1 Safety 1.1 Representations and symbols Important instructions, which involve safety, are highlighted with the appropriate mark: 1.2 Safety recommendations When using the weighing equipment in surroundings with increased safety requirements, the corresponding regulations must be observed. The weighing machine may only be used with the power adapter supplied exclusively for use with the weighing machine.
If there should be any reason to believe that it is no longer possible to operate the weighing machine without danger, the weighing machine is to 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 in Chapter 6 Maintenance and service. The weighing machine must not be operated in an area subject to explosion risks.

3 Getting started with your weighing machine 3.1 Unpacking the equipment The machine is delivered in an environmentally-friendly carton, specifically developed for this precision instrument, which provides optimum protection for the balance during transportation. We suggest that you retain the original packaging in order to avoid transportation damage if re-shipping or transporting the balance and to allow the unit to be stored in the best conditions if it is out of operation for an extended period.
Read through these operating instructions; even if you already have prior experience with weighing equipment, before you work with the unit and pay attention to the Safety recommendations (see Chapter 1 Safety). 3.2 Scope of delivery Inspect delivery for completeness immediately on unpacking all components. Checklist for complete delivery Component delivered present yes / no Weighing unit body Indicator Power adapter Operating manual 3.
3.4 Choice of a suitable location The environment in which your weighing machine is used is very important. Air movement, temperature changes, vibrations, direct sunlight, etc. all influence the performance of high precision weighing machines. Therefore, place your weighing machine on a solid, sturdy surface that is free of air currents, vibration and not in direct sunlight. The surface should not be magnetic and should be located away from doors, windows, heaters, air conditioners and fans.
If the operating voltage is not the same as the mains voltage, the power adapter must on no account be connected to the mains supply. Contact customer service. 3.6 Calibrating the weighing machine Since the Earth’s gravity is not the same everywhere, each balance must be adjusted to compensate for the gravity differences at each location in accordance with the underlying physical weighing principles.
4.1 Display messages and key functions 4.1.1 Display messages: Low battery indicator Negative value indicator Zero indicator 4.1.2 Key Functions: 1. The ON/OFF key is to turn the Scale On or Off 2. The HOLD key is to store the weight value. 3. The UNIT key is to toggle different weighing units. 4. The ZERO key: Zero feature if load weight below 4% of full capacity; Tare feature if load weight between 4% to 100% of capacity. 5. The PRINT key is to send data to external device through RS232 connector. 4.

4.2.2.2 Setting Backlight Press and hold HOLD key, then press ON/OFF key to turn on the Scale, display will show “A ON” or “A OFF”, Press UNIT key, display will show “L ON”, “L OFF” or “L AU”, press ZERO key to select back light On, Off or Au(auto) 4.2.2.
between 0.5, 3, 5 and 10, press HOLD key to confirm. - Press HOLD key again, the display will show Ani. Ft, press UNIT key to enter, press ZERO key to select filter time between 1, 2, 3 and 4, press HOLD key to confirm. *** This is the filter time, 1s, 2s, 3s or 4s that will take to display the weighing. Weighing will be more accurate if the user chooses 4 second (longer displaying time), but not so accurate if 1 second (faster displaying time) is chosen. Press ON/OFF key to turn the scale off. 4.2.

5 Calibration - Using an External Calibration Weight Calibration is generally required when the weighing machine is initially installed or if the weighing machine is moved to a substantial distance from the original location. 30 minutes of warming up of the scale is always needed before initial calibration. A reminder when operating our larger capacity scales: The scales of the LDS series are calibrated at the factory. Usually no recalibration is necessary unless major inaccuracies are observed.
increase the value of the flashing digit, press HOLD key to confirm, it will show CAL again.
The connections on the rear of the appliance and the power adapter may not come into contact with liquids. Regularly dismantle the weighing pan and the weighing pan holder and remove any dirt or dust from under the weighing pan and on the weighing machine housing with a soft brush or a soft, lint-free cloth, moistened with a mild soap solution. The scale and the holder can be cleaned under running water. Take care that both parts are completely dry before they are re-installed on the scale.
7.2 Storage of the weighing machine 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 (see Section 6 .Maintenance and servicing.
