BEFORE USING THE SCALE
To enable you to use this scale correctly, we suggest that you read this manual carefully.
1. Do not use scale in areas with excessive water and dont spray the scale or indicator with water when cleaning. Remove all water from the scale and indicator with a clean dry cloth.
2. The load placed on the platform must not exceed the maximum weighing capacity of the scale.
3. Keep the scale away from high temperatures and damp conditions.
4. If the scale is not going to be used for some time, please clean it and store it in a plastic bag in dry conditions. A desiccant sachet may be included to prevent moisture build up.
5. If the scale is not going to be used for some time, the internal rechargeable battery should be recharged every three months.
6. Before using the scale after a long period of storage, please ensure that the internal battery is fully charged. NOTE: Care should be taken not to leave the internal battery on charge for too long, as this may decrease the life of battery.
PREPARING TO USE THE SCALE
1. Locate the scale on a firm level surface free from vibrations for accurate weight readings.
2. Adjust the four levelling feet to set the scale platform level using the spirit level bubble located on the scale platform frame.
3. Avoid operating the scale in direct sunlight or drafts of any kind.
4. Remove any weight that might be on the scale platform before the scale is switched on.
5. Once the scale has been switched on, it will go through a LCD display test and then re-zero to be ready for use.
6. The scale requires 15~20 minutes warm up before operation to ensure best accuracy.
7. Please note when the symbol is shown on the display, the internal battery needs to be recharged.
8. All goods weighed should be placed in the centre of the platform for accurate weighing.
The footprint of the goods being weighed should not overhang the edges of the platform.

3. POWER CONSUMPTION
1. The power consumption is around DC 20 mA (system + load cell), the rechargeable battery
can be used up to 200 hours.
2. The power consumption is around DC 67 mA (system + load cell + backlight), the
rechargeable battery can be used for 60 hours approximately.
3. The power consumption is around DC 71 mA (system + load cell + backlight + RS-232), the
rechargeable battery can only be used for 56 hours approximately.
4. LOW BATTERY WARNING
Please note when the symbol is shown on the display, the internal battery needs to be
recharged.
v The scale will power off automatically without recharging after the low battery symbol
shows upon for 20 to 30 hours (3 to 5 hours if the backlight is active) on the display. As a
recommendation, the scale must be fully recharged before operating the scale again.
