0" of the 500Ω scale.
Use the mirror scale to be precise with the pointer.
Connect the test leads to the circuit to be measured.
For short test, press button and keep pressed.
For long test or hand free Measurements, press and turn
the test button.
