Probe Holder
The Meter is equipped with a probe holder that can either hold a test
probe or can be used to attach the Fluke ToolPak. See Figure 5.

Taking Measurements
XW Warning
To prevent possible electric shock, fire, or personal injury,
do not use the clamp on non-insulated conductors.
Measurements can be taken with the clamp in the docked position,
remotely using the 1 m cable, or via test leads. For accurate
measurements:
• Always zero the Meter prior to taking measurements with the clamp.
• To reduce magnetic influences, zero the Meter as close to the
measurement in the same position or jaw direction that is used for
the measurements as possible.
• Make sure the clamp is free of contamination.
To use the clamp for measurements:
1. Press C to enter Clamp Measure mode and to zero the Meter.
Clamp mode includes clamp measure, mA scale output, and mA
IN/OUT. If necessary, press N to change to mA scale.
2. Clamp the jaw around the conductor under test. The Meter displays
the measured conductor current. See Figure 6.
• A positive reading indicates current flowing in the direction of
the arrow on the clamp.
• A negative reading indicates current flowing in the opposite
direction of the arrow.
• Do not clamp more than one wire.
The small secondary display shows the reading in mA percentage of
span.
