5-10-2 Clamp probe: CL-22AD
(Max. measurable current 200A 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
20A and 200A
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 RANGE button to set 600.0mV 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 600.0mV range.
③
Set the range selector knob on the current probe to the 20A
range or 200A 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 20A range, and read the
display directly for 200A range.
Note:
・
Current exceeding 20A or 200A 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.
5-10-3 DC Clamp probe: CL-33D
(Max. measurable current 300A dc)
1) What to measure
Current of automotive electric circuits, consumption current of
DC equipments, etc.
2) Measuring ranges
30A and 300A
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 and press the SELECT
button to select m , then press the RANGE button to set
600.0mV range.
③
Set the range selector knob on the current probe to the 30A
range or 300A 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 30A range, and read the
display directly for 300A range.
Note:
・
Current exceeding 30A or 300A 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.
