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 0.1Ω ~ 0.2Ω. To test the
leads resistance, touch the probe tips together, for accuracy
measurement in low resistance.
