Unit conversion key->『lb/kg』
Short key → in weighing state, switch weight
unit. The corresponding unit
indication lamp is on.
Flicker bit is on the left.
Skin removal key->『Gross』
Short key → net weight turns to gross weight;
induction lamp of net weight “Net” is off.
Flicker bit is on the right.

VI Function Description
● ×10 function F2.1 = 0
How to operate
In normal weighing mode, press 『Total』 on the operation panel once,
the display accuracy will display 10 times and icon ×10 appears at the
same time; press the key again and it returns to normal weighing mode
and the icon of ×10 dissapears.
Note:
1. In net weight status, it’s forbidden to change over to ×10
function status;

12
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” will be highlighted on
indicator. 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.
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, you will be unable 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.

13
Target value acquisition
Hold 『Total』 until 【TARGET】 is displayed, and then press『Print』;
the present target value goes on and flashes.
If F2.6 = 0, press 『Print』, 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『Print』 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; load weight onto the
scale and press 『Total』 on the operation panel; if it displays
【 】, it means that the present weight has been counted in 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』 and 『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 get back to normal
weighing mode. If F4.2.1=1, pressing 『Print 』 can print the
accumulated data. To exit the interface, press 『Hold』.
● Counting Scale Function F2.1 = 5
Instrument display

14
【 】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.
● 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 lb; animal state indicator flashes. Press
『Print』 to print; press 『Hold』 or 『Total』 to quit the interface.
● VII Prompt Message of Instrument
The US-1011 indicator has extremely high stability and reliability, thus it is not easy
to have errors in a normal situation. However once an error does occur, first identify
what the error is and then make sure the idicator still has an error after turning off
and then turning on again before proceeding to troubleshoot. Repair the error
according to the error code as listed below:
