• 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 24 V/AC rms / 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.
• In overvoltage category III (CAT III), the voltage between the test
device and earth must not exceed 300 V.
• Before taking any measurements, make sure that both the area to
be tested (e.g. a line), the test device and the accessories used
(e.g. connection cable) are in proper working order. 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).
• The device must no longer be used if one or more of its functions
fail or the battery charge is weak.
• The device must be disconnected from all power sources and
measuring circuits before opening the cover to change the
battery(ies) or fuse(s). Do not switch on the device with the
cover open.
• Observe the safety precautions of local and national authorities
relating to the correct use of the device and any prescribed safety
equipment (e.g. electrician's safety gloves).
• If you have to take hold of the measuring spikes, do so by the
grip sections only. Do not touch the measuring contacts whilst
the measurement is being taken.
• Make sure that you always select the correct connections and
rotary switch position with the correct measuring range for the
measurement to be carried out.
• Do not work alone in the vicinity of hazardous electrical installa-
tions and only under the guidance of a qualified electrician.
• Disconnect the power supply to the electrical circuit before
measuring or checking the diodes, resistance or battery charge.
Make sure that all high-voltage capacitors are discharged.
To check, remove the measuring leads of the device from the test
piece before changing the mode.
• Check that all high-voltage capacitors are discharged.
• When connecting to a voltage, always connect the black
measuring lead first before the red lead. Follow the reverse
procedure when disconnecting.
