Measurement Operation(9)
G. AC Current Measurement
(see figure 9)
( figure 9)
Warning
To avoid electric shock, never measure current while
the test leads are inserted into the input terminals
and disconnect test leads and tested circuit connection.
Never attempt an in-circuit current measuremnet
where the open-circuit voltage between the circuit
and the ground is greater than 600V
Use proper function and range for the measurement.
The measuremnet ranges of current are: 2.000A, 20.00A,
200.0A and 400A.
To measure current, do the following:
1. Set the rotary switch to 2/20A or 200/400 A
2. Press the lever to open the transformer jaws.
3. Center the conductor within the transformer jaw.
The measured value shows on the display, it is a
effective value of sine wave (mean value response).
