and will result in erroneous measurements.
The pocket scale is powered by batteries. The voltage supply is delivered by 4 micro batteries (AAA). These
are not enclosed.
Do not operate the scale where there is a risk of explosions. Do not use the scale for humans or animals, for
medical purposes, or in commercial trade for determining prices.

Getting started
Inserting/Replacing the Batteries
The pocket scale is powered by batteries. If you use the product for the first time, or if the battery replace-
®
ment symbol (A) appears on the display, you have to insert new batteries in the battery compartment.
To insert and replace the batteries, proceed as follows:
°
Close the flap lid (1).
Remove the lid of the battery case on the rear side (8).
Remove the used batteries from the battery compartment.
Version 01/11
Insert four new micro batteries (AAA) with the polarity aligned. Take note of the polarity information in the
battery compartment.
Close the battery compartment carefully.
Do not mix old and new batteries. Always replace all the batteries at the same time, otherwise
the batteries discharge each other. Always use batteries of the same type and brand.
You can acquire suitable micro batteries under following order number:
order no. 65 23 47 (package of 4, please order 1x).
Do not leave flat batteries in the device. Even batteries protected against leakage can
corrode and thus release chemicals that could be detrimental to your health or destroy
the device.
Remove the batteries, if the appliance is not to be used for long while, to prevent leaking.
Leaking or damaged batteries might cause severe burns if they come into contact with
the skin. Use appropriate protective gloves in such case.
Do not leave batteries lying around carelessly. They might be swallowed by children or
pets. If swallowed, consult a doctor immediately.
Make sure that the batteries are not short-circuited. Do not throw batteries into a fire.
Batteries (non-rechargeable) must not be recharged. Danger of explosion.
Weighing
The maximum weighing range of 20 g must not be exceeded. Avoid thermal fluctuations
during weighing; this may lead to erroneous measurements.
Preparation
Place the pocket scale on a stable, level surface and open the flap lid.
Press the „ON/OFF" button (7), to switch on the scale. After a brief testing phase (all digits are displayed),
the scale performs the zero setting (display „0.00 or 0.000"). The scale is now ready for use. Avoid vibrations
and loading of the weighing plate during this phase. When the check has been completed successfully, a cir-
cle appears in the lower left corner (-> o <-) indicating stable measuring conditions, as well as the reading
„0.00" or „0.000".
If the automatic zero setting has failed, remove any weights that might be placed on the weigh-
ing plate and make sure it is on an even surface. Avoid vibrations and draught. Turn the device
off and then on again.
If these measures do not bring the desired result, the zero setting can be carried out manually
using the „TARE" button (6).
Press the „ON/OFF" button to turn off.
Selecting the Weight Unit
The pocket scale provides the option of weighing with 4 different weight units.
Gram (g), ounce (oz), pennyweight (dwt) or carat (ct). Press the „MODE" button (4), when the scale is
switched on. Each press switches the weight unit. The selected unit is shown by a line, on the right side of
the display. The last selected unit remains selected after switching the device off.
Weighing
Switch on the scale and, depending on the unit, wait until „0.000" or „0.000" is displayed.
Open the flap lid (1).
Place the object to be weighed carefully on the weighing plate (2).
Close the flap lid to avoid erroneous measurements due to slight air movements. Make sure the weighing
material does not touch the scale housing or the flap lid.
Wait for approx. 5 seconds, until the reading is constant. The measurement result is displayed.
Press the „ON/OFF" button to turn off.
When the measuring range is exceeded, „- - - - -" is shown. In this case, immediately
remove the item to be weighed from the pocket scale, as it may be damaged otherwise.
Remove the object from the scale, immediately after measuring, to avoid damage to the
scale.
