To Measure Resistance
Range: 200 Ω, 2 kΩ, 20 kΩ, 200 kΩ, 1 MΩ, 10 MΩ, 100 MΩ
Max Resolution: 100 μΩ (in 200 Ω range)
Input Protection: a 1000 V input protection is available in all ranges. 10%
overrange is available on all ranges.
DM3068 provides 2-wire (2WR) and 4-wire (4WR) resistance measurements.
When the measured resistance is lower than 100 kΩ, the 4-wire resistance
measurement is recommended to reduce the measurement error caused by test
lead resistance and contact resistance between the probe and the testing point
because these two resistances cannot be ignored any more, compared to the
measured resistance.
Operating Steps:
1. Enable the 2WR/4WR measurement
Press
at the front panel to select 2WR (2-wire resistance)/4WR (4-wire
resistance) measurement and to enter the following interface.
2. Make connection
Connect the test lead with the measured resistance by referring to
“Measurement Connections”.
3. Set the range and resolution
Specify an appropriate range and resolution according to the measured signal
and measurement requirements.
