Alarms
•Overload
•When the load on the platform is over the maximum capacity
•Take the load off immediately!
•Unit weight
•“LackofUnitWeight”: Average unit weight is not sufficient for accurate counting
•Re-calibrate the sample weight using more samples.
•Lack of number of sample
•If the total weight of sample is below limit value
•Low battery
•When appears on the display, you're requested to recharge the scale over12 hours. When
the scale is recharging, the recharging symbol will flash.
•Charging light
•When the battery is charging, the charging light appears in red. When full, green.

Preparation
1. Carefully remove contents from the package which may include fragile parts.
2. Carefully assemble the scale by placing the scale pan.
3. Place the scale in a firm and flat surface, and avoid location where the scale
maybe subject to vibration, sunlight, airflow, contact with water, and strong
electromagnetic wave.
4. Level the scale by using the bubble level indicator (if available) and adjusting
the feet of the scale.
5. Locate scale in the following condition:
1. Temperature : 0oC ~ 40oC
6. Plug in the scale to a surge protected power outlet if using the AC adapter. If
using rechargeable batteries, fully charge the rechargeable batteries before use.
7. Turn the scale on and wait for it to finish initialization (i.e. when the display
shows a weight of 0).
8. Let the scale warm up for 1 minute before use.
9. Make sure any weight placed on the scale is not beyond the rated maximum.
10.If scale is not used for an extended period of time, disconnect all power.
