Resistance Measurements - Sonel CMP-401 Manual De Uso


connect the red test lead to socket V/Ω/CAP/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,

having done the measurement disconnect the test leads from
the meter.

Resistance measurements

Measurements must not be realised in live circuits. Capaci-
tors must be discharged.
Do not realise measurements if the battery compartment is
open.
In order to realise a measurement of the resistance it is neces-
sary to realise the following actions:

place the rotational selector in the position Ω

connect the red test lead to sockets V/Ω/CAP/TEMP and the
black one to sockets COM,

make sure symbol
the case of shorted terminals of the measurement probes the
display shows „0",

with the RANGE button set the measurement range manually
if necessary,

touch the test probe tips across the circuit or component under
test; it is best to disconnect one side of the device under test
so the rest of the circuit will not interfere with the resistance
reading,

read the result of the measurement on the display,
