Safety guidelines
1. Prior to initiation of device’s usage it is recommended to get thoroughly
acquainted with operating manual and terms of safe use. This will allow
avoiding an electric shock, health damages or loss of life, as well as it may
prevent damages to the device.
2. Prior to commencing measurements it is recommended to check for dam -
ages on device’s casing or measuring cables. In case any cable or device
damages are detected device should not be used, as it may pose an electric
shock threat.
3. The device should not be used when insulation wrapping the probes and ca -
bles is damaged.
4. Only gauging cables delivered with the set may be used for measurements.
In case gauging cables are damaged they should be replaced with cables of
exact technical parameters.
5. The device can be used only for measurements compliant with the manual
and its technical specification. Otherwise, device’s safety provisions may
not be sufficient for safe usage.
6. During measurements all metal ends and gauging slots should not be
touched. Fingers should be kept above insulation sheaths.
7. It is not allowed to make measurements with wet hands or in places with
excessive air humidity.
8. It is not recommended to exceed upper limits of electric values given for
each gauging range. When the scale of measured electric value is not known
selection of the highest range is recommended for gauging.
9. It is not recommended to place any electronic elements into gauging slots
during voltage measurements with gauging probes.
10. Prior to measurement of resistance, circuit continuity and capacitor’s ca -
pacity the capacitances should be discharged and all power supply sources
disconnected.
11. Particular caution should be taken by measurements, which exceed DC 60 V
or AC 30 V rms.
12. Gauging probes should be removed from gauging slots prior to every change
of measured parameters.
13. The device should not be used, or kept, in high air humidity or temperature
conditions, in strong electromagnetic field or in an explosive or flammable
environment. Such conditions may influence gauging results and create an
electric shock hazard.
14. The device should not be used when the display indicates exhausted battery.
Low battery level may lead to faulty gauging indications.
15. Make sure that the device is switched off before batteries are replaced.
16. In case device is not used for a longer period of time the battery should be
removed in order to avoid spilling of electrolyte.
17. Device should be used and stored in a place inaccessible for children.
18. Device is designed to be used indoors, in room temperature.
19. Device should not be used directly after it is relocated from a room with
high air humidity, excessively low or high temperature conditions.

Safety category
CAT I
– gauging category CAT I defines safety requirements for measurements
in devices which are not connected directly to a low voltage network, such as
batteries, accumulators, flashlights.
CAT II – gauging category CAT II defines safety requirements for measure -
ments carried out in devices directly connected to a low voltage network, such
as home appliances, office equipment or workshop equipment.
CAT III
– gauging category CAT III defines safety requirements for measure -
ments carried out in the circuits of installations inside buildings.

Multimeter should not be used for measurements of devices de -
fined by CAT IV.
