AC/DC Current Measurement
Current is measured via the current clamp of the device. You can
do measurements of insulated and non-insulated conductors.
Always disconnect the probes before measuring current.
1. Turn the rotary switch to and select the appropriate range
(60A or 600A). Then select either the AC or the DC current
function with the "Z/F" button.
2. Press the clamp release trigger and open the clamp. Now
grasp the conductor to be measured and close the clamp
through the leaver. Ensure to position the conductor in the
middle between the 2 positioning markings on the pliers.
WARNING: do not surround more than 1 conductor. If the
supply and return conductors (e.g. L & N) are measured, they
will cancel each other out and no result is displayed. Measure
them separately. If they are together in one cable, use a cable
separator to measure the conductors separately.
3. The results will be shown on the display. If the measured
current is >3A, the orange backlight of the display will turn on.
4. During AC current measurement, press the “Z/F” button to
display the frequency value or to switch to the LPF function.
