• When connecting to a voltage, always connect the black measu-
ring lead first before the red lead. Follow the reverse procedure
when disconnecting.
• Isolate the device from all current sources before opening the
battery compartment cover. Do not switch on the device with the
cover open.
• If possible, do not work alone. Carry out measurements in the
vicinity of hazardous electrical installations only under the guidance
of a qualified electrician.
• 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.
• If you are working with voltages higher than 25 V AC/50 V DC,
exercise extreme caution. Touching the electrical conductors at
such voltages poses a risk of life-threatening electric shocks.
• 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/50 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.
• 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).
Stop using the device if one or a number of its functions fails.
• Do not expose the device to mechanical stress, extreme temperatu-
res or significant vibration.
• The device must only be used in accordance with its intended
purpose and within the scope of the specifications. Modifications
or changes to the device are not permitted, this will otherwise
invalidate the approval and safety specifications.
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).
