4) Enter/Cancel animal weighing function when “F3 KEY”=5;
UNIT Key
1) When self-checking, press UNIT Key to set unit conversion coefficient.
2) Unit conversion when weighing.
SECTION 3 OPERATIONS
3.1 Power on/off
Press ON/OFF Key to power on the Indicator and the indicator self-checks, then goes into the weighing state.
3.2 Functions and parameters setting
When self-checking, press ZERO Key to enter parameter setting. Then display shows “F1 CLK”. Press TARE
Key to move functions cycle. Press FUN Key to enter the desire function or MOD Key to cancel or quite. See
details on Section 4 Functions and Parameter Sections.
When self-checking, press TARE Key to enter “P8 CAL”calibration function.
When self-checking, press MOD Key to enter “P13 UT”unit setting.
When self-checking, press FUN Key to stop self-checking and it goes into the work state.
When self-checking, press UNIT Key to enter unit conversion coefficient setting.
3.3 Zero the scale
Press ZERO Key to set the zero point from which all other weighing and counting is measured. Usually this will
only be necessary when the platform is empty. When the zero point is obtained the ZERO indicator is ON.
The scale has an automatic re-zeroing function to account for minor drifting or accumulation of material on the
platform. However you may need to press ZERO Key to re-zero the scale if small amounts of weight are shown
when the platform is empty.
3.4 Tare the scale
When a container is applied it needs to tare off and obtains a net weight. Remove all weights from the platform
and make the platform empty. Make sure that the ZERO indicator is on. Place a container on the platform and the
container’s weight will be displayed. Press TARE Key to tare the scale. The container’s weight will be stored as a
tare value and the value will be subtracted from the display, leaving a zero value on the display. The TARE

--

indicator will be on to show the indicator is now under tare operation. A product is placed in the container and it
will show only the weight of the added product. The scale should be tare a second time if another is added to the
first one.Again only the weight added after tare will be displayed.
When the container is removed a negative value will be shown. If the scale was tare just before removing the
container this value is the gross weight of the container plus all products that were removed. The ZERO indicator
will also be on because the platform is back to the same condition it was when the ZERO Key was last pressed.
To clear the tare value, empty the platform and press TARE Key again, TARE indicator will be goes off.
3.5 Parts counting (KEY=1)
Tare the weight of any container that is used, leaving the empty container on the scale. Place samples on the
scale. The number of samples should match the options for parts counting, 10, 20, 50, 100 or 200 pieces.
Weighing sample: Press MOD Key to begin the parts counting. The scale shows "P 10" asking for a sample
size of 10 parts. Change the sample size by pressing the TARE Key, the display will cycle through the options:
10/20/50/100/200.
Counting: Press FUN Key when the number matches the sample size. Remove samples from the container
and place the desire parts for counting purpose. Display will show the number of parts (pcs).
Viewing the Unit Weight, Nos. of Counts & Total Weight:
Press FUN Key to cycle through Unit Weight, Nos. of Counts and Total Weight. (Note that the Unit Weight will
show in gram.)
Press MOD Key to return to normal weighing.
3.6 Accumulation (KEY=2)
Accumulate the weight:
When weighing, press FUN Key for accumulation.
Place the products that to be weighed, when the STABLE indicator is on, press MOD Key and the weight value
will be stored in the memory. The display will show nos. of accumulation. After that it goes to normal weight
display. Do other subsequent weighing by the similar procedure as described above. Note: This Indicator can
store 200 Nos. of accumulation.
View the accumulated total weight:
Empty the scale by removing the weights. Press FUN Key it will display the Nos. of weights, and then total
weight.
Clear the accumulated weight from memory:
Press ZERO Key during display of the nos. of weights and total weight, accumulated weights are cleared from
memory.

3.7 Holding the weight (KEY=3)
Press MOD Key to enter the hold function. After every weighing, the weight value will be kept on the display.
MOD Key can be pressed to cancel hold function.
3.8 Presetting tare value (KEY=4)
Press MOD Key to preset tare value. While every weighing, the value displayed is the one actual weight
substrate the preset tare value.
3.9 Animal weighing (Key=5)
Press MOD Key to set parameters of animal weighing.
1) Stable time “Fil n”. Options: 1/2/3/4/5. 1 is the fastest and 5 is lowest. The longer of stable time, the harder to
lock.
2) Display range “Rang n”. Options: 1/2/3. Option 2 is recommended.
3) Leaving lock range. If the change of weight exceeds the value, the indicator will get a new display.
Press FUN Key to enter or cancel the animal weighing function.
3.10 Check-Weighing
Check-weighing is a procedure to cause alarm to sound when the weight on the scale meets or exceeds values
stored in memory. The memory holds values for a high limit and a low limit.
Check range:
Set hi-limit and low-limit as different values, and hi-limit value is larger than low-limit value.
Check key point:
Set hi-limit and low-limit as same value.
Check mode:
Setting the parameter: Select ”F4 CHK”to enter check mode. Press FUN Key to enter and sub select “BEEP 1,
BEEP 2 or BEEP 3”; Press FUN Key, it will show “XXXXXX”. Then begin to set high-limit value; Press Enter to
set low-limit value;
Mode 1: BEEP=1, never beep whether it is eligible or not, but the indicator HI or LO will be on or off to show the
result. When the weight is higher than the high-limit, indicator HI will be on, while lower than the
low-limit indicator LO will be on. Otherwise indicator HI & LO will be both on.
Mode 2: BEEP=2, beep when it is eligible;
Mode 3: BEEP=3, beep when it is not eligible.
Note: The weight must be greater than 9 scale divisions for the check weighing to operate. To disable the
check-weighing function press UNIT Key to set both high and low limit to zero.
