VC-13A ANALOG MULTIMETER
ITEM NO. 1386327
INTENDED USE
• Measuring and displaying electrical values in the range of measurement category CAT III up to max. 300 V
against earth potential, pursuant to EN 61010-1
• Alternating and direct voltage measurements up to max. 300 V
• Measurement of direct current up to 250 mA
• Attenuation measurements from -20 dBm to +22 dBm
• Measurement of resistance up to 2 MOhm
• Battery test for 1.5 V and 9 V batteries
The multimeter may be operated only with a Mignon battery (AA, UM3, LR6 or equivalent).
The measuring instrument must not be used when it is open, i.e. with an open battery compartment or
when the battery compartment cover is missing. Do not make measurements in potentially explosive areas
(Ex) or damp rooms or under unfavourable ambient conditions. Adverse ambient conditions include: Damp
or high humidity, dust and flammable gases, fumes or solvents, and thunderstorms or thunderstorm condi-
tions like strong electrostatic fields, etc.
For safety reasons, when measuring only use measuring cables or accessories that are suitable for the
specifications of the multimeter.
Measurements in circuits >33 V/AC and >70 V/DC may be carried out only by specialists and trained
persons who are familiar with the pertinent regulations and the resulting dangers.
Any use other than that described above can lead to damage to the product and may involve additional
risks such as short circuits, fire, electric shock etc. No part of the product may be modified or converted!
The safety instructions are to be observed without fail!

DESCRIPTION OF SYMBOLS
An exclamation mark in a triangle indicates important information
contained in these operating instructions that must be observed by all means.
The lightning symbol in a triangle warns of electric shock danger or the impairment of the
electrical safety of the appliance.
The "arrow" symbol is used where special tips and notes on operation are provided.
This product has been CE tested and complies with the required European guidelines.
Class 2 insulation (double or reinforced insulation).
CAT III Measurement Category III for measuring circuits of installations in buildings (e.g. electric
sockets or sub-distributions). This category also includes all lower categories (e.g. CAT II for
measuring on electrical devices and CAT I for measuring signal and control voltages). The
measuring operation in CAT III is permitted only with probe tips with a maximum free contact
length of 4 mm or with cover caps over the probe tips.

SAFETY INSTRUCTIONS
Please read all the instructions before using this device, they include important informa-
tion on its correct operation.
Damages caused by failure to follow these operating instructions will void the warranty/
guarantee! We do not assume any liability for any resulting damage!
We do not assume any liability for personal injuries and material damages caused by the
improper use or non-compliance with the safety instructions! In such cases, the warranty
will be null and void.
• This device has left our factory premises in a safe and perfect condition.
• We kindly request the user to observe the safety instructions and warnings contained in the
enclosed operating instructions so this condition is maintained and to ensure safe operation.
• The unauthorised conversion and/or modification of the unit is not permitted for safety and
approval reasons (CE).
• Consult a professional if you are unsure how to operate the equipment or how to connect it
safely.
• Meters and their accessories are not toys and should be kept out of the reach of children!
VERSION 01/16 • In commercial institutions, the accident prevention regulations of the Employer's Liability
Insurance Association for Electrical Systems and Operating Facilities are to be observed.
• In schools, training centres, hobby and self-help workshops, use of the measuring device
must be supervised by trained personnel in a responsible manner.
• Before measuring voltages, always make sure that the measuring instrument is not set to a
measuring range for currents.
• The voltage between any socket of the measuring instrument and earth may not exceed 300
V (DC/AC) in Measurement Category III.
• Be especially cautious when dealing with voltages exceeding >33 V (AC) or >70 V (DC)! Even
at these voltages, there is a danger of fatal electric shock if you touch electric conductors.
• To eliminate the risks of electric shock, do not directly or indirectly touch the connections/
measuring points during measurements. During measuring, do not grip beyond the tactile grip
range markings on the test probes.
• Do not use the multimeter just before, during or just after an electrical storm (electrical shock!
/ high-power surges!). Make sure that your hands, shoes, clothing, the floor, the measuring
device and/or measuring lines, circuits and circuit components are always dry.
• Do not use the tester in rooms or under adverse ambient conditions in which flammable
gases, vapours or explosive dust may be or are present.
• Avoid operation near strong magnetic or electromagnetic fields, transmitter aerials or HF
generators. These can distort the measurement.
• For safety reasons, use only measuring cables or accessories which are adjusted to the
specifications of the multimeter when measuring. Only use double, or strengthened, insulated
measuring accessories.
• If you have reason to assume that safe operation is no longer possible, disconnect the device
immediately and secure it against inadvertent operation. Safe operation can no longer be
assumed if:
- the device is visibly damaged,
- the device does not function any more and
- the device was stored under unfavourable conditions for a long period of time or
- it has been subjected to considerable stress during transportation.
• Do not switch the measuring instrument on immediately after it has been taken from a cold
to a warm environment. The condensation that forms might destroy your device. Allow the
device to reach room temperature before switching it on.
• Do not leave packaging material carelessly lying around, as it could become a dangerous
plaything for children.
• Also pay attention to the safety instructions in each chapter of these instructions.
DESIGNATION OF INDIVIDUAL PARTS
PRODUCT DESCRIPTION
• The analogue multimeter (hereinafter referred to as multimeter) is equipped with a shock-attenuating
pointer instrument.
• The multimeter can be used in any operating position.
• The mA-current range is protected against overload with a micro fuse.
• The individual measuring functions and ranges are selected with a rotary switch.
• The multimeter can be used for up to CAT III max. 300 V for hobby or professional applications.
• On delivery, the measuring leads may be covered by protective sleeves. Before use, pull the sleeves off
the safety plugs.
• After use, put them back for transport protection.
• The scale pointer can be calibrated with the calibration screw. Perform this before each measurement to
prevent inaccurate measurements.
