At current measurement, according to the size of internal
resistance of the current range, measuring value will be
smaller than actual current.
1) Application
Current in batteries or DC circuit is measured.
2) Measuring range: 30 µ/0.3 m/3 m/30 m/0.3 A (5ranges)
3) Measurement procedure
①
Shift the polarity reversal switch to
+
position.
②
Connect the black plug of the test lead to the
−
input
terminal and the red plug to the
+
input terminal.
③
Set the function/range selector to an appropriate DCA
range.
④
Apply the black test pin to the negative potential side of the
circuit to measure and the red test pin to the positive
potential side.
⑤
Read the pointer on V
・
A scale.
⑥
After measurement, remove the red and black test pins from
the circuit measured.
6-5 DCA Measurement ( ): Max. measuremet value 0.3 ADC
1. Never apply voltage to
the input terminals.
2. Be sure to make a series
connection via load.
3. Do not apply an input
exceeding the maximum
rated current to the input
terminals.
