VOLTCRAFT 1298223 Bedienungsanleitung Seite 22

For safety and approval reasons (CE), unauthorised conversion and/or modification of the device are not
permitted.
Consult an expert when in doubt as to the operation, the safety or the connection of the device.
Meters and accessories are not toys and have no place in the hands of children!
In commercial institutions, the accident prevention regulations of the Employer's Liability Insurance As-
sociations for Electrical Systems and Operating Materials are to be observed.
In schools, training centres, computer and self-help workshops, handling of meters must be supervised
by trained personnel in a responsible manner.
The voltage between the meter and the earth potential must not exceed 1,000 V DC/AC in CAT III or 600
V DC/AC in CAT IV.
Be especially careful when dealing with voltages higher than 33 V alternate (AC) or >70 V direct voltage
(DC)! Even at these voltages it is possible to receive a potentially fatal electric shock if you touch electri-
cal conductors.
Check the meter and its measuring lines for damage before each measurement. Never carry out any
measurements if the protecting insulation is defective (torn, ripped off etc.). The firmly connected
measuring cables and the flex current sensor have a wear indicator. When they are damaged, a second
insulation layer in a different colour becomes visible. Damaged measuring lines cannot be replaced. The
measuring unit must no longer be used and must be replaced.
To avoid electric shock, do not to touch the connections/measuring points directly or indirectly during
measurements. Never reach beyond the indicated grip area (5) during measurements.
No voltage must be applied to connected measuring lines (8). They are pure measuring outputs.
Do not use the adapter just before, during or just after a thunderstorm (lightning!) / high-energy overvolt-
age!). Make sure that your hands, shoes, clothing, the floor, circuits and circuit components are dry.
Never operate the product in direct proximity of:
- strong magnetic or electromagnetic fields
- Transmitter aerials or HF generators.
This could affect the measurement.
If you have reason to assume that safe operation is no longer possible, disconnect the device imme-
diately and secure it against inadvertent operation. It can be assumed that safe operation is no longer
possible if:
- the device shows visible damage
- the device no longer functions
- the device was stored under unfavourable conditions over an extended period of time or
- following considerable stress during transportation.
