Performing resistance measurements
Measuring resistance
– Seven ranges:
– Slow reading rate: 120.000 Ω, 1.20000 kΩ, 12.0000 kΩ, 120.000 kΩ,
1.20000 MΩ, 12.0000 MΩ, 120.000 MΩ
– Medium reading rate: 400.00 Ω, 4.0000 kΩ, 40.000 kΩ, 400.00 kΩ,
4.0000 MΩ, 40.000 MΩ, 300.00 MΩ
– Fast reading rate: 400.0 Ω, 4.000 kΩ, 40.00 kΩ, 400.0 kΩ, 4.000 MΩ,
40.00 MΩ, 300.0 MΩ
– Measurement method: 2-wire ohms or 4-wire ohms, open circuit voltage
limited to < +9 V
– Input protection: 500 V on all ranges
1 Press . The default function is 2-wire Ω
measurement.
2 Connect the red and black test leads to the input terminal as shown in
Figure 1-15 or Figure 1-16 on page 41 respectively (according to the selected
measurement method).
3 Probe the test points (by shunting the resistor) and read the display. In
auto-ranging mode, the multimeter automatically selects the appropriate
range and the measurement is displayed.
Disconnect circuit power and discharge all high-voltage capacitors before
measuring resistance to avoid damaging the multimeter or the device under
test.
