Model UT201/202: OPERATING MANUAL

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).
