authorized person to change the calibration settings. Ask the
password from your local dealership or from technical support).
NOTE:
A USER-DEFINED UNIT is an additional unit represents the unit defined by the user,
aside from kg or lb. The conversion value is equivalent to the ratio against to its
SYSTEM UNIT.
For example, assuming the scale’s system unit is kg. If the USER-DEFINED UNIT
is equivalent to 1.234 unit per 1kg then after switching to USER-DEFINED UNIT,
the scale should display the 1000kg weight to 1234 user-defined unit.

SYSTEM UNIT
oIn contrast to the DISPLAY UNIT, the SYSTEM UNIT was set before it
leaves the factory. It was set when the scale was calibrated at factory.
oSome models were set to metric scale’s SYSTEM UNIT (kg by
default) while some were set to imperial scale’s SYSTEM UNIT
(lb by default).
To switch between metric and imperial system, refer to the Display Unit Switch
section.
oThe lb indicator w i l l light on after SYSTEM UNIT switches
to lb.
oThe kg indicator will light on after SYSTEM UNIT switches to
kg.
Note: Some models may not have both lb and kg indicator. Some may have lb
indicator or kg indicator only. For models with only one indicator, the light will
turn off when the scale is switch to its alternate measurement unit (either in
kg or lb).
NOTE:
SYSTEM UNIT shall be changed only if the alternate unit will be made
as the new system unit. Most of these scales are calibrated from
factory with imperial unit (lb unit) as the system unit. If you want to
use the metric as the system unit, change the system unit to Un PG
then recalibrate the scale. Recalibration is required for changing
SYSTEM UNIT.
The same process if your scale was set with metric system unit,
switch the system unit to Un Lb then recalibrate.

MAXIMUM CAPACITY
Action
oTo set the scale’s MAXIMUM CAPACITY, select the capacity options.
The parameter value will be multiplied by 1000 to get the maximum
capacity value. For example, if it is set to FS 2 ( see image below) then
the scale will be set to have 2000 lb or 2000kg max capacity (it will not
matter what unit you set at system unit).
ZERO WEIGHT CALIBRATION
Action
