provided by the equipment may be impaired!
This equipment can be used to carry out measurements in the CAT.III1600V
environment.
When using this clamp meter, the user should comply with all the safety measures
regarding:
-Protection against the electric current hazards.
-Protection of the clamp A-meter against incorrect use.
-Protection against electric shock hazard.
For operator security, only the test probes supplied with the instrument shall be used.
Do not use the clamp-meter and its accessories ifany damage is detected!
During use
Before carrying out any measurements, the instrument shall be warmed up for at least
30 seconds.
If the clamp-meter is used near any high level noise source, the screen might become
unstable or there may appear errors in display.
The maximum limits of the input value shown in the technical specification tables shall
not be exceeded in order to avoid damage to the equipment.
The rotary switch shall be in the correct position before starting a new measurement.
Exerciseextremecautionwhenworkingnearbareconductorsorbus-bars.Anyaccidental
contact with the bare conductor may cause an electric shock.
Work carefully with voltages higher than 60 VDC. or 30 VACrms to avoid a risk of electric
shock.
The test probe(s) shall be disconnected from the circuit that is being tested before
changing the function.
During measurement fingers shall always be kept behind the protection guard (check
point 2 of this manual)
The battery shall be changed when the symbol is shown in order to avoid incorrect
measurement readings.
(1): Measurement protective category III covers measurements performed in the building
installation. Examples are measurements on distribution boards, circuit-breakers, wiring,
including cables, bus-bars, junction boxes, switches, socket-outlets in the fixed installation,
equipment for industrial use, and some other equipment, for example, stationary motors with
permanent connection to thefixed installation.
