Safety Precautions
This product complies with the requirements of the following directives of the European Union for CE conformity: 2014/35/EU (low voltage), 2011/65/EU (RoHS). Pollution degree 2.
To ensure safe operation of the equipment and eliminate the danger of serious injury due to short-circuits (arcing), the following safety precautions must be observed.
Damages resulting from failure to observe these safety precautions are exempt from any legal claims whatever.
- Do not use this instrument for high-energy industrial installation measurement.
- Do not exceed the maximum permissible input ratings (danger of serious injury and/or destruction of the equipment).
- Check test leads and probes for faulty insulation or bare wires before connection to the equipment.
- To avoid electric shock, do not operate this product in wet or damp conditions. Conduct measuring works only in dry clothing and rubber shoes, i. e. on isolating mats.
- Comply with the warning labels and other info on the equipment
- Do not subject the equipment to direct sunlight or extreme temperatures, humidity or dampness.
- Do not subject the equipment to shocks or strong vibrations.
- Do not operate the equipment near strong magnetic fields (motors, transformers etc.).
- Keep hot soldering irons or guns away from the equipment.
- Allow the equipment to stabilize at room temperature before taking up measurement (important for exact measurements).
- Periodically wipe the cabinet with a damp cloth and mid detergent. Do not use abrasives or solvents.
- The instrument is suitable for indoor use only
- Do not store the meter in a place of explosive, inflammable substances.
- Do not modify the equipment in any way
- Do not place the equipment face-down on any table or work bench to prevent damaging the controls at the front.
- Opening the equipment and service – and repair work must only be performed by qualified service personnel
- Measuring instruments don’t belong to children hands.
