5-10-1 Current (mA/μA) measurement
(m , m , m , μ , μ , μ Max. rated input current 600mA dc/ac)
1) What to measure
・
m , μ (DC current): DC circuit current
・
m , μ (AC current): AC circuit current
・
m /m , μ /μ (DC current component/AC current component)
・
m /m , μ /μ (DC/AC superimposed signal current/AC current
component)
・
Hz (Frequency): Measuring current frequency
2) Measuring ranges
mA : 60.00mA and 600.0mA
μA : 600.0μA and 6000μA
3) Measuring procedure
①
Connect the red plug of the test lead to measuring
terminal and the black one to the COM terminal.
②
Set the function selector to or , then press the
SELECT button to select [m ], [m /m ], [m /m ],
[m / Hz] for mA range , or select [μ [μ /μ ], [μ /μ ],
[μ /Hz] for μA range.
③
Connect the test pins (red and black) in series with the circuit
to measure.
・
m ,μ : Connect the black test pin to the lower electric
potential side of the circuit to measure, and the red test pin
to the higher electric potential side in series with the object.
・
m /μ
、
m /μ : Connect the test pins (red and black) in
series with the circuit to measure.
④
Read the display.
