Capacity
not
accurate or
calibration
can’t be
finished
Linearity is not
good
The platform is not laid in level; Four feet are
not laid in level; Moveable leg lock the seal
cover of the foot; Load cell broken; There are
some objects between load cell and scale.
Lay the platform in the same level; Set
the four feet in the same level; Check the
moveable foot; Clear the objects; Replace
the load cell.
Big tolerance
with full corner
The platform is not laid in level; Four feet are
not laid in level; Moveable foot lock the seal
cover of the foot; Load cell broken; There are
some objects between load cell and scale.
Lay the platform in the same level; Set
the four feet in the same level; Check the
moveable foot; Clear the objects; Replace
the load cell.
There is some
problem with
repeating
function
The platform is not laid in level; Bottom dust
proof wash lock the bottom bolt; Broken load
cell; Aging problem with PCB; There is some
objects between load cell and scale.
Lay the platform in level; Calibrate four
feet; Check the dust proof wash; Clear
the objects; Replace the load cell.
Calibration can’t
be finished
The inner code at 0 point is too small or too
big; not enough with the full capacity inner
code; not stable; there is some objects
between load cell and scale body; broken load
cell.
Calibrate the inner code at around
10000 on PCB and calibrate again;
Replace PCB; Clear the objects; Replace
the load cell.
Function
problem
No function with
key button
Key button not work; aging problem of the
apparatus on PCB
Check the button; Replace PCB
Not smoothly
communicating
Communication wire broken; or the interface
apparatus broken
Replace communication wire; Replace
PCB
Battery and Charging
Power is supplied by an internal rechargeable 6V 4Ah rechargeable battery. 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.
