Safety Instructions

All instructions must be read and observed. The safeguards integrated into the voltage tester may be compromised if the voltage tester is not used in accordance with these instructions. STORE THESE INSTRUCTIONS IN A SAFE PLACE.

• Do not perform any measurements on electric circuits with voltages exceeding 1000 V.

• Do not use the voltage tester to determine the absence of voltages.

• Do not use the voltage tester if it looks damaged or it is not working properly. Test the test tips before using on cracks or breakages.

• Take extra care when working with voltages over 30 V AC or 60 V DC! Even at these voltages, contact with live cables can cause life-threatening electric shocks.

• Even if there is no visual or acoustic signal, there may still be a voltage. Insulation, wire size, cable shielding or the removal of the voltage source can influence the test.

• Make sure that you are properly earthed when taking measurements. If you are not properly earthed (e.g. by wearing insulating footwear or by standing on a ladder), the voltage tester is unable to detect any voltages.

• The voltage tester must only be used by qualified personnel in accordance with safe working practices.

• Only have the voltage tester repaired by qualified personnel using only original spare parts. This will ensure that the safety of the voltage tester is maintained.

• Do not use the voltage tester in explosive atmospheres which contain flammable liquids, gases or dust. Sparks may be produced inside the voltage tester, which can ignite dust or fumes.

• The voltage tester cannot detect a voltage in DC circuits or in shielded cables.

• Do not subject the voltage tester to extreme temperatures or variations in temperature. As an example, do not leave it in vehicles for longer periods. In case of large variations in temperature, allow the voltage tester to adjust to the ambient temperature before putting it into operation. The precision of the voltage tester may be compromised if exposed to extreme temperatures or fluctuations in temperature.
