Low Pass Filter; Voltage Measurement Up To 500 Mv; Temperature Measurement - Sonel CMM-60 Manual De Uso

To set other reference value in dBm mode:

in the measurement menu, select REF,

use arrows ▲▼ to c=select desired reference value: 4, 8, 16, 25, 32, 50, 75, 600 or 1000 Ω,

select OK.

6.1.3 Low pass filter

The meter is equipped with a low pass filter of alternating voltage with the threshold frequency of 1
kHz. This function blocks any voltage with a frequency exceeding 1 kHz. Voltages with a frequency
below the threshold are taken into account with reduced accuracy. The filter is useful in measuring the
signals of multiple sinusoidal sub-signals.
In voltage measurement mode for range of 1000 V:

select MENU,

use arrows and F1 F2 F3 F4 buttons to select
6.2

Voltage measurement up to 500 mV

To perform voltage measurement:

set the rotary switch at

select MENU and use arrows and F1 F2 F3 F4 buttons to set the measurement of:
 direct current voltage mVDC,
 alternating current voltage mVAC (default setting),

connect black test lead to COM terminal and red test lead to VΩ

contact the tips of test probes to the points of measurement; red probe should be applied to the
point of higher potential,

read the measurement result on the display,

after completing the measurements, remove test leads from the terminals of the meter.
6.3

Temperature Measurement

To perform the measurement:

set the rotary switch at

select MENU,

use arrows and F1 F2 F3 F4 buttons to set the temperature measurement Temp and unit – Cel-
sius C or Fahrenheit F,

place the adapter of the temperature probe in COM terminal (black leg) and VΩ
Hz% Temp (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 the meter.
