2. Current
measurement
1. Set the switch to
.
2. Select the type of signal, AC+DC, AC, or DC, by pressing
.
Depending on what you select, the screen displays AC, DC, or AC+DC.
3. Connect the black lead to the “COM” terminal and the red lead to “
A
”.
4. Place the test probes in series between the source and the load:
5 Read the measurement value indicated on the display unit.
“
O.L
” is displayed, if I
>
20A.
6 As default, the 2nd display unit indicates the frequency, except in DC.
Remark:
It is possible to activate the filter in A
AC+DC
, A
AC
.
The cutoff frequency of the filter is
≤
300Hz.
When a voltage having a frequency above 150Hz is
measured, it is heavily attenuated, and so a large error may
be observed. It is necessary in this case to deactivate the
filter to have the full bandwidth.
