Short press or press and to change digit.
Press and to right scroll digit. Input password
.
Press to confirm password, and enter Scale Configuration.
shows.
Parameters in Scale Configuration are closely related to scale’s metrology performance. It is NOT recommended to change any parameters unless you are authorized from your local representative.
Display Resolution
Press to enter Display Resolution. shows.
Short press or press and to change resolution value.
Display Resolution can be set to: , , ,
, , , , , , , , , , , .
Designed to meet the OIML R76 ’s directive, the scale has the best (default) performance at 2000 to 3000 division.
Auto-Zero Range
Press to enter Auto-Zero Range. shows.
Short press or press and to change range.
Auto-Zero Range can be set to: (disabled), (±2%FS),
(±3%FS), (±4%FS), (±10%FS), (±20%FS),
(±100%FS). It is set to ±20%FS by default.
Upon boot-up, scale automatically zeros.

Manual-Zero Range
Press to enter Manual-Zero Range. shows.
Short press or press and to change range.
Manual-Zero Range can be set to: (disabled), (±2%FS),
(±3%FS), (±4%FS), (±10%FS), (±20%FS),
(±100%FS). It is set to ±4%FS by default.
Zero is allowed only when weight is within Manual-Zero range.
Zero-Tracking Range
Press to enter Zero-Tracking Range. shows.
Short press or press and to change range.
Zero-Tracking Range can be set to: (disabled), (±0.5e),
(±1.0e), (±1.5e), (±2.0e), (±2.5e), (±3.0e),
(±3.5e), (±4.0e), (±4.5e), (±5.0e). It is set to ±0.5e by default.
Enabling Zero-Tracking will enhance scale temperature and drift performance.
Zero Range
Press to enter Zero Range. shows.
Short press or press and to change range.
Zero Range can be set to: (disabled), (±0.5e),
(±1.0e), (±1.5e), (±2.0e), (±2.5e), (±3.0e),
(±3.5e), (±4.0e), (±4.5e), (±5.0e). It is set to ±5.0e by default.
Zero Range defines the range that scale must fall into before other operation becomes active. When load is removed from scale, left weight must be lighter than the value set.

Zero-Saving
Press to enter Zero-Saving.
shows.
Short press or press and to change
Zero-Saving status.
Zero-Saving can be set to: (enabled), (disabled). It is set to disabled by default.
When Zero-saving is enabled, Auto Zero is disabled automatically. Scale calculates weight based on the last Zeroing action.
Anti-Motion Level
Press to enter Anti-Motion Level. shows.
Short press or press and to change level.
Anti-Motion Level can be set to: (disabled), (weakest),
(weak), (normal), (strong), (strongest). It is set to weakest by default.
At the cost of measuring time, Anti-Motion intelligently settles down weight reading when scale is in motion. The weaker
Anti-Motion is, the faster weight reading displays, but the longer it takes to get stable weight reading.
Dynamic Weighing
Press to enter Dynamic Weighing.
shows.
Short press or press and to change
Dynamic Weighing status.
Dynamic Weighing can be set to: (enabled), (disabled).
It is set to disabled by default.
In some special application where scale ’s accuracy is not so important as scale
’s stability for weight reading and data printing,

Dynamic Weighing can be enabled to settle down the weight reading faster.
Gravity Acceleration
Press to enter Gravity Acceleration. shows.
Short press or press and to change digit.
Press and to right scroll digit. Press to input decimal point. Input Gravity Acceleration value.
Gravity Acceleration can be set from to: to .
It is set to 9.794 by default.
Adjust Gravity Acceleration, only when you use the scale in a place where acceleration of gravity is greatly different from the place where the scale is calibrated.
User Unit
Press to enter User Unit. shows.
Short press or press and to change digit.
Press and to right scroll digit. Press to input decimal point. Input User Unit value.
User Unit can be set from to: to .
It is set to
1.000 by default.
User Unit is a named unit which is usua lly used in user’s region, but not included in scale by default, like kg, lb, etc. It is a ratio to
System Unit. For example, if User Unit is set to 1.234 and
System Unit is kg, then after switching to User Unit, scale calculates weight (1000kg), and displays the calculated value
(1234usr).
