3. Connect the test lead
and measure
Connect the test lead between the A
and COM port or LO to COM port,
depending on the current. For current ≤
2A use the LO port; For current up to
10A use the A port. The display
updates the reading.

2-11. 2W/4W Resistance Measurement
Measurement type
2-wire
Uses the standard V-COM ports.
Recommended for measuring resistances larger than 1kΩ.
4-wire
Compensates the test lead effect using the 4W compensation
ports, in addition to the standard V-COM ports.
Recommended for measuring sensitive resistances smaller
than 1kΩ.
1. Activate resistance
measurement
For 2-wire resistance measurement, press the
2W/4W key once.
For 4-wire resistance measurement, press the
2W/4W key twice.
2. 2W resistance mode

3. Connect the test lead
and measure
Connect the test lead. For 2-wire res
istance, use the Ω (V) and the COM port.
For 4-
wire resistance, use the Ω (V) and the COM port, plus the 4W sense, and
LO port for sensing. The display updates the reading.
