Ill. Safety Notices
This instrument is to be used only by trained
and competent persons.
The instrument is designed and produced in strict
accordance with the safety requirements for Electronic
Measuring Apparatus and EN61010-1, EN61010-2-032,
EN61010-2-033, EN61010-031, EN61326-1 and
EN61326-2-2 standards, and complies with the safety
standard of double insulation, over-voltage CATII
1000V, CAT III 600V and pollution level 2. If you fail
to use the instrument according to relevant operation
instructions, the protection provided by the CombiVolt 5
instrument is likely to be weakened or undermined.
CAT II: Applicable to test and measuring circuits
connected directly to live voltage (socket outlets or
similar points) of the low voltage mains installation.
CAT Ill: Applicable to test and measuring circuits
connected to the distribution part of the building's
low-voltage MAINS installation.
1. Prior to using, please check the CombiVolt 5 and
integrated test lead & probe set for any damage or
abnormality. If any of the probes insulating layer or
lead are obviously damaged, the display screen fails
to display or you consider there is a fault with the
instrument, please do not use and contact Di-log for
further assistance.

2. It is strictly prohibited to use the CombiVolt 5
without the rear cover or battery cover, otherwise a
potential shock hazard may occur.
3. When carrying out any measurement, please
keep ngers behind the nger guards on both the
instrument and the test probes.
4. Before measurement, the instrument must be
switched to the correct functional position. It is prohibited
to switch the rotary dial to an alternative position
during measurement, so as to prevent the instrument
being damaged.
5. Do not apply in excess of 1000V DC/750V AC
between the CombiVolt test probes or between line
and ground so as to prevent electric shock and
instrument damage.
6. When the instrument is used to measure a DC
voltage (in excess of) >42V or AC TRMS voltage (in
excess of) >30V, it is necessary to operate the
instrument carefully as there may be danger of electric
shock.
7. Do not measure voltage or current higher than
the stated input limits. Before measuring resistance,
diode or continuity, it is essential to isolate all power
supplies in the circuit and discharge all capacitors,
otherwise, it may lead to incorrect measurement
results.

component to be measured, the instrument will
automatically select the correct range. The central
screen will display the current value of resistance;
Warning:
During the measurement of resistance, the power
must be isolated before connecting, and the residual
electric charge of all capacitors should be fully

6. Continuity Testing (CON)
(1) Set the rotary dial to “ “; Press “SELECT” button
on the measuring function range once to select
Continuity.
(2) Connect the red and black test probes to the
component or circuit to be tested. If the measured
resistance is below 10Ω, the audible alarm will sound
continuously; If the measured value is between 10Ω
and 100Ω the audible alarm may not sound. If the
measured value is greater than 100Ω, the audible
alarm will not sound.
Warning;
When measuring on-o condition, the circuit power
must be isolated. All the residual electric charge of
all electric capacitors must be fully discharged before
the components or conductors are connected with
this product.

7. Diode Measurement (DIO)
(1) Set the rotary dial to “ “; Press “SELECT”
button on the measuring function range twice to select
Diode.
(2) Connect the red and black test probes to the positive
and negative poles of the diode to be tested. The
positive conductivity voltage value will be displayed
in the centre of the screen; If the probes are connected
to the incorrect polarity, the screen shall display the
measurement sign “OL”;
Warning:
When measuring the diode, the circuit power must
be isolated and electric charge of all electric capacitors
must be fully discharged before the diode is connected
with the product. More accurate measurement will
be possible when the components are separated
from the circuit.

8. Measuring of Capacitance (CAP)
(1) Set the rotary dial to “ “; Press “SELECT” button on
the measuring function range three times to select
Capacitance.
(2) Connect the red and black test probes to the two
sides of the capacitor to be tested and the instrument
will select the correct range. The display screen will
display the current value of capacitance.
Warning:
During the measurement of capacitance, the power
must be isolated before connecting, and the residual
electric charge of all capacitors must be fully discharged.
More accurate measurement may be possible when
the elements are separated from the circuit. Before
measuring the capacitance, the “REL” key should be
pressed to clear the base number to eliminate the
eect of probe parasitic capacitance.
Note:
At the range 60nF, it is suggested to rstly press
the “REL” key to clear the short circuit base number
before measurement, to eliminate impact of probe
resistance.

9. Non-contact Voltage Indication (NCV)
(1) Set the rotary dial to “ NCV “;
(2) Connect the instrument to the conductor to be
checked. The top right end of the clamp head is
equipped with a sensor.
The screen will display “EF” if the induced voltage
is not detected. When the test distance is less than
10cm and the tested voltage is greater that 100Vrms
the instrument will emit an audible alarm the NCV
LED light will also start to icker. According to the
magnitude of voltage present, the display screen will
display four levels as “-”, “- -”, “- - -” or “- - - -”. The
greater the voltage, the higher the level displayed.
Warning:
This unit can only be used as a single pole voltage
detector when batteries are inserted. The single
pole test is intended only as a quick check, the circuit
must be checked again for the presence of voltage
using the AC voltage setting and 2 pole method.

10. Single Pole Voltage Detection (SPD)
(1) Set the rotary dial to “SPD“;
(2) Connect the red or black test probe to the conductor
to be checked making direct contact with either of
the probes. Detection of Single Pole Voltage can be
achieved with either the red or black test probe as
both are equipped to indicate if voltage is present in
excess of 100Vrms.
If an AC voltage above 100Vrms is present, the LED
is illuminated and the audible alarm will sound. The
screen will display “EF” if no voltage is detected.
When the contact voltage is greater than 100Vrms,
the meter will indicate with an audible alarm and the
NCV/SPD LED alarm light will also start to icker.
According to the magnitude of voltage present, the
central screen will display the four levels as “-”, “- -”,
“- - -” or “- - - -”. The greater the voltage, the higher
the level displayed.
Warning:
This unit can only be used as a single pole voltage
detector when batteries are inserted. The single
pole test is intended only as a quick check, the circuit
must be checked again for the presence of voltage
using the AC voltage setting and 2 pole method.
