2 Safety
2.1 General rules
In order to provide conditions for correct operation and the correctness of the obtained results, the
following recommendations must be observed:
before using the meter read carefully this manual,
the meter should be operated only by qualified persons that have passed health and safety training,
be very careful when measuring voltages exceeding (as per IEC 61010-1:2010/AMD1:2016):
60 V DC,
30 V AC RMS,
42,4 V AC of peak value,
as they generate a potential risk of electric shock,
do not exceed the maximum limits of the input signal,
during the voltage measurements do not switch the device in the current or resistance measuring
mode and vice versa,
when changing ranges (changing the position of the rotary switch) always disconnect the test leads
from the tested circuit,
measuring probes should be kept in the space provided, restricted by a special barrier to avoid acci-
dental contact with exposed metal parts,
if during the measurement OL symbol is displayed, it indicates that the measured value exceeds the
measurement range. Switch to a higher range.

3 Preparing the meter for operation
After purchasing the meter, check whether the content of the package is complete.
Before performing the measurement:
make sure that the battery level is sufficient for measurements,
make sure that the device has fuse installed and efficient,
check whether the meter casing and insulation of the test leads are not damaged,
to ensure consistent measurement results it is recommended to connect black lead to COM terminal
and red lead to other terminals,
WARNING:
Connecting wrong or damaged leads may cause electric shock.
WARNING:
Do not perform the measurements if the potential of the COM terminal to earth exceeds 1000 V.
WARNING:
The meter must not be connected to the voltage source when it is set to current or resistance
measurement or to diode test. Failure to observe this precaution may damage the meter!
When using the meter, be sure to:
discharge capacitors in the tested power sources,
disconnect the power supply from the tested object when measuring the resistance and diode tests,
turn off the meter and disconnect test leads before removing the back cover to replace the battery or
fuses.
WARNING:
Do not use the meter if the cover of battery and fuse compartment is removed.
Note:
It is possible that in certain low ranges of AC or DC voltage, when the meter is not connected
to the leads, the screen will show random and variable readings. This is a normal phenomenon,
which results from the input sensitivity with high input resistance. When connected to a circuit,
the read-out will stabilize and the meter will provide the correct value.

6 Measurements
The content of this chapter should be thoroughly read and understood since it describes methods
of measurements and basic principles of interpreting measurement results.
6.1 Voltage measurement up to 1000 V
WARNING:
Electric shock hazard. The ends of measuring probes, due to their length, may not reach the
live parts inside some network connections of low-voltage electrical equipment, because the
contacts are arranged inside the sockets. In such a case, the read-out will be 0 V with the sim-
ultaneous presence of voltage in the socket.
Before acknowledging the absence of voltage in the socket make sure that the ends of the of
the probe touch the metal contacts inside the socket.
NOTE
Do not measure the voltage when an electric motor located within the circuit is being switched
on or off. Resulting voltage spikes may damage the meter.
6.1.1 Performing the measurement
To perform voltage measurement:
set the rotary switch at V,
select MENU and use arrows and F1 F2 F3 F4 buttons to set the measurement of:
direct current voltage VDC,
alternating current voltage VAC (default setting),
connect black test lead to COM terminal and red test lead to VΩCAP Hz% Temp terminal,
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.
6.1.2 Voltage measurement in dB
For range 1000 V, the meter may display the result of measurement as the attenuation expressed in
decibels (dB), in the form of:
the reference to 1 V (dBV mode)
the reference to 1 mW (dBm mode),
the reference to a value set by the user.
For this purpose:
set the rotary switch at V,
select MENU and use arrows and F1 F2 F3 F4 buttons to set dBV or dBm.
connect black test lead to COM terminal and red test lead to VΩCAP Hz% Temp terminal,
contact the tips of test probes to the points of measurement; red probe should be applied to the
point of higher potential,
read the result of the measurement –the main result is expressed in V and its equivalent is ex-
pressed in dB.
9

CMM-60 –USER MANUAL
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.

7.3 MAX/MIN mode
For each measurement function, this mode displays three values in the form of True RMS:
Minimum recorded value of the measurement,
Average of all recorded measurements,
Maximum recorded value of the measurement.
Prerequisite: the duration of the record must exceed 100 ms.
If the measured signal drops below the current minimum value or exceeds maximum value, the
readings will be updated to the value of this signal. The meter records also date, time and the period
after which it recorded these values.
Using the function:
Use the rotary switch to select the desired measuring function
Press MAX/MIN button
use F1 F2 F3 F4 buttons to select one of the options:
Restart - resetting the readings and restarting the recording,
STOP - stopping the recording and presentation of the most recent readings,
SAVE - saving records to the meter's memory. Active after selecting STOP. Detailed de-
scription in section 7.6.2.
CLOSE - closing the function without saving results.
Note:
When the meter switches off automatically and then it is restarted with ESC button, data on the
screen will be lost.
7.4 HOLD function

An additional mode of the function is AutoHold. It monitors the input signal and updates the "fro-
zen" read-out, when the meter detects a new stable value of the signal (such that variations for at
least 1 s. do not exceed the setpoint –sec. 7.7.3).
In addition, the meter detects open measurement circuit. This allows user to plug the meter into a
different circuit, without losing the current reading from the screen.
Using the function:
to activate, use F1 F2 F3 F4 buttons and select AUTOHOLD,
to save the result use F1 F2 F3 F4 buttons to select SAVE,
to turn off, select CLOSE or CANCEL.
