Note:
• Before measuring resistance, switch off the power supply of the circuit, and fully
discharge all capacitors.
• If the resistance when probes are shorted is more than 0.5
Ω
, please check if test leads
are loosened or damaged.
• If the resistor is open or over the range, the "OL" symbol will be displayed on the
screen.
• When measuring low resistance, the test leads will produce 0.1

error. To obtain accurate measurement, the measured value should subtract the value
displayed when two test leads are shorted.
• When measuring high resistance above 1 M
Ω
, it is normal to take a few seconds to
steady the readings. In order to quickly obtain steady data, use short test wires to
measure high resistance.
