2. INTRODUCTION
 T e BWS series weig ing indicator amplifies signals from a load cell, t en
converts it to digital data and displays it as a mass value number
 It is suitable for general weig ing or more specialized applications suc as
c eck weig ing, animal weig ing and accumulation applications
 Can be connected to a printer, PC, or scoreboard
 Large LCD wit w ite LED back lig t displays
Charging
• To c arge t e battery, plug cord into power outlet. T e scale does not need
to be turned on, to c arge.
• T e battery estimated c arge time to full capacity is 12 ours.
• An LED to indicate t e status of battery c arge is located on t e left side of
t e Display. W en t e scale is plugged into a power source t e internal
battery will be rec arging. If t e LED is green, t e battery as a full c arge.
If it is red, t e battery is nearly disc arged and if yellow, t e battery is
being c arged.
• Verify t at t e AC power outlet is properly protected.
Note: Please charge the battery before using the scale for the first time.

5. OPERATION
Initial Start-up
Warm-up time of 15 minutes elps stabilizes t e measured values after switc ing
on.
5.1. Basic Operation
1. Power On/Off:
Switc on t e BWS by pressing t e key.
T e display is now switc ed on and t e start-up test as started, if wanting
to switc off, press t e key again.
2. Zero:
Environmental conditions can lead to t e BWS not being exactly zero
even if t e weig ing platform is clear of a weig t. However, you can set
t e display of your BWS to zero any time by pressing t e key and
t erefore ensure t at weig ing starts at zero.
3. Tare:
T e weig t of any container can be tared by pressing button so t at
wit subsequent weig ing t e net weig t of t e object being weig ed is
always displayed.
• Load weig t on t e platform.
• Press key. Zero is displayed, and tare is subtracted.
• Remove weig t from t e platform. Tared weig t is displayed. T e BWS
can only store one tare value. (see parameter P4) It will be s own wit a
minus value.
• Press to c ange between gross weig t and net weig t.
• To clear t e tare value, remove t e load and press key. Zero is
displayed, tare weig t is cleared.
4. Select Unit: (Units not being used can be disabled see parameter 6)
Press t e key, to c ange units kg/g/lb/oz.
