weather conditions are appropriate and / or that suitable protection
measures are taken.
• 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 isolated from all current sources 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.
• 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.
• When connecting to a voltage, always connect the black measuring
lead rst before the red lead. Follow the reverse procedure when
disconnecting.
• If possible, do not work alone. Carry out measurements in
the vicinity of hazardous electrical installations only under the
guidance of a qualied electrician.
• The measuring tools and accessories are not toys.
Keep out of reach of children.
