Key Function
Press this key to turn the display on/off.
Press and hold this button for more than 5 seconds in weighing mode,
you will enter user parameter setting mode; press and hold this button for
less than 5 seconds, you will enter a ales weighing mode.
In weighing mode, press this button to accumulate the weight; in self-test
mode, press and hold this button to enter calibration mode; in calibration
process, press this button to change the parameter setting.
In weighing mode, press this button to tare; in parameter setting mode,
press this button to change the parameter value.
In weighing mode, press this button to zero; in calibration process, press
this button to change the value.

4.1. Tare
Place the load to be weighed on the scale platform, when the stability indicator lights
up, press the key to tare. The display shows zero and the net weight indicator light
comes on. Remove the load and press again the key to cancel the tare, the net
weight indicator light will disappear.
4.2. Zero
Zeroing of the scale. The stability indicator must be lit. While the scale is zeroed, the
zero indicator lights up.
4.3. Animal weighing function
In the parameterisation, set the value [P 14] to [2] to start the animal weighing function.
Set the value [P 14] to [1] to deactivate the animal weighing function. The [P 13] function
is the ltering force. In weighing mode, press and [--CT--] will be displayed, after
a few seconds the scale will lock the current weight automatically; press the If the
scale is reset or zeroed, the scale can go into normal weighing mode.
4.4. Accumulation function
In the weighing mode, press the key the indicator will accumulate all the current
weight, and at the same time the ACCUM indicator will light up. Press the key
again, it will go into normal weighing mode and the ACCUM light will go out; press the
key with the counter at zero, to display the current accumulated value; under the
accumulation status, press to reset to zero, press can return to normal weighing
mode and, at the same time, the ACCUM lights go out.
Note: the balance must be zeroed before the next accumulation operation. otherwise,
you will not be able to perform the accumulation operation a second time.
4.5. Upper and lower limit alarm settings
Press and hold down the key to enter the upper and lower limit function setting.
[Set_H] is the upper limit setting, press the key to change, press the key to x.
Press the key to enter the lower limit setting. [Set_L] will be displayed, then you
can press the key to exit the setting. The upper and lower limit alarm is indicated by
the indicator and the alarm buzzer sounding at the same time. You can select the alarm
mode through the system setting P4.
Note: The upper limit value must be greater than the lower limit. If the set upper limit is
less than or equal to the lower limit, the indicator shall not alarm.

5. System setup
In the weighing mode, press and hold down the key to enter the user conguration mode.
Press the key to change the value. Press the key to enter the next parameter; when
all parameters have been set, press the key to exit the user conguration mode.

6. Failure and correction
Display Instructions
Err1 The AD value is too small when calibrated or the load cell capacity is
too large.
Err2 Zero point is out of range when calibrating.
Err3 The zero point is out of range at start-up or there is too much weight
on the scale.
Err5 No load is detected when calibrating the scale.
Err7 Incorrect load cell signal, check the wiring.
Err8 The load cell signal is not stable.
7. Use of battery
• The battery charging is done while the indicator is connected to a 220Vac socket.
• The voltage indicator ashes to indicate low battery, please connect the power cable to
charge the device.
• When the electronic scale displays the message LOB (“low battery”) the weighing
function will stop. Please immediately switch off the equipment and plug it into a 220Vac
socket to recharge the battery.
• It is recommended that before the rst use the battery charging time is longer than 24h to
ensure that the battery meets safe and stable working conditions.
• It is recommended to charge immediately when the battery is low as failure to do so
may damage the battery and shorten its life. It is recommended that the charging time is
longer than 12h. If the battery is not used for a long time, it should be recharged every
two months for about 20-24 hours to protect the battery from damage and prolong the life
of the battery.
Caution: The battery cable must not be reversed (red +, black -), otherwise the
device may burn out. When using the device for the rst time, make sure that the
battery is fully charged.
