Ac And Dc Voltage Measurements - Sonel CMP-401 Manual De Uso

Do not realise measurements if the battery compartment is
open.
Do not commence current measurements if the test leads
are connected 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 40A
400A~, if the range of the measured is not known, select the
highest range first,

press the REL button to zero the meter (in DC mode),

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.
