Warning!
To avoid damages to the Meter or to the devices under test, disconnect circuit power and
discharge all the high-voltage capacitors before measuring resistance.
The resistance ranges has 7 measurement positions on the rotary switch: 200Ω, 2kΩ, 20kΩ,
200kΩ, 2MΩ, 20MΩand 200MΩ.
To measure resistance, connect the Meter as follows:
1. Insert the red test lead into the
terminal.
2. Set the rotary switch to an appropriate measurement position in Ω range.
3. Connect the test leads across with the objet being measured. The measured value shows on
the display.
Note
• The test leads can add 0.1Ω to 0.3Ω of error to the resistance measurement. To obtain
precision readings in low-resistance, that is the range of 200Ω, short-circuit the input terminals
beforehand and record the reading obtained (called this reading as X). (X) is the additional
resistance from the test lead.
• Then use the equation:
measured resistance value (Y) (X) = precision readings of resistance.
• For high resistance (>1MΩ), it is normal taking several seconds to obtain a stable reading.
• When there is no input, for example in open circuit condition, the Meter displays "1".
When resistance measurement has been completed, disconnect the connection between the
testing leads and the circuit under test.
