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.
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).
