Temperature Measurement - Sonel CMM-30 Manual De Uso


, if you are measuring Direct Current,
 connect black test lead to COM terminal, and red test lead to
VΩHz%
 disconnect the power supply from the tested circuit and then con-
nect the meter in series (for DC circuits: connect the red probe to
the positive pole),
 turn on the power supply of the circuit,
 read the measurement result on the display.

5.9 Temperature Measurement

To perform the measurement:

set the rotary switch at ºC
ºF,

to change the unit, press
MODE ,

place the adapter of the
temperature probe in
COM terminal (black leg)
and
VΩHz%
(red leg):

place the temperature
probe in the adapter, as
shown in the figure:
 thin pin of the probe
(marked as +) fits to
terminal +;
 thick pin of the probe (marked as K) fits to terminal –;
 reversed connection of the probe is mechanically
impossible,

contact the head of the temperature probe to the device under
test. Maintain the contact of the probe head with the part of the
device under test, until the reading stabilizes.

read the measurement result on the display,

after completing the measurements, disconnect the probe from
