Measuring Resistance

To avoid harms to you, do not attempt to input
voltages higher than 60V DC or 30V rms AC.
To avoid damages to the Meter or to the
devices under test, disconnect circuit power and
discharge all the high-voltage capacitors before
The resistance ranges are: 200 Ω , 2 kΩ, 20 kΩ, 200kΩ,
2 MΩ and 20 MΩ.
To measure resistance,
connect the Meter as
follows:
1. Insert the red test lead
into the V Ω terminal
and the black test lead
into the COM terminal.
2. Set the rotary switch

measured value shows on the display.
Note:
The test leads can add 0.1Ω to 0.3Ω of error to resistance
measurement.
• For high-resistance measurement (>1MΩ), it is normal taking
several seconds to obtain a stable reading.
• If reading with shorted test leads is not ≤0.5Ω, check for loose
test leads, wrong function selected, or enabled data hold
function.
• The LCD displays OL indicating open-circuit or the tested
resistor value is higher than the maximum range of the Meter.
• Resistance measurement is default to auto range mode.
• To remove the objects being tested from the circuit when
measuring can obtain a more accurate result.
• When resistance measurement has been completed,
disconnect the connection between the testing leads and the
circuit under test and remove testing leads from the input
terminals.
