Remark
～
Dynamic and static
indication
The lamp is on when scale is in dynamic
state, otherwise, the lamp is off
Zero center indication
The lamp is on when the absolute value of
weight on the scale is less than ±0.2d,
otherwise the lamp is off
Net
Identification of gorses
weight and net weight
The lamp is on in net weight and off in
gross weight
lb
Weight unit

kg
Hold
Weight maintenance
The lamp is on when the weight is locked,
otherwise it is off

Ac
Voltage indication of
battery and power supply
The green lamp is on when the voltage of
the adapter and battery is normal, and the
red lamp is on in undervoltage state
●Introduction to operation keys
Operation without special specification refers to short press on keys.

Weight maintenance key
Short press→ F2.1 = 1, keep/cancel.
F2.1 = 2, switch between percentage
and weight.
F2.1 = 5, switch between quantity
and weight.

Accumulation key
Short key → F2.1 = 4, include display weight
in accumulation value.。
Long key → F2.1 = 3, select scale to sample
target weight.
F2.1 = 4, accumulate weight of scale
display.
F2.1 = 5, count sampling of scale.
No definition.
Unit conversion key
Short key → in weighing state, switch weight
unit. The corresponding unit
indication lamp is on.
Flicker bit is on the

Skin removal key
Short key → net weight turns to gross weight;
induction lamp of net weight “Net” is off.
Flicker bit is on the
right.
Skin removal key
Short key →gross weight turns to net weight.
Indication lamp of net weight “Net” is on.
Conduct skin removal operation for multiple
times.
Digit flicker
position reduces.

Zero clearing key
Gross weight state resets weight. When the
scale is in net weight, dynamic state, saving
state and out of resetting range, zero clearing
operation is invalid.
In setting, digit of
flicker position
increases. In
adjustment of
display,
accumulation is
cleared.
Printing key
Short key → start up or print.
Printing format refers to Appendix1.
Long key → shut down.
Confirm operation,
to save setting
data.
V. Parameter Setting
Setting entry:
Press the [Hold] button on the operating panel in the state of normal
weighing.
If F1.14 = 0, you can set all the parameters within F1~F5.
If F1.14 = 1, you can only set all parameters within F2~F5.
If F1.14 = 1 and you need to set the parameters within F1 menu, you
can press the calibration switch button until the F1 menu is entered.
Parameter Setting of F1 Scale
F1.1 Measuring Range
Selectable parameters: 3~200000 (default value: 6)
F1.2 Decimal Places
Selectable parameters: 0 ---- no decimal point
0.0 ---- 1 decimal place
0.00 ---- 2 decimal places
0.000 ---- 3 decimal places (default
value)
0.0000 ---- 4 decimal places
F1.3 Number of Divisions
Selectable parameters: 1 (default value), 2, 5, 10, 20,
7
50

F1.6 Null-point Calibration
【 】 Keeping empty the scale
Remove the weights on the weighing platform to
guarantee the scale is in the empty state. Press the
[Print] key and the meter will display [ ].
The displayed digits will reduce slowly until the
meter displays [ ]. In the end it will display
[ ] for one second, which indicates the end
of null-point calibration.
F1.7 Load-point Calibration
【 】 Loading weights
Load weights on the weighing platform to ensure
that 10% of full-scale value ≤ weight of weights
≤ full-scale value, and then press the [Print] key
to start the next step.
【 】 Entering the same weight value as that of the loaded
weights.
Entering the same weight value as that of the loaded
weights, please press the [Print] key after the scale
becomes stable, and the meter will display [ ].
After that, the displayed digits will reduce slowly until
the meter displays [ ]. In the end it will display
[ ] for one second, which indicates the end of null-
point calibration.
