Do not use the device if the measuring wires appear to be defective. In case of damage replace them immediately. • Never ground yourself when measuring electricity. Do not touch any metal pipes, objects or parts that might be grounded. To ensure insulation from the ground, use insulating dry clothes, rubber-sole shoes or floor mats or other insulating materials. • Always disconnect the power source from the circuit before modifying it (soldering parts, etc.). Even weak currents might be dangerous. • Be careful when measuring above 60V DC or 30V AC! These voltages may cause electric shock! • When using the measuring prope, make sure that your fingers do not touch its metal parts and are always behind the finger protector. • To protect yourself and the device never exceed the maximal inward values. Exceeding these values may damage the device and the user may experience an electric shock while measuring. Safety symbols Symbols used in the manual and on the device ! WARNING: Check the referring pages of the manual. Improper usage may lead to damage to the device. Dangerous voltage.
