Zero Adjustment
As the voltage offset and temperature drift might affect the position
of the baseline of the current probe, perform zero adjustment after
performing demagnetizing when beginning measurements.
1. Turn the zero adjustment dial on the terminator to adjust the
baseline to the zero position.
2. When adjustment is not possible within the range of zero
adjustment dial, use a nonconductive screwdriver to (such as
ceramic screwdriver) to adjust the baseline to the adjustable
range of the zero adjustment dial via the coarse adjustment
trimmer; then, use the zero adjustment dial to adjust the
baseline to the zero position (only applicable to RP1003C and
RP1004C).
Measurement Steps
Make measurements after the above operations are finished.
1. Open the current sensor by pushing the slide switch in the
direction of the arrow as shown in the figure below (for
RP1003C and RP1004C, the slide switch should be at the
OPEN position; for RP1005C, UNLOCK should be displayed on
the slide switch and LOCK should disappear).
