5-6 Current Measurement (A)
1. Never apply voltage to the input terminals.
2. Be sure to make a series connection via load.
(See fig10, page14)
3. Do not apply an input exceeding the maximam rated current
to the input terminals.
WARNING
5-6-1
DC/AC μA・mA Measurement Maximum rating input value DC/AC 320mA
1) Applications
Current in DC and AC circuit is measured.
2) Measuring ranges
32μA〜320mA (5 range)
3) Measurement procedure (See fig11, page15)
①Connect the black plug of the current probe to the COM
input terminal and the red plug to the "μA ・mA" input
terminal.
②Select either current function, and select either DC● or AC
〜 with the shift switch.
③Apply the black test pin to the negative potential side of the
circuit to measure and the red test pin to the positive potential
side.
④Read the value on the display.
⑤After measurement, remove the red and black test pins from
the circuit measured.
●If the display will not change when an input signal is applied
(measurement is not possible), a probable cause is a blown fuse.
●The current ranges of 320μA to 3200μA and 32mA to 320mA
of this equipment are the auto ranges. The ranges can also be
fixed using the range hold switch.
●The accuracy guaranteed frequency range 40Hz to 400Hz
(CD731), 40Hz〜1kHz (CD751) .
●For the μA・mA range, no unit symbol will be indicated.
