I. Precautions before use
Please read this instruction manual carefully
before you use this scale.
1. Rain or washing with water is strictly prohibited.
2. Electronic scales are strictly forbidden to be placed
in hot or humid places.
3. Do not allow cockroaches and small creatures to
enter the machine and cause damage.
4. Do not hit or press (do not exceed its maximum
weight capacity).
5. Remove the battery when it is not in use for a long
time.
6. When it is found that it can’t be used for a long time
after charging for more than 10 hours, it means that
the battery has aged. Please contact the factory for
replacement.
II. Preparation before use
1. Please use the electronic scale on a stable, flat table;
do not place it on a rocking or vibrating gantry. Use
four adjustment feet to keep the machine steady, and
note that the bubble of the level needs to be in the
center of the circle.
2. Avoid using the electronic scale in places where the
temperature changes too much or the air flow is severe,
such as direct sunlight and the air outlet of the air
conditioner.
3. Please use a separate power outlet to avoid

interference from other appliances.
4. Do not put anything on the scale when you turn on
the power.
5. It is best to heat the machine for 15-20 minutes
before using the electronic scale to ensure
accuracy.
6. The use environmental temperature of electronic
scale: 0 ℃ ~ 40 ℃

V. Function operation
1. Boot
Remove the object on the scale plate, move it to the power
switch, the electronic balance (scale) will display
self-inspection, and then return to zero and enter the weighing
state
2. Shutdown
Turn the power switch again to shut down.
3. Zero
If there is no object on the scale, but it shows weight on the
display when using the scale，press to make it zero.
The weight value of the item is within the range of zero. If the
weight value exceeds the range of return to zero (±10%·FS)
and in the condition of peeling, press does not work.
4. Function operation
1：Cumulative operation
Cumulative: scale to zero, put the object on, and
wait for the data to stabilize, press once，shows
“Add xx”. After 2s, the scale returns back to weight,
if continue to cumulative, then must remove the object,
waiting for weight, put the object on again, waiting for
the data to stabilize, press again, and so on.
2. Cumulative indications: in the state of weighing
zero, long press the key, the single window
displays the accumulated number of bills, the weight
window displays the total weight accumulated, and the
quantity window displays the accumulated quantity.
Press the key to return to the weighing state.
3：Upper and lower limit setting
Lower limit value setting: in the state of returning
to zero, press the key longer than 3s, enter the
lower limit value set, the weight window shows "dn"
and " 0.0" flickering back and forth, press and
to enter the lower limit value you want to set,
press the key to determine.

Upper limit value setting: in the state of returning
to zero,press the key more than 3s, enter the
lower limit value setting，display "UP" and "0.0" back
and forth, press and to enter the lower
limit value you want to set, press the key to
determine.
Quickly set limits：Put items on scale and
long press or more than 3s,
It sets the upper and lower limits for the
number you weigh.
1>If the lower limit is 0 and the upper limit is not
0, it represents: when the weighing data is greater than
the upper limit value, an alarm is issued.
2>If only the lower limit value is not 0, the upper
limit value is 0, which means: When the weighing
data is less than the lower limit value, it will alarm.
3>If only the lower limit value is not 0, the upper
limit value is not 0, and the lower limit value is less
than the upper limit value, which means: when the
weighing data is less than the lower limit value, or
greater than the upper limit value, the alarm is issued.
4>If only the lower limit value is not 0, the upper
limit value is not 0, and the lower limit value is greater
than the upper limit value, which means: when the
weighing data is greater than the lower limit value, or
less than the upper limit value, the alarm is issued.
4. Counting operation
If you need do testing for the members of sample，when it
shows zero，press more than 3s, it
shows PC 20, means sample have 20 pcs，press
to choose sample quantity, 20，40，60，80，100，
Put same members of goods on the scale，press
confirm. Press again to back to counting state.
5．Tare
If packaging is required to weigh the item, follow these
steps: pack the object placed on the scale, press to
deduct the weight of the package. The weight value is displayed
as zero，The display shows“ ”。，then put the goods on

the scale that you want to weight，that’s the net weight。It will
shows negative number when you take the goods away。The
tare Model will be shows again when you press again.
6. Charging instructions
When the battery power is low, please charge for 12 hours
before using. When charging, the charging indicator
shows “red” and when full it shows “green”. Continue charging
for 3-4 hours to ensure sufficient battery power.
