3. INTENDED USE
- Measuring and displaying electric parameters in the range of measurement category CAT III up to 600 V against
earth potential, pursuant to EN 61010-1 and all lower measuring categories. The meter must not be used in the
measuring category CAT IV.
- Measurement of direct and alternating voltage up to 600 V
- Measurement of direct and alternating current up to 10 A
- Measurement of resistances up to 20 MΩ
- Acoustic continuity test (<50 Ω)
- Diode test
- Contact-free recognition of alternating voltage 220 V/AC, 50 - 60 Hz.
The measurement functions are selected using the dial switch. The measuring range is selected automatically for all
measuring functions (except for diode test, continuity test and NCV). Manual measuring range selection is possible
in the two V-measuring ranges (marked “RANGE”).
The VC165 shows actual effective measured values (True RMS) in the AC voltage and current measuring ranges.
Polarity is automatically indicated with the minus prex (-) if the measured values are negative.
Use of personal protection equipment is recommended for measurements in CAT III environments. The meter must
not be used in the measuring category CAT IV.
An integrated LED lamp can be used as a ashlight for dark areas.
The multimeter is operated with a conventional 9 V block battery (type 6F22, NEDA1604 or same build). The device
must only be operated with the specied battery type. Rechargeable batteries should not be used because of the
lower capacity and the resulting shorter operating time.
The multimeter must not be operated when it is open, i.e. with an open battery compartment or when the battery
compartment cover is missing.
29
Measuring in potentially explosive areas (Ex) or damp rooms or under unfavourable ambient conditions is not
permitted. Unfavourable ambient conditions are: Moisture or high humidity, dust and ammable gases, fumes or
solvents, thunderstorms or thunderstorm conditions like strong electrostatic elds, etc.
For safety reasons, only use measuring lines or accessories which are adjusted to the specications of the multim-
eter when measuring.
The meter must only be operated by persons who are familiar with the required provisions for the measurement and
the possible dangers. Use of personal protection equipment is recommended.
Any use other than that described above will lead to damage to the product and involves additional risks such as, for
example, short circuit, re, electric shock, etc. No part of this product must be modied or converted!
Read the operating instructions carefully and keep them for later reference.
Always observe the safety information!

This device is CE-compliant and meets the applicable European directives.
Protection class 2 (double or reinforced insulation, protective insulation)
CAT I Measuring category I for measurements at electrical and electronic devices that are not directly supplied
with mains voltage (e.g. battery-powered devices, protective low voltages, signal and control voltages,
etc.)
CAT II Measuring category II for measurements at electrical and electronic devices connected to the mains
supply directly with a mains plug. This category also covers all lower categories (e.g. CAT I for measuring
signal and control voltages).
CAT III Measuring category III for measuring in building installation (e.g. outlets or sub-distribution). This category
also covers all lower categories (e.g. CAT II for measuring electronic devices). Measuring operation in
CAT III is only permitted with measuring prods with a maximum free contact length of 4 mm or with cover
caps above the measuring prods.
CAT IV Measuring category IV for measurements at the source of the low-voltage installation (e.g. main distribu-
tion, building handover points of the energy suppliers, etc.), and outdoors (e.g. work at earthing cable,
outdoor line, etc.). This category also contains all lower categories. Measuring operation in CAT IV is only
permitted with measuring prods with a maximum free contact length of 4 mm or with cover caps above
the measuring prods.
Earth potential
For safety and approval reasons, unauthorised conversion and/or modication of the device are not permitted.
Consult an expert when in doubt as to the operation, safety or the connection of the device.
Meters and accessories are not toys and have no place in the hands of children!
In commercial institutions, the accident prevention regulations of the Employer’s Liability Insurance Association for
Electrical Systems and Operating Materials are to be observed.
In schools, training centres, computer and self-help workshops, handling of meters must be supervised by trained
personnel in a responsible manner.
Ensure before every measurement that the meter is not set to another measuring range. Also observe that the
HOLD button has not been pushed at the beginning of the measurement (display with the HOLD button pushed:
“H”). If the HOLD function is activated before commencement of the measurement, no measured value is displayed!
31
When using the measuring lines without cover caps, measurements between the meter and
the earth potential must not be performed above the measuring category CAT II.
When measuring in the measuring category CAT III, the cover caps must be pushed onto the
measuring prods to avoid accidental short circuits during measurement.
Push the cover caps onto the measuring prods until they latch. To remove, pull the caps from
the prods with a little force.
The measuring prods have to be removed from the measured object every time the measuring range is changed.
The voltage between the connection points of the meter and earth potential must not exceed 600 V DC/AC in
CAT III.
Be especially careful when dealing with voltages higher than 33 V alternating (AC) or 70 V direct voltage (DC)! Even
at these voltages it is possible to receive a potentially fatal electric shock if you touch electrical conductors.
To avoid electric shock, make sure not to touch the connections/measuring points to be measured directly or
indirectly during measurement. Never reach beyond the noticeable grip area marks at the measuring prods during
measurements.
Check the meter and its measuring lines for damage before each measurement. Never carry out any measurements
if the protecting insulation is defective (torn, ripped off etc.). The enclosed measuring cables have a wear indicator.
When they are damaged, a second insulation layer in a different colour becomes visible. The measuring accessories
must no longer be used and must be replaced.
Do not use the multimeter just before, during or just after a thunderstorm (lightning! / high-energy overvoltage!).
Make sure that your hands, shoes, clothing, the oor, circuits and circuit components are dry.
Never operate the product in direct proximity of:
- strong magnetic or electromagnetic elds
- Transmitter aerials or HF generators.
This could affect the measurement.
If you have reason to believe that the device can no longer be operated safely, disconnect it immediately and make
sure it is not operated unintentionally. It can be assumed that safe operation is no longer possible if:
- the device shows visible damage
- the device no longer functions
- the device was stored under unfavourable conditions over an extended period of time or
- following considerable stress during transportation.
Do not switch the meter on immediately after it was 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 the packaging material lying around carelessly since such materials can become dangerous toys in the
hands of children.
Also observe the safety information in each chapter of these instructions.

6. PRODUCT DESCRIPTION
The multimeter (referred to as DMM in the following) indicates measured values on a digital display that can be
illuminated. The measured value display of the DMM comprises 2000 counts (count = smallest display value).
The meter can be used for do-it-yourself or for professional applications up to CAT III.
There are transport protection caps in the angled plugs of the enclosed measuring lines. Remove them before push-
ing the plugs into the meter sockets.
At the rear, there is an unfolding setup bracket (8) with which the DMM can be set up inclined. This makes it easier
to read the display.
An automatic deactivation function switches off the multimeter independently if it is not used for an extended period.
This protects the battery and extends its service life.
Every time the dial switch is pushed and the function is switched, there will be a beep for conrmation.
Dial switch (4)
The individual measuring functions and ranges are selected via a dial switch.
If the multimeter switch is set to “OFF”, the meter is switched off. Always turn the meter off when it is not in use.
