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 w hile 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 w ith its intended
purpose and w ithin 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 know n
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 w orking w ith 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 w arning LED is on.
• Do not use the device in environments in w hich there are
con-ductive particles or w here the occurrence of moisture (in
the form of condensation, for example) can create transient
conductivity.
• If the device comes into contact w ith moisture or other
conductive residue, w ork 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 w eather
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 w ork alone and seek guidance
from an electrically skilled person before starting w ork.
• Isolate the device from all current sources before opening the
battery compartment cover.
