2.1 Measurement Procedure
12
5.
Clamp the conductor to be measured and close the
clamp.
6.
Press on the slider until it clicks to lock shut.
Press the sensor slider until the "UNLOCK" message dis-
appears and "LOCK" is displayed, and confirm that the
slider is firmly locked and the clamp securely closed.
7.
Monitor noise current.
The output rate of this device is 0.1 V/A. When using a
general purpose waveform monitoring instrument, derive
the current sensitivity from the voltage sensitivity. For
example, if the waveform measurement instrument's volt-
age sensitivity is 100 mV/division, the current sensitivity
is 1 A/division.
Make sure that the cur-
rent direction indicator ar-
row matches the direction
of current flow on the con-
ductor being measured.
Make sure also that the
conductor is clamped in
the center of the clamp
opening.
