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.
The weighing machine must not be operated in an area subject to explosion risks. Keep this weighing machine away from water – this machine is NOT water resistant. Shock, injury and electrical damage can occur if used in a wet location. Care must be taken when weighing liquids to ensure that no liquid is spilled into the inside of the weighing machine or into connections on the rear of the equipment or the power adapter.

The maximum allowable load of the weighing machine must never be exceeded; otherwise the weighing machine may be damaged.
The power adapter produced for the operation of the weighing machine and intended exclusively for this application complies with the appropriate electrical protection class. 2.3 Data and parameters 2.3.
Check the weighing machine immediately after unpacking for externally visible damage. If you should find transport damage, please inform your service representative immediately. If the unit is not to be used immediately after purchase but rather at a later time, it should be stored in a dry place where fluctuations in temperature are as minimal as possible. (See Chapter 7 Transport, storage).
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. To summarize: Put the weighing machine on a solid, firm and preferably vibrationproof, horizontal base Make sure that the weighing machine cannot be shaken or knocked over Protect from direct solar radiation Avoid drafts and excessive temperature fluctuations 3.
measurements, the machine must again be carefully leveled after each relocation. Fig. 1 Correct leveling with the aid of the bubble level and adjusting feet. 3.7 Calibration of the weighing machine Since the Earth’s gravity is not the same everywhere, each weighing machine must be adjusted to compensate for the gravity differences at each location in accordance with the underlying physical weighing principles.
4 Working with the application menu using the Numeric Key-Pad 4.1 Display messages and key functions 4.1.1 Display messages 1. The STABLE icon indicates when the readings are stable. 2. The ZERO icon indicates when the weights are tared to zero. 3. The LO-BAT icon indicates when the battery is running out of power. 4. The PCS icon indicates when the pieces counting function is applied. 4.1.2 Display & Key Functions 1.
3. TOTAL DISPLAY is the accumulated total pieces on the scale. 4. The ZERO INDICATOR turns on when the weighing machine is in Zero position. 5. The TARE INDICATOR turns on when this function is used. 6. LOW SAMPLE WEIGHT turns on when the sample number is not large enough for accurate counting. 7. LOW UNIT VALUE turns on when sample unit weight is not heavy enough for accurate counting. 8. NUMERIC (0-9) KEYS are used for setting numeric data for sample number, sample weight or to limit the HI / LO settings.
18. Press the TOTAL key to switch between normal counting and recalling memory data. 4.1.3 Function setting - Turn off the weighing machine using the hard switch located on the bottom of the weighing machine. - Press and hold UNIT WEIGHT key and then turn on the weighing machine. The display will show “------“ and then “b = XX” (beeper), on the first line, A-XX (auto off) on the second line and “L = XX (backlight) on the third line. - Press the QTY/SET key to toggle between activating the beeper on or off.
5 Operation 5.1 Tare 5.1.1 Clearing the tare weight - Place the empty container on the platter. Press the TARE key. The display will show 0.00000. - When the container is removed from the platter, the WEIGHT display will show a minus (-) weight value which is the weight of the container. 5.1.2 Clearing the previous tare weight - Remove weight from the platter and then press the TARE key. The Tare indicator will turn off and the WEIGHT display will return to Zero. 5.2 Sample setting 5.2.
Press the CE key again to cancel the previous unit weight and sample setting. 5.3 Alarm function - To avoid counting errors, this scale has a useful alarm function to inform the operator of a counting error in the event of low sample size or low sample weight. - The Low Sample Weight cursor on the display will turn on if the total weight of the sample is below the limit value. The scale will start counting but the error may be high. - Press the CE key.
- Press the QTY/SET key to enter the quantity alarm menu. - Press the ZERO key to turn on the check weighing. Display will show CH=ON. Press the ZERO key again and the display will show CH-OFF which means the quantity alarm function has been turned off. - To set the lower and upper count limit, press the TARE key to select the hi/lo limits. For example, “L = 990,” press 990 on the numeric keypad, then TARE to switch over to: H = 1010,” press 1010 on the numeric keypad.
place the calibration weight on the platter. Press ZERO to calibrate. Once the stable indicator light is displayed, press the ZERO key again. The second line of display will now show 00000. Calibration is now complete. NOTE: The ideal calibration test weight is between 2/3 capacity to full capacity in order to get the most accurate weight after calibration. Turn off the power, then turn it back on again. Place a weight on the platter to ensure weighing is correct. If not, repeat the above steps.
7 Maintenance and service The weighing machine must be treated carefully and cleaned regularly. It is a precision instrument. For maintenance-work, the machine must be separated from the power supply (remove power adapter plug from socket). Also ensure that the weighing machine cannot be reconnected to the power supply during any work by a third party. Take care during cleaning that no liquid penetrates into the weighing machine.
Take care that there are no marked temperature fluctuations during the transportation and that the weighing machine does not become damp (condensation). 8.2 Storage 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.
