Measuring Resistance
Caution
To avoid possible damage to the Meter or to the equip-
ment under test, disconnect circuit power and discharge
all high-voltage capacitors before measuring resistance.
Note –
The Meter provides an open voltage
≦
–1.5V to the
circuit under test that causes the diode, transistor junction to
conduct so
it is better to disconnect the resistance from the
circuit to get a correct measurement.
The resistance of test leads is about 0.1
Ω
~ 0.2
Ω
. To test the
leads resistance, touch the probe tips together, for accuracy
measurement in low resistance.
