5-11-1 AC flexible clamp sensor: CL3000
(Max. measurable current 3000 A ac)
1) What to measure
50/60 Hz sine wave current such as consumption current of
home appliances, current of power supply equipments, and etc.
2) Measuring ranges
30 A, 300 A, and 3000 A
3) Measuring procedure
①
Connect the red plug of the current probe to the V measuring
terminal and the black one to the COM terminal.
②
Set the function selector to , then press the SELECT
button to select /Hz.
③
Press the RANGE button to set the 9.999 V range.
④
Set the range selector knob on the current probe to the 30 A,
300 A, or 3000 A range.
⑤
Clamp the conductor under test with the flexible current
probe.
⑥
Multiply the reading by 10 for 30 A range, by 100 for 300 A
range, and by 1000 for 3000 A range respectively, and read
in units of A (amps).
Note:
・
Current exceeding 30 A, 300 A, or 3000 A cannot be measured.
(Do not measure such high current even though the display
works.)
・
Try to put the conductor under test in the center of the flexible
current probe as possible.
5-11-2 Clamp probe: CL-22AD
(Max. measurable current 200 A dc/ac)
1) What to measure
ACA: 50/60 Hz sine wave current such as consumption current
of home appliances, current of power supply equipments,
and etc.
DCA: Current of automotive electric circuits, consumption
current of DC equipments, etc.
2) Measuring ranges
20 A and 200 A
3) Measuring procedure
①
Connect the red plug of the current probe to the V measuring
terminal and the black one to the COM terminal.
②
To make DC current measurement (DCA), set the function
selector to and press the SELECT button to select
m , then press the RABGE button to set 600.0 mV range.
To make AC current measurement (ACA), set the function
selector to
and press the SELECT button to select m
/Hz, then press the RANGE button to set 600.0 mV range.
③
Set the range selector knob on the current probe to the 20 A
range or 200 A range.
*Before making DC current measurement, turn the Center
Adjuster knob to make the reading zero.
④
Open the clamp jaws of the clamp probe and clamp the wire
to measure.
⑤
Multiply the reading by 0.1 for 20 A range, and read the
display directly for 200 A range.
Note:
・
Current exceeding 20 A or 200 A cannot be measured.
(Do not measure such high current even though the display
works.)
・
Try to put the wire to measure in the center of the clamp jaws
as possible.
