5.8 Current measurement
WARNING
To avoid the electric shock, the device must not be
connected to circuits in which the measuring voltage
exceeds 1000 V.
CAUTION!
Do not make current measurements of 10 A for longer than
30 seconds. Exceeding this time may cause damage to the
meter and/or test leads. When the current of 10 A, the in-
terval between successive tests should be approx. 15 mi-
nutes.
5.8.1 The range of 10 A
To perform the current measurement:
set the rotary switch at
10A
,
press
MODE
button to display the following symbols on the
display:
, if you are measuring Alternating Current,
, if you are measuring Direct Current,
connect black test lead to

disconnect the power supply from the tested circuit and then con-
nect the meter in series (for
DC
circuits: connect the red probe to
the positive pole),
turn on the power supply of the circuit,
read the measurement result on the display.
5.8.2
Range of mA, µA
To perform the current measurement:
set the rotary switch at
mA
or
