Ac And Dc Voltage Measurements - Sonel CMP-400 Manual De Uso

Do not commence measurements if the test leads are con-
nected to the meter.
In order to realise a measurement of alternative current, it is
necessary to realise the following actions:

Set the Function switch to the 400A~ or 40A~ or 4A~ range, if
the range of the measured is not known, select the highest
range first,

open the clamp and place it on a single cable,

read the result of the measurement on the display,

move to the lower range if necessary.
During measurements of the current make sure the clamp is
properly placed. Otherwise the results of the measurements
will not be exact. The most exact result we will get if the wire
is placed in the middle of clamp.

AC and DC voltage measurements

In order to realise a measurement of AC or DC voltage, it is
necessary to realise the following actions:

set the function switch to the V

select AC or DC with the MODE button,

with the RANGE button set the measurement range manually
if necessary,

connect the red test lead to socket V/Ω/TEMP and the black
one to socket COM,

place the edges of the probes to the measurement points;
while measuring DC voltage place the red probe to the point of
higher potential,

read the result of the measurement on the display,
