G. AC Current Measurement
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 measurement
where the open-circuit voltage between the circuit
and the ground is greater than 250V.
Use proper function and range for the measurement.
The measurement ranges of current are: 2.000A, 20.00A,
200.0A and 600A.
To measure current, proceed as follows:
1. Set the rotary switch to 2/20A
~
or 200/600A
~
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).

Note
• To obtain accurate reading, measure only one
conductor at each time.
• When current measurement has been completed,
disconnect the connection between the conductor
under test and the jaw, and remove the conductor
away from the transformer jaw of the Meter.
SLEEP MODE
To preserve battery life, the Meter automatically turns off
if you don´t turn the rotary switch or press any
button for around 15 minutes.
The Meter can be activated by turning the rotary switch or
pressing any button with the following conditions:
1. Turn the rotary switch into any position.
2. Press one of the
SELECT
,
MAX
or
HOLD
buttons.
To disable the SLEEP MODE function, press and hold
HOLD
button while turning on the Meter.
