NOTE: Input signal level must be higher than 0.5V (it is sensitivity).

5-5. DC/AC µA or mA measurement

DC Current range is 200.0µA/2000µA and 20.00mA,/200.0mA and then 10A

range.

AC Current range is 200.0µA/2000µA and 20.00mA,/200.0mA and then 10A

range.

① Turn off power to the circuit. Set the rotary switch to the proper

DC/AC µA or DC/AC mA position.

② Break the current path to be tested. Connect the red test lead to the

more positive side of the break and the black test lead to the more

② The measuring procedure is same as that of 5-5 section..

Note:

● For safety's sake, the measuring time for high current should be ≤10 second

for each measurement and the interval time between two measurement should

be greater than 5 minutes.

● When current measurement has been completed, disconnect the connection

between the testing lead and the circuit under test.
