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.
3.3 Assembling your weighing machine The weighing machine is delivered in partly dismantled condition. Assemble the individual components in the following sequence: Place the unit holder in position. Insert the power adapter cable plug into the socket at the rear of the balance. 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.
4 Working with the application menu using the Intelligent Key-Pad 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.

4.2.3 Working mode settings - Press & hold UNIT and HOLD keys, then press ON/OFF key to turn on the scale - The display will show Ani. Su, press UNIT key to enter, press ZERO key to select ON( means animal weighing mode) or OFF ( means normal weighing mode), press HOLD key to confirm. - Press HOLD key again, display will show Ani. Kd, press UNIT key to enter, press ZERO key to select anti-shock range between 50, 100, 200 and 400, press HOLD key to confirm.
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 LVS / LVS-XL and LC-VS series are calibrated at the factory.
6 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 separated from the power supply (remove power adapter plug from socket). Also ensure that the balance cannot be reconnected to the power supply during the work by a third party. Take care during cleaning that no liquid penetrates into the appliance.
7 Transport, storage 7.1 Transportation and shipping of the weighing machine Your weighing machine is a precision instrument. Treat it carefully. Avoid shaking, severe impacts and vibration during the transportation. Take care that there are no marked temperature fluctuations during the transportation and that the weighing machine does not become damp (condensation). 7.
