9.1 Troubleshooting 

SYMPTOM 

PROBABLE  CAUSE 

REMEDY 

Will not power on 

Power cord not plugged in or properly 
connected. Power outlet not supplying electricity. 
Battery discharged. Other failure. 

Check power cord connections. Make sure 
power cord is plugged into the power outlet. 
Check power source. Replace batteries. Or 
service required. 

Unable to zero the 
display or will not 
zero when turned on 

Load on scale exceeds allowable limits. 
Load on scale is not stable. 
Load cell damage. 

Remove load on scale.   
Wait for load to become stable.   
Service required. 

Lo.bAt is shown 

Battery is discharged 

Charge battery 

 

 

9.2 Battery and Charging 

Power is supplied by an internal rechargeable 6V lead-acid battery (4Ah). When “Lo.bAt” is displayed, the battery must 
be recharged. Plug in the AC power adapter to recharge the battery. The scale may continue to be used on AC power 
during charging. Full charging time is approximately 10-12 hours.   
Battery life and recharge time will vary with use. Over time, the operating time per each full charge will degrade. If the 
operating time is no longer acceptable, the battery must be replaced. When storing the scale for extended periods, the 
battery must be charged every 90 days to avoid premature performance degradation.
