How are the various quantities measured? (continued)
with a current
clamp
1. Press:
.
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 of the clamp to the "
COM
" terminal and the red lead of
the clamp to "
V
".
4. Select the transformation ratio (the same as that of the clamp) - 1mV/A,
10mV/A, 100mV/A, or 1000mV/A - by pressing on "clamp" (
) to have a
direct reading of the current.
5. Place the clamp around the conductor:
7.
Read the measurement value indicated on the display unit.
The
measurement accuracy is indicated in "Technical characteristics",
§. "Clamp" p. 46.
8. As default, the 2
nd
display unit indicates the transformation ratio in mV/A.

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 passband.
