4. Resistance measurement (2W, 4W, LP-2W, and LP-4W)
1. Press .
The resistance is measured by using the 2W or 4W which is set before this
measurement.
2. Press and .
The resistance is measured in low-power in which the measurement current is
reduced.
3. Press and to return to the 2W and 4W measurement.
4. Press .
The 2W and 4W are switched alternately.
NOTE: In the following measurement ranges, the LO terminal of 4W SENSE does
not recognize the voltage and operates as in 2W measurement.
7461A: 1000 k range or more in 4W, 100 k range or more in
LP-4W
7451A: 3000 k range or more in 4W, 300 k range or more in
LP-4W
