2. Purpose
To develop a low cost LCD display counting scale which caters to OIML, UL, EU Standard and meets requirement of
major customers.
3. Features
* Low cost counting scale.
* Quick response to weight changes.
* Capacity : 500g; 1kg; 2.5kg; 5kg; 10kg; 25kg; 50kg
* Resolution : Display Resolution 1/10,000.
Internal Resolution 1/1000,000.
* Rechargeable Battery backup for 24 hours of continuous usage (optional).
* Intelligent power control
A. When AC power is available, scale will use AC power only whatever rechargeable battery is installed or not.
When AC power is shut off, scale will use battery automatically.
B. When scale works on rechargeable battery, if the battery is weak, the battery indictor will light up.
When the power from battery becomes low such that the scale can not compute accurately, all Displays will
shut off except the Battery indicator. The power is then shut off completely after 1 minute.
C. Scale detects rechargeable battery voltage and control battery charge process automatically.
The battery charge indicator lights up when rechargeable battery is being charged.
* Calibration by software.
* Water proof keyboard and splash proof housing.
* 24 switch keys
- ON/OFF key.
- 10 Numeric keys.

* RS-232C interface for data communication and printer connection.
- Gross Weight, Tare Weight, Net Weight, Unit Weight, Count, PLU code, Product Description, Product Lot No.,
Accumulated count.
* Two scale channels, one for built-in platform, another for remote platform.
* External printer connectible (RS-232C)
- Label printer : DIGI GP-460R
- Bar code printer : ZEBRA LP-2844
