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 2.1 Your weighing machine 2 1 3 2.1.2 Functions of the weighing machine Final Rev 2013.12.
The DCT Series are high-quality electronic precision weighing machines designed to function as counting scales with the following specifications. Specifications: Model number Capacity Division Weighing pan Size DCT-50 50lb/2lb 0.001 lb/0.00005lb 345x260/114x114mm DCT-100 100lb/4lb 0.002lb/0.
The built-in versatile weighing programs allow you to use the DCT-Series weighing machines not only for accurate weighing but also for components counting.

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 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 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.

Kg: unit of measure 2. lb: unit of measure 3. stb: stable indication 4. zero: ZERO INDICATOR turns on when scale is in Zero position 5. tare: TARE INDICATOR turns on when this function is used 6. LoUW: turns on when sample unit weight is not heavy enough for accurate counting 7. LoWT: turns on when sample number is not enough for accurate counting 8.
9. S1: SCALE 1 working state 10. S2: SCALE 2 working state 11. S3: SCALE 3 working state 12. LoB: low voltage, please charge battery 13. CHG: charged state, red LED lights up when charging, when the battery is fully charged, Red and Green LED lights flash alternately. 4.1.2 Key functions 1. SCALE/SELECT: Press this button to select available counting scale among scale 1, scale 2, and scale 3. You can only choose to use one of them at a time.
12. UNIT WEIGHT is used when setting the known unit weight data into the scale during normal operation. (1/1000kg or 1/1000lb) 13. QTY/SET key is used when wanting to switch between the pieces counting function and quantity check weighing function. 14. NUMERIC (0-9) keys are used for setting numeric data for sample numbers, sample weights or to set a limit for the HI/LO settings. 15. [*] Key is used to change the division when the scale is in SCALE 3 mode. 16.
4.2.1.2 Counting pieces without known sample unit weight - Turn scale on - Wait for "0" to appear on the display. - If necessary, press ZERO key to set the display to “0” - Press SCALE/SELECT key to select SCALE 2, press ENTER to confirm -Put a pre-known number of samples onto SCALE 2, key-in the known number using the numeric keypad.
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. 5.
- Press ENTER to set zero point (UNIT WEIGHT will show CAL-0 flashing for a few seconds and then changes to XXXX to set the calibration weight) - Press [CE] key and then press the corresponding number buttons based off of the amount of weight you are using to calibrate (example: if you are using 1lb to calibrate the scale you would key in 1lb). - Calibration weight will show in the UNIT WEIGHT display. - Press the ENTER key, the UNIT WEIGHT display will show flashing XX and then changes to XX.XXX lb.
- Press CE Key to set the full capacity – key in the number through the numeric keypad - Press (*) to set the division – key in the number through the numeric keypad - Press ENTER to confirm - Now begin the CALIBRATION process: - Press UNIT key to select whether you will calibrate in kg or lb - Press ENTER to set zero point (UNIT WEIGHT will show CAL-0 flashing for a few seconds and then changes to XXXX to set the calibration weight) - Press [CE] key and then press the corresponding number buttons based off
Never use solvents, acids, alkalis, paint thinners, scouring powders or other aggressive or corrosive chemicals for cleaning, since these substances attack the surfaces of the scale housing and can cause damage. Final Rev 2013.12.
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.
