• In overvoltage category III (CAT III - 1000 V), the voltage between the test device and earth must not
exceed 1000 V.
• In overvoltage category IV (CAT IV - 600 V), the voltage between the test device and earth must not
exceed 600 V.
• Use the device together with the measuring equipment only in the correct overvoltage category
(without protective cover CAT II - 1000 V; with protective cover CAT III - 1000 V and CAT IV - 600 V)
• The lowest overvoltage category (CAT), rated voltage and rated current apply when using the device
together with the measuring equipment.
• 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 connec-
ting 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 installations 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.
• 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.
• Only the original measuring leads may be used. Their voltage, category and ampere rated powers
must match those of the measuring device.
Additional information on use
Observe the technical safety regulations for working on electrical systems, especially: 1. Safely isolating
from power supply, 2. Securing to prevent system being switched on again, 3. Checking zero potential,
two-pole, 4. Earthing and short-circuiting, 5. Securing and covering adjacent live components.
