Safety

Read this manual carefully before starting or using the device. Always store the manual in the immediate vicinity of the device or its site of use.

Warning
Read all safety warnings and all instructions.
Failure to follow the warnings and instructions may result in electric shock, fire and / or serious injury.
Save all warnings and instructions for future reference.

• Do not use the device in potentially explosive rooms or areas and do not install it there.

• Do not use the device in aggressive atmosphere.

• Protect the device from permanent direct sunlight.

• Do not remove any safety signs, stickers or labels from the device. Keep all safety signs, stickers and labels in legible condition.

• Do not open the device.

•  Never charge batteries that cannot be recharged.

• Different types of batteries and new and used batteries must not be used together.

• Insert the batteries into the battery compartment according to the correct polarity.

• Remove discharged batteries from the device. Batteries contain materials hazardous to the environment. Dispose of the batteries according to the national regulations.

• Remove the batteries from the device if you will not be using the device for a longer period of time.

• Never short-circuit the supply terminal in the battery compartment!

• Do not swallow batteries! If a battery is swallowed, it can cause severe internal burns within 2 hours! These burns can lead to death!

• If you think batteries might have been swallowed or otherwise entered the body, seek medical attention immediately!

• Keep new and used batteries and an open battery compartment away from children.

• The device is only designed to display the voltage range and is not suitable for measuring purposes.

• Immediately before and after each use, test the voltage detector for proper functioning. The voltage detector must not be used if one or several indications on the voltage detector fail or if the functionality of the device cannot be clearly recognized.

• The voltage detector may only be used within the specified rated voltage range and in electrical installations of up to 400 V AC and 690 V DC.

•  The voltage detector may only be used in circuits of overvoltage category CAT III with max. 600 V conductor to earth.

• When using the voltage detector, do not touch the test probes, and only hold the device by the insulated handles. The voltage detector must not be used when the battery
  compartment is open.

• At locations with load background noises, check whether the acoustic signals of the device can be perceived before using the device.

• For technical reasons, the device cannot display DC voltages within the range of approx. 0 V to 8 V.

• Observe the maximum permissible duty cycle of 30 seconds for voltage detection. The device must never be applied to voltages for more than 30 seconds.

• For technical reasons, the device must not be operated for  10 minutes after each voltage detection. The device mayonly be used again for the next voltage detection after  the rest period of 10 minutes has elapsed.

• After each use, screw the supplied test probe protectors onto the two test probes to prevent injuries.

• Depending on the internal impedance of the voltage detector, the device may either indicate “operating voltage present” or “operating voltage not present” if an interference voltage is present.

• A voltage detector with a relatively low internal impedance will not indicate all interference voltages with an initial value above ELV, compared to the reference value of 100 kΩ. Upon contact with the system parts to be checked, the voltage detector may temporarily reduce the interference voltages by discharging to a level below ELV; however, after the voltage detector has been removed, the interference voltage will assume its original value again.

• If the “voltage present” indication does not appear, it is highly recommended that you insert the earthing device before starting work.

• A voltage detector with a relatively high internal impedance will not clearly indicate “operating voltage not present” if an interference voltage is present, compared to the reference value of 100 kΩ.

• If the “voltage present” indication appears for a part that is considered to be disconnected from the system, it is highly recommended that you take additional measures  (e.g. using an additional suitable voltage detector, visual inspection of the disconnection point in the electric network, etc.) to check the “operating voltage not present” state of the system part to be checked, and to make sure that the voltage indicated by the voltage detector is an interference voltage.

• A voltage detector indicating two internal impedance values has passed the design test for handling interference voltages and – within the technical limits – is able to differentiate between operating voltage and interference voltage, and to directly or indirectly indicate the existing type of voltage.

• Observe the storage and operating conditions (see Technical data).
