5-8-2 Measurement Using an AC Clamp Probe (CL-20D)
Max. measuring current: 200 A AC
1) Applications: Sine-wave current of 50 to 60 Hz AC, such as the
current consumption of a home appliance or a power supply.
2) Measuring ranges: Two ranges including 20 A and 200 A.
3) Measuring procedure:
①
Connect the red plug of the clamp probe to the V input
terminal and the black plug to the COM input terminal.
②
Set the function switch to “ACV” and press the RANGE
HOLD button to select the 11 V range.
③ Set the range switch of the clamp probe to the 20 A or 200 A
range.
④
Open the clamp jaws of the clamp probe and clamp the
measuring target wire with it.
⑤
Multiply the reading by 10 when the 20 A range is selected
on the clamp probe or by 100 when the 200 A range is
selected.
⑥
After measurement, open the clamp jaws of the clamp probe
to release it from the measuring target wire.
● It is not possible to measure a current over 20 A or 200 A. (A
reading is displayed but it is not accurate.)
●
Clamp the measuring wire at the position as close to the
center of the clamp jaws as possible.
