Explanation of symbols
Protection class II insulation (double or reinforced insulation)
CAT I
Measurement category I for measurements on signal and control voltages without powerful
discharges.
CAT II Measurement category II for measurements on electric devices connected to the mains
supply by a power plug. This category also covers all smaller categories (e.g. CAT I for
measuring signal and control voltages).
CAT III Overvoltage category III for measuring in building installation (e.g. outlets or subdistribution).
This category also covers all lower categories (e.g. CAT II for measuring electronic devices).
The symbol with the lightning in the triangle is used if there is a risk to your health, e.g. due
to an electric shock.
The symbol with the exclamation mark in the triangle is used to indicate important informati-
on in these operating instructions. Always read this information carefully.

• Also observe the safety and operating instructions of any other devices which are connected
• Pouch
• Operating instructions
to the product.
• The product is only allowed to be connected and operated at a safety socket.
• The mains outlet must be located near to the device and be easily accessible.
• Never pull the mains plug from the socket by pulling at the cable. Always pull it from the
mains socket using the intended grips.
• Unplug the mains plug from the mains socket if you do not use the device for an extended
period of time.
• Disconnect the mains plug from the mains socket in thunderstorms for reasons of safety.
• Make sure that the mains cable is not squeezed, bent, damaged by sharp edges or put
under mechanical stress. Avoid excessive thermal stress on the mains cable from extreme
heat or cold. Do not modify the mains cable. Otherwise the mains cable may be damaged. A
damaged mains cable can cause a deadly electric shock.
• Do not touch the mains cable if it is damaged. First, power down the respective mains socket
(e.g. via the respective circuit breaker) and then carefully pull the mains plug from the mains
socket. Never use the product if the mains cable is damaged.
• A damaged mains cable may only be replaced by the manufacturer, a workshop commis-
sioned by the manufacturer or a similarly qualified person, so as to prevent any danger.
• Never plug in or unplug the mains plug when your hands are wet.
• This product has been constructed in accordance with the safety provisions for electronic
measuring and test devices and left the factory in a proper safety condition. To maintain
this condition, the user has to observe the safety guidelines in these operating instructions.
• For all work the respectively valid accident prevention regulations of the professional associ-
ations for electrical systems and equipment have to be observed.
• To prevent the risk of electric shock, it is imperative to observe all prevailing safety and
DIN VDE regulations concerning inadmissible high contact voltage, if you are working with
voltages over 120 V (60 V) DC or 50 V (25 V) AC eff.
• Measurements made dangerously close to electrical systems are only to be performed under
the instructions of a responsible electrician and not alone.
• This product is only allowed to be used at the nominal voltages stated in the technical data.
• If the product is exposed to an extremely high electromagnetic field, its function may be
