Safety Notes - VOLTCRAFT VC-450 E Bedienungsanleitung

6. Safety notes

Read the operating instructions attentively and particularly observe the safety notes. If the safety
notes and the information in these operating instructions regarding proper handling are not ob-
served, we assume no liability for any resulting injury/property damage. In such cases, the war-
ranty/guarantee will also lapse.
• For safety and approval reasons, unauthorised conversion and/or modification of the device are not
permitted.
• Consult an expert when in doubt as to the operation, 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-
sociation 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.
• Ensure before every measurement that the meter is set to the proper measuring function.
• When using the measuring prods without cover caps, measurements between the meter and the earth
potential must not be performed above the measuring category CAT II.
• When measuring in the measuring category CAT III and CAT IV, measuring prods with cover caps (max.
4 mm free contact length) must be used to avoid accidental short circuits during measurement. They are
enclosed.
• The measuring prods have to be removed from the measured object every time the measuring function
is changed.
• The voltage between the connection points of the meter and the earth potential must not exceed
1000 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 alternating (AC) or 70 V direct volt-
age (DC)! Even at these voltages it is possible to receive a potentially fatal electric shock if you touch
electrical conductors.
• To avoid electric shock, make sure not to touch the connections/measuring points to be measured di-
rectly or indirectly during measurement. During measuring, do not grip beyond the tangible grip range
markings present on the measuring prods.
• 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 enclosed measuring
cables have a wear indicator. When they are damaged, a second insulation layer in a different colour
becomes visible. The measuring accessories must no longer be used and must be replaced.
• Do not use the multimeter just before, during or just after a thunderstorm (lightning! / high-energy over-
voltage!). Make sure that your hands, shoes, clothing, the floor, circuits and circuit components are dry.
