Tare function
To weigh liquids or bulk goods, weighing vessels can be used. To correct for the weight of the weighing
vessel during measuring, the tare function can be used.
The total weight of weighing vessel and weighing object must not exceed the max.
weight of 20 g. Thus, use light plastic or paper vessels.
Proceed as follows to weigh:
Switch on the scale, and wait until the zero indication is displayed.
Place the empty weighing vessel on the weighing plate (2) and wait until the displayed value is constant.
Then briefly press the “TARE” button (6). The displayed value is set to zero. Thus, the weight of the weighing
vessel is not included in the subsequent measurement. The active tare function is indicated by a small triangle
in the left display frame (-> T <-).
Remove the weighing vessel and fill with the material to be weighed.
Place the filled vessel carefully on to the weighing plate (2). Dynamic measurements, i.e. by filling with material
is not feasible, as this leads to erroneous measurements.
Wait for approx. 5 seconds, until the reading is constant. The measurement result is displayed.
The Tare function can be switched off by pressing the „TARE“ button again.
Press the „ON/OFF“ button to turn off.
Additive weighing function
The additive weighing function enables the adding of subsequent measurements. With this function individ-
ual weights of max. 20 g each, up to 99.999 g can be added together. This makes it possible to create the
precise mixture of different substances.
Proceed as follows to weigh:
Switch on the scale, and wait until the zero indication is displayed.
Open the flap lid (1).
Place the first object to be weighed carefully on the weighing plate (2). Wait for approx. 5 seconds, until the
reading is constant. Press and hold the „ADD UP“ button (5) for approx. 2 s. The measured value will be
saved. Remove the object from the scale. Wait until zero is shown on the display.
Place the next object to be weighed carefully on the weighing plate (2). Wait for approx. 5 seconds, until the
reading is constant. Press and hold the „ADD UP“ button (5) for approx. 2 s. The measured value will be
added up, displayed and saved. Remove the object from the scale. Wait until zero is shown on the display.
Proceed with this step for your other additive measurements.
The total weight can be read out for approx. 2 seconds after the last additive measurement. If the total weight
of 99.999 is exceeded, the message „Err“ is shown on the display.
To delete the total weight saved, press and hold the „ADD UP“ until „CLF“ appears on the display, while the
scale and zero indication are switched on.
Press the „ON/OFF“ button to turn off.
Adjustment
The pocket scale should be re-adjusted after a while, to avoid measuring inaccuracies. For the adjustment,
a reference weight of 20 g is included in the delivery.
To carry out the adjustment, proceed as follows:
Switch the scale off and place it on a level and stable surface.
Press, and hold, the „TARE“ button for approx. 2 seconds, until a numerical value appears on the display. An
exact value is not relevant.
Wait until the value has stabilised and press the „TARE“ button again.
„ZEro“ is shown on the display, and then the calibration value „20“.
Place the reference weight of 20 g on the scale plate and then press the „TARE“ button.
In the display „PASS“ will appear. Remove the reference weight from the scale and switch the scale off. The
scale is readjusted.
☞
Treat the reference weight with great care. If possible, only touch it with gloves. Any soiling or
damage leads to weight variations, and consequently to inaccuracies during the adjustment.
Automatic cut-off
To save batteries, and to increase the operating time, the pocket scale switches off automatically after
approx. 3 - 4 minutes, if no keystroke is performed and no weight is measured.
Press the „ON/OFF“ button, to switch the scale on again.
Maintenance and Cleaning
Apart from occasional cleaning and battery replacement, the device requires no servicing.
Use a soft, dry, antistatic and lint-free cloth for cleaning. Do not use abrasive or chemical cleaners or petrol.
Disposal
Electronic products are raw material and do not belong in the household waste. When the device
has reached the end of its service life, please dispose of it, according to the current statutory
requirements, at your local collecting site. Disposing of the device in the household waste is
prohibited.
Disposal of Used Batteries
As a consumer, you are required (Battery Ordinance) to responsibly dispose of all used bat-
teries and rechargeable batteries; it is forbidden to throw them away with the normal
household waste!
You can dispose of your used batteries/rechargeable batteries free of charge at your commu-
nity’s collection point or any place where batteries/rechargeable batteries are sold!
You thus fulfil the legal requirements and make your contribution to protecting the envi-
ronment!
