Intended use

- Measuring and displaying electric parameters in the range of excess voltage category
III (up to max. 600 V against ground potential, pursuant to EN 61010-1) and all lower
categories.
- Measuring direct and alternating voltage up to a maximum of 600 V
- Measuring of resistance up to 20 MΩ
- Acoustic continuity check
- Diode test
- Non-contact 230 V/AC voltage test
- Electric current measurement (10 A, mA μA, VC155 only)
- K-type temperature measurement (VC155 only)
The two measuring inputs are secured against overload. The voltage in the measuring circuit
may not exceed 600 V. The measuring ranges are equipped with ceramic high-performance
fuses.
The device may only be operated with a 9 V block battery.
The measuring instrument must not be operated when it is open, i.e. with an open battery
compartment or when the battery compartment cover is missing. Measuring in damp rooms or
under unfavourable ambient conditions is not admissible.
For safety reasons, when measuring only use measuring cables or accessories which are
adjusted to the specifications of the multimeter.
Unfavourable ambient conditions are:
• Wetness or high air humidity,
• Dust and flammable gases, vapours or solvent,
• Thunderstorms or similar conditions such as strong electrostatic fields etc.
For safety and approval purposes, you must not rebuild and/or modify this product. If you use
the product for purposes other than those described above, the product may be damaged.
In addition, improper use can cause hazards such as short circuiting, fire, electric shock etc.
Read the instructions carefully and keep them. Make this product available to third parties only
together with its operating instructions.

Symbol explanation

An exclamation mark in a triangle indicates important instructions in the operating
manual which absolutely have to be observed.
The triangle containing a lightning symbol warns of danger of an electric shock or
of the impairment of the electrical safety of the device.
This product has been CE-tested and meets the necessary European guidelines.
Class 2 insulation (double or reinforced insulation)
Overvoltage category II for measurements on electric and electronic devices
CAT II connected to the mains supply with a power plug. This category also covers all
smaller categories (e.g. CAT I for measuring signal and control voltages).
Overvoltage category III for measuring in building installation (e.g. outlets or
CAT III subdistribution). This category also covers all smaller categories (e.g. CAT II for
measuring electronic devices).
Ground potential
The symbol can be found when you are to be given tips and information on
operation.
Safety instructions
Read the operating instructions carefully and especially observe the safety
information. If you do not follow the safety instructions and information
on proper handling in the manual, we assume no liability for any resulting
personal injury or damage to property. Such cases will invalidate the
warranty/guarantee.
a) General information
• The device is not a toy. Keep it out of the reach of children and pets.
• Do not leave packaging material lying around carelessly. This may become
dangerous playing material for children.
• Protect the product from extreme temperatures, direct sunlight, strong jolts, high
humidity, moisture, flammable gases, vapours and solvents.
• Do not place the product under any mechanical stress.
• If it is no longer possible to operate the product safely, take it out of operation and
protect it from any accidental use. Safe operation can no longer be guaranteed
if the product:
- is visibly damaged,
- is no longer working properly,
- has been stored for extended periods in poor ambient conditions or
- has been subjected to any serious transport-related stresses.
• Please handle the product carefully. Jolts, impacts or a fall even from a low height
can damage the product.
• Also observe the safety and operating instructions of any other devices which are
connected to the product.
• Consult an expert when in doubt about operation, safety or connection of the
device.
• Maintenance, modifications and repairs are to be performed exclusively by an
expert or at a qualified shop.
• If you have questions which remain unanswered by these operating instructions,
contact our technical support service or other technical personnel.
b) Batteries / Rechargeable batteries
• Correct polarity must be observed while inserting the batteries.
• Batteries should be removed from the device if it is not used for a long period of
time to avoid damage through leaking. Leaking or damaged batteries might cause
acid burns when in contact with skin, therefore use suitable protective gloves to
handle corrupted batteries.
• Batteries must be kept out of reach of children. Do not leave the battery lying
around, as there is risk, that children or pets swallow it.
• Batteries must not be dismantled, short-circuited or thrown into fire. Never
recharge non-rechargeable batteries. There is a risk of explosion!
