Function Description
● ×10 function F2.1 = 0
Operation
In normal weighing mode, press 『Total』 on the operation panel once,
the display accuracy will promote for 10 times and icon ×10 gets on at
the same time; press the key again it returns to normal weighing mode
and the icon of ×10 gets off.
Note: 1. In net weight status, it’s forbidden to change over to ×10 function status;
2. If there have been 4 decimal places, it’s forbidden to change over to ×10 function
status;
3. Under ×10 function status, both serial output and printing output are forbidden.
4. Under ×10 function status, it’s forbidden to tare.
● Weight hold function F2.1 = 1
How to operate In normal weighing mode, press 『Hold』 on the operation
panel once, the weight presently displayed can be locked and “Hold”
indicator gets. Weight Hold operation is valid only when the displayed
weight is ≥F2.2 set value; otherwise, it displays invalid operation with
【 】 for one second and the scale goes back to normal weighing
mode.

13
If the weight is locked, press 『Hold』 again to unlock and it goes back to
normal weighing mode and “Hold” indicator goes off.
In weight locked status, it refuses to tare, clear tare and zero.
● Percentage display F2.1 = 2
Display introduction
Displaying 【 】 indicates 20.5 %.
Pr = present actual weight / measuring range ×100%
Pressing 『Hold』 key to change over between percentage and weight
● Weight check, sorting scale function F2.1 = 3
Function description:
Parameters as F2.2 = A, F2.3 = B, F2.4 = C, F2.5 = D etc shall be set.
Presently displayed weight is X.
If X ≤ A, no weight check or sorting will be performed.
If X ＜ (B – D), it stands for short weight; the short-weight icon goes
on.
If (B – D) ≤ X ≤ (B – C), it stands for PASS; PASS icon goes on.
If X ＞ (B – C). It stands for overweight; overweight icon goes on.
Target value acquisition
Hold 『Total』 until 【TARGET】 is displayed, and then press『ON/OFF』;
the present target value goes on and flashes.
If F2.6 = 0, press 『ON/OFF, the present weight on the scale will be taken as
new target value and it exits setting interface.
If F2.6 = 1, it displays 【 】, requiring modifying the target value
manually. After the modification, press『ON/OFF』 to save the data and exit
the setting interface.
Press 『Hold』 to exit target value acquisition.
● Accumulating scale function F2.1 = 4
How to operate
In normal weighing state, the scale is at zero; apply the scale with
load and press 『Total』 on the operation panel; if it displays
【 】, it means that the present weight has been counted in

14
the accumulated value; then it goes back to normal weighing status.
If it displays 【 】 for one second and then goes back to normal
weighing mode, it means invalid operation! Causes: 1. The scale must
be zeroed between two successive accumulation operations,
otherwise, accumulation will be refused. 2. Accumulation is valid
only when the displayed weight is ≥F2.2 setting. 3. The scale is in
dynamic status.
Adjusted display, clearing, and printing of accumulated value
In normal weighing mode, hold 『Total』 on the operation panel for
over two seconds, it displays 【 】 for one second; then the
monitor shows the present accumulated value 【 】 or times
of accumulation 【 】; press『Gross』,『Ib/kg』to change over;。
now the adjustment display icon goes on. Now if it’s necessary to
clear the accumulated value, press 『Zero』 to have the display
becomes into “0”. If F4.2.1=1, pressing 『Print』 can print the
accumulated data. To exit the interface, press 『Hold』.
Note: whether to be over the specific data and accumulated data can
be set in F4.6.
● Counting scale function F2.1 = 5
Instrument display
【 】，displays the present counts
Sampling method
1. Check whether the scale is at Zero, otherwise, press 『Zero』.
2. Put the counted material onto the scale platform.
3. Hold 『Total』 until 【 】 is displayed; then press『Print』.
If F2.6 = 0, it displays【 】. Enter the value just counted and then
press 『Print』 to confirm, the sampled data will be saved and the
system exits sampling interface. If F2.6 = 1, it displays【 】; enter
the sample weight and press 『Print』; the system saves the setting
data and exits sampling setting interface.
4. In this function, press『Hold』 to switch between counts and weight.

15
● Animal scale functions F2.1 = 6
Operation method
In normal weighing state, place the animal on the weighing platform and its
weight must be ≥threshold value set in F2.2. Press 『Total』, instrument will
collect data sampling. After sampling, the average value of sampling data
will be locked, showing X.XXX kg; animal state indicator flashes. Press『Print』
to print; press 『Hold』 or 『Total』 to quit the interface.

Prompt Message of Instrument
The instrument has extremely high stability and reliability, thus is not easy to
have error in general situation. Once an error occurs, please make clear the error
first and observe whether the instrument still has error after power-on. Do not
hurry to repair the scale body or instrument. Repair the instrument according to
error code of the instrument as possible
