Instructions for Use and Description

Tare

To tare, place the load to be weighed on the scale platform, wait for the stability indicator to light up, then press the tare key. The display will show zero and the net weight indicator light will illuminate. Remove the load and press the tare key again to cancel the tare, and the net weight indicator light will go out.

Zero

To zero the scale, wait for the stability indicator to light up and then press the zero button. The zero indicator light will illuminate while the scale is zeroed. The scale will perform an automatic zeroing each time it is switched on. The automatic zeroing device at start-up operates in a range of +-10% of the maximum capacity.

Weighing Function of Animals

To use the animal weighing function, set the value [P 9] to [2]. To deactivate the animal weighing function, set the value [P 9] to In the parameterization, set the value In the parameterization, set the value [P[P 9] 9] to to [2][2] to start the animal weighing function. to start the animal weighing function. Set the value [P[P 9] 9] to to [1][1] to deactivate the animal weighing function. to deactivate the animal weighing function.

Accumulation Function

The accumulation function is not described in the manual. In weighing mode, pressing 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 to normal weighing mode and the ACCUM light will turn off; 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 will turn off.
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.

Piece-counting function

In weighing mode press and hold In weighing mode press and hold to enter the count function. to enter the count function. The count light willThe count light will come on and the display comes on and display [Count][Count]. When stable, press the . When stable, press the key to enter the sample number setting and number set, and [C00000][C00000] will be displayed. will be displayed. After placing a few samples, press after placing a few samples, press the key to change. Press the key to change. Press the key to set the value of sample numbers. key to set the value of sample numbers. After setting the value of the current sample number, press, press to sample and to sample, and [——][——] will be displayed. When a number appears you can start counting. displayed. When a number appears you can start counting. This sampling date will beThis sampling date will be saved. Press the key saved. Press the key to exit the counting mode. to exit the counting mode.

Note: If the sample weight is less than the minimum sampling weight, the sampling will note: If the sample weight is less than the minimum sampling weight, the sampling will fail and the data from the previous sampling will be taken. If the weight of the sampling fails and the data from the previous sampling will be taken. If the weight of the sampling unit is less than the minimum weight of the sampling unit, the sampling will also fail unit is less than the minimum weight of the sampling unit, the sampling will also fail and the data from the previous sampling will be taken. and the data from the previous sampling will be taken.

Upper and Lower Limit Alarm Settings

The upper and lower limit alarm settings are not described in the manual.

System Setup configuration

In weighing mode, press and hold the user setting key to enter the user setting mode. Press the key to change the value. Press the key to enter the next parameter; when all parameter settings have been completed, press the key to exit the user configuration mode.

Communication Protocol Instruction

The communication speed of the indicator and the communication method can be set and selected in system configuration. The default baud rate is 9600 and the communication mode is the continuous transmission. P10=1:
Data format: = . All data are ASCII code Includes data format with 6 digit weight and bit signal. All lower position weight data are in front. High position and sign bit. the negative number sign bit will send [-]. the positive number sign bit will send [0]. For example, when the indicator shows [-500.00kg], the serial output data is [=00.005-]. When the indicator shows [500.00kg], the serial output data is [00.0050].

P10=2:
The indicator sends 13 characters as in the following list:

• 1-2: WN
• 3-9: Weight including decimal point
• 10: 0x20
• 11: unit kg
• 12-13: 0x0d 0x0a

P10=3:
The indicator will output gross weight, net weight, tare weight and serial number. It can be used to connect a small ticket printer.

Failure and correction

Use of Battery

The use of battery is not described in the manual.

• The battery charging is done while the indicator is connected to a 220Vac socket.
• The voltage indicator flashes 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 first use the battery charging time is longer than 24h to ensure that the battery meets safe and stable working conditions.
• t 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 first time, make sure that the battery is fully charged.

Maintenance and Precautions

Maintenance and precautions are not described in the manual.

• In order to extend the life of the weight indicator it should not be installed in direct sunlight.
• Avoid installing the scale in humid environments and keep it isolated from severe vibrations.
• Do not use strong solvents such as benzene and nitro-based oils to clean the housing.
• Avoid spraying liquid on the indicator to prevent damage and electric shock.
• The battery incorporated in the electronic scale is consumable and is not covered by the warranty.

Calibration Instructions

Calibration instructions are not described in the manual. In the of the off state, press and hold if state, press and hold to open the display, until the weight w, until the weight window shows [d X][d X] release the key to enter the calibration procedure. release the key to enter the calibration procedure. The calibration procedure is as follows:

Press to set the division value.

Press to enter the decimal point setting menu. Press to set the decimal point to the desired location.

Press the key to enter the Max Capacity setting. Press the to change digit, press the key to change the value.

Press to access the zero setting option.

Press to access calibration with a known weight.

Press the key to complete the setting.

Open the cable sealing device on the back of the indicator. Unscrew the M5 screw with a screwdriver. The calibration switch is located under the M5 screw.

Put the M5 screw back into position. Then unscrew the M4 screw with a screwdriver- Place the M4 screw into the port of the calibration switch. Briefly depress the M4 screw. The indicator will save the calibration data and return to the weighing state. Replace the M4 screw in the corresponding position with a screwdriver and seal the cable to finish the process.
