Function/Application

Voltage and continuity tester for automatic measurement

of AC (alternating current) and DC (direct current) voltages.

The device can be used to perform a single-phase test and a

rotating Ö eld test while also indicating the phase direction. The

information is indicated by means of an LED display and an

acoustic signal.

Safety instructions

• The device must only be used in accordance with its intended

purpose and within the scope of the speciÖ cations.

• Before every measurement make sure that the area to be

checked (e.g. line) and the tester are in perfect operating

condition. Test the device by connecting it to known

voltage sources (e.g. a 230 V socket in the case of AC

testing or a car battery in the case of DC testing). Stop

using the device if one or a number of its functions fails.

• If you are working with voltages higher than 25 V AC/60 V

DC, exercise extreme caution. Touching the electrical conduc-

tors at such voltages poses a risk of life-threatening electric

shocks. Take particular care if the 50V warning LED is on.

• Do not use the device in environments in which there are

con-ductive particles or where the occurrence of moisture (in

the form of condensation, for example) can create transient

conductivity.

• If the device comes into contact with moisture or other

conductive residue, work must not be carried out under

voltage. At and above voltages of 25 V AC/60 V DC, the

presence of moisture creates the risk of life-threatening

electric shocks. Clean and dry the device before use. When

using the device outdoors, make sure that the weather

conditions are appropriate and/or that suitable protection

measures are taken.

• If you are taking measurements in the hazardous vicinity of

electrical installations, do not work alone and seek guidance

from an electrically skilled person before starting work.
