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 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 speci 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.
• Isolate the device from all current sources before opening the
battery compartment cover.
