• When the indication"Voltage Present" appears on a part that is

expected to be disconnected from the installation, it is highly

recommended confirming by another means (e.g. use of an

adequate voltage detector, visual check of the disconnecting point of

the electric circuit, etc.) that there is no operating voltage on the

part to be tested and to conclude that the voltage indicated by the

voltage detector is an interference voltage.

• A voltage detector declaring two values of internal impedance has

passed a performance test of managing interference voltages and is

(within technical limits) able to distinguish operating voltage from

interference voltage and has the means to directly or indirectly

indicate which type of voltage is present.

2. Appropriate Usage

• The instrument may only be used under those conditions and for

those purposes for which it was manufactured. For this reason, the

safety references, the technical data including environmental

conditions and the usage in dry environments must be followed.

• When modifying or changing the instrument, the operational safety

is no longer guaranteed.

• The instrument may only be opened by an authorized service

technician.

• The voltage detectors are designed to be used by skilled persons

and in accordance with safe work practice.

• Before using a voltage detector with audible indicator at locations

with a high back ground noise level, it has to be determined whether

the audible signal is perceptible.
