Safety
Representations and symbols
Important instructions, which involve safety, are highlighted with the appropriate mark:
Safety recommendations
When using the weighing equipment in surroundings with increased safety
requirements, the corresponding regulations must be observed.
The weighing scale may only be used with the power adapter supplied.
Before connecting the power adapter to the scale, the user must ensure that the
operating voltage stated on the power adapter is compliant with the mains voltage.
If not, please contact Customer Service at the address above.
If the power adapter or its cable is damaged, the weighing scale must immediately be
disconnected from the electricity supply (pull out the power adapter).
If there should be any reason to believe that it is no longer safe to operate the scale, it
should be immediately unplugged from the electricity supply (pull out power adapter)
and secured against inadvertent operation.
In carrying out maintenance work, it is essential to follow the recommendations set out
in maintenance and servicing.
The weighing scale must not be operated in an area subject to explosion risks.
Care must be taken when weighing liquids to ensure that no liquid is spilled into the
inside of the scale or into connections on the rear of the equipment or the power
adapter. If liquid is spilled on the scale, it must immediately be unplugged from the main
electricity supply (pull out power adapter).
The weighing scale may be operated after it has first been inspected by a service
technician.
These operating instructions must be read by each user and should be easily
accessible at the workplace at all times.

Application & Conformity
The weighing scale may only be used for the weighing of solid-materials and of liquids
filled into secure containers.
The maximum capacity load of the weighing scale must never be exceeded, otherwise
the weighing scale may be damaged.
In using the weighing scale in combination with other devices as well as with devices
produced by other manufacturers, the appropriate regulations for the safe use of the
relevant attachments and their application in accordance with instructions must be
observed.
The weighing scale has been manufactured and tested in accordance with the
standards and recommendations set out in the declaration of conformity.
The power adapter supplied for the weighing scale complies with the appropriate
electrical protection class.

Rev 2, 09.01.16 7
Getting Started
The scale is packaged in an environmentally-friendly carton, which provides optimum
protection for the balance during transportation.
We suggest that you keep the original packaging in order to avoid damage if you are
shipping or transporting the scale to a different location. It is also the best way to keep it
in the best conditions if it will not be used for an extended period of time.
In order to avoid damage, please follow the instructions provided below, when
unpacking the scale:
Unpack the scale carefully.
When outside temperatures are very low, the scale should be stored for a couple
hours and kept in its box in a dry room at normal temperature, so that no
condensation settles on the unit when opening the box.
Check the scale immediately after unpacking for any external visual damage. If
there is any damage on scale, contact customer service immediately.
If the scale is not to be used immediately after purchase, it should be stored in a
dry place where fluctuations in temperature are low. (Reference pg.).
Read through these operating instruction, before you work with the unit and pay
attention to the Safety recommendations (reference Safety pg. 6).

Calibration
When to calibrate
If the scale is inaccurate, calibration may be desired when the scale is first set up for
use, or if the scale is moved to a different altitude or gravitation. This is necessary
because the weight of a mass in one location is not necessarily the same in another
location. Also, with time and use, mechanical deviations can occur.
How to calibrate
Note: calibration value must be 100KG that you have set.
1. Press and keep 【UNIT】key then press ON/OFF key to turn on the scale,
the display will show CAL then AD value.
2. Press 【UNIT】key, the display will show flashed calibration weight. Place the shown
weight then press 【UNIT】key, the display will show ------- then AD value.
3. Take off calibration weight then turn off the scale. Calibration is finished.
If calibration is repeatedly incorrect then: 1) Replace the batteries, 2) Try a more stable
surface or vibration and interference free location.

Rev 2, 09.01.16 12
Maintenance and service
The weighing machine must be treated carefully and cleaned regularly. It is a precision
instrument.
For maintenance-work, the balance must be disconnected from the power supply
(remove power adapter plug from socket). Also ensure that the balance cannot be
connected to the power supply during the work by a third party.
Make sure that no liquid spills into the scale while performing maintenance work. If
liquid is spilled on the scale, it must be inspected by a service technician.
Regularly perform maintenance to the weighing pan and the weighing pan holder by
removing any dirt or dust from under the weighing pan and on the weighing scale
housing. Use a soft brush or a soft, lint-free cloth, moistened with a mild soap solution.
Never use solvents, acids, alkalis, paint thinners, scouring powders or other aggressive
or corrosive chemicals for cleaning; these substances can cause damage to the
Transport & Storage
Your weighing machine is a precision instrument, treat it carefully. Avoid shaking,
severe impacts and vibration during the transportation. Make sure that there are no
marked temperature fluctuations during the transportation and that the weighing
machine does not become damp (condensation).
If you would like to take the weighing machine out of service for an extended period,
disconnect it from the electricity supply, clean it thoroughly (refer to Maintenance &
Service) and store it in a place which meets the following conditions:
No violent shaking, no vibrations
Minimum temperature fluctuations
No direct solar radiation
Minimum moisture
