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.
2 Your weighing machine 2.1 Construction and functions 2.1.1 Construction of the weighing machine The weighing machine consists of the weighing machine body (1), the scale-pan (2), the adapter (3) and this operating manual. Figure 2.

2.2 Application, conformity 2.2.1 Correct use of the weighing machine The weighing machine may only be used for the weighing of solid-materials and of liquids filled into secure containers. The maximum allowable load of the weighing machine must never be exceeded, otherwise the weighing machine may be damaged.
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 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 and add the weighing pan 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.
3.6 Leveling the weighing machine To function properly, the balance must be precisely horizontal. The balance is fitted with one bubble level. and adjustable feet for level-control, with the aid of which it is possible to compensate for small height differences and / or any unevenness in the surface on which the balance is positioned. The screw feet must be adjusted so that the air bubble is precisely in the center of the sight glass of the bubble level (see Fig.
4 Working with the application menu using the Intelligent Key-Pad 4.1 Display messages and key functions 4.1.1 Display messages: 1. The WEIGHT DISPLAY indicates the gross or net weight on the weighing pan. 2. The UNIT WEIGHT DISPLAY indicates the average or set unit piece weight. 3. TOTAL DISPLAY is the accumulated total pieces on the weighing machine. 4. LOW SAMPLE INDICATOR activates in the display when the sample number is not significant enough to allow accurate counting. 5.
7. [CE] KEY is used for canceling the numeric setting data or cancels the previous unit weight data. 8. [QTY/SET] KEY is used for the alternation of changing normal counting and quantity check operation. 9. [M+] MEMORY KEY is used when accumulating the count data; this data is memorized by pressing this key and can be accumulated up to 99 times. 4.
4.2.2 Advanced piece counting functions 4.2.2.1. Alarm To avoid counting errors, the weighing machine has a useful alarm function to inform the operator of any counting error in case of low sample size or low sample weight. 4.2.2.2 Low sample warning The low sample indicator on the display will activate if the total weight of sample is below the limit value. To rectify, press CE key. Use a larger sample size (more weight), key in sample size on the numeric keypad and press SAMPLE/UNIT. 4.2.2.
4.2.2.7 Activating the acoustic signal When the scale is turned off, press and hold [UNIT WEIGHT] key to turn on the scale, press [QTY/SET] to select activate(b-ON) or inactivate(b-OFF) the function of the beeper. 4.2.2.8 Activating the display backlight When the scale is turned off, press and hold [UNIT WEIGHT] key to turn on the scale, press [ZERO] key to select L-ON, L-AU(for auto) or L-OFF for the backlight function. 4.2.2.
5 Calibration - Using an External Calibration Weight: Calibration is required when the weighing machine is initially installed or if the scale is moved to a substantial distance from the original location. 10 minutes warm up of scale is always needed before calibration. Single segment calibration (recommended): Turn the scale on and then turn it off.
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.
