1. Never apply voltage to the input terminals.
2. Be sure to make a series connection via load.
(please see to above drawing)
3. Do not apply an input exceeding the maximum rated current
to the input terminals.
5-7 Current Measurement ( A, mA, A)
5-7-1 Current Measurement ( A, mA)
Maximum rating input value DC/AC 4000 A 400mA
1) Applications
Current in DC and AC circuit is measured.
2) Measuring ranges

3) Measurement procedure (See Fig 13, page 16)
①
Connect the black plug of the test lead to the COM input
terminal and the red plug to the input terminal.
②
Set the function switch at "400 4000 A" or "40 400mA" function.
③
Select the select switch at " " (DC) or " " (AC).
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.
