zDo not let children play with the measuring
device. They can injure themselves on the
sharp measuring edges or swallow the
battery/battery compartment lid.
zMeasure very carefully on sensitive sur-
faces, in order to avoid leaving scratch
marks.
zDo not connect any voltage to any part of
the digital caliper gauge (e.g. for engrav-
ing with an electric pen), as the switch
could otherwise be damaged.
Functions
zThe zero setting in any position simplifies
stage measurements. Press the zero
gauge (ZERO) in order to define the zero
point. This enables difference measure-
ments (negative measurements are dis-
played with a “-”).
zInch/mm conversion in any position. Press
the mm/inch key in order to display the
measurement result in a different unit.
zFor very precise measurements, the cali-
per gauge can be operated particularly
precisely using the fine-tuning wheel.
zAutomatic and manual power switch-on/
switch-off.
Maintenance/Storage
1. Prior to use, clean the surface of the
measuring scale with a dry and clean
cloth (or saturated with cleaning oil). Pro-
tect the measuring scale from water or liq-
uid.
2. Only clean with a dry cloth and some
cleaning oil; do not use any water, solvent
or abrasive detergent.

3. Remove the battery if the instrument is
not being used for a longer period of time.
4. Preferably store the caliper gauge in the
case in order to provide optimum protec-
tion.
Use
1. Preparation:
1. Wipe of the surface of the measuring
scale and clean the measuring surfaces.
2. Loosen and move the safety screw,
check the ease of movement over the en-
tire measuring range.
3. Insert battery as described on page 10.
4. Switch on device and check whether the
LCD display and all keys function fault-
lessly
2. Measurement:
1. Press the On/Off key in order to switch on
the power. The device is also switched on
by activating the caliper gauge.
2. Press mm/inch key in order to select the
required unit of measure.
3. Move the slider until the outer measure-
ment surfaces touch lightly, then press
the zero gauge (ZERO) in order to start
the regular measurement. With the safety
screw, you can fix the caliper gauge in or-
der to ensure the measurement result.
4. Press the On/Off key in order to switch off
the power; if the slider is no longer used
after the end of the measurements, the
display will switch off after approx.
4-5 minutes.

Inserting the battery
An abnormal display (flashing numbers or
no display at all) indicates a low battery volt-
age and the battery must be replaced.
Remove the battery lid in the direction of the
arrow and insert the battery or replace a
used battery with a new one.
When inserting, pay attention to the correct
polarity, the positive terminal of the battery
must be pointing upwards. Close the lid
again after inserting the battery. If the
battery that has been purchased on the
market does not work faultlessly (voltage
too low due to being stored for too long and
self-discharge of the battery), contact the
after sales support hotline on 1800 269 981.
- After inserting the battery, the
caliper gauge requires several
seconds (approx. 5-6 seconds)
in order to set itself. The caliper
gauge can only be switched on
again after the end of the setting
process.
- Reset the zero point of the
measurement after replacing the
battery.
Instructions for batteries
zNever attempt to recharge non-recharge-
able batteries.
This is an explosion hazard!
zKeep batteries away from children, do not
throw them into fire, do not short-circuit
batteries and never dismantle batteries.
zImmediately contact a doctor, if a battery
has been swallowed.

zClean the battery and device contacts
prior to insertion, if required.
zImmediately remove depleted batteries
from the device. This increases the risk of
battery leakage.
zDo not expose batteries to any extreme
conditions, e.g. on radiators, direct sun-
light! This increases the risk of battery
leakage.
zFailure to comply with the instructions
above could result in batteries being dis-
charged beyond their final charge voltage
and leaking. Remove batteries immedi-
ately, in order to avoid damage.
zAvoid contact with the skin, eyes and mu-
cous membranes. Immediately rinse ar-
eas affected by the battery acid with plenty
of clear water and immediately contact a
doctor.
zRemove the batteries from the device in
the case of longer periods of disuse.
Battery disposal

to the collection centre of their local council
or to retailers. All batteries and rechargeable
batteries can thereby be disposed of in an
environmentally friendly manner.

Environmental protection/
disposal
In the interest of the environment, dispose of
the caliper gauge properly. Do not throw the
caliper gauge into household waste, but
rather, submit it to a collection centre for
electrical waste.
Remove the battery beforehand and
dispose of it properly in a collection contain-
er for batteries.
The packaging materials are also raw mate-
rials! Therefore, submit them for recycling.
Your responsible local council will inform
you about addresses and opening times of
collection centres.
