PeakTech 3280 Resistance Decade Box

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.
