It can connect 4 pcs 350Ω Load cells at most with an M16-5 connector. As shown below

Power connection:

The indicator is powered by a 5V/1A adaptor, If you plug the adapter directly into the “DC” pin at the back cover the indicator is ok.

Communication interface:

Serial port RS232 uses the DB9 to connect to a big display, printer, or computer. As shown below:

Weighing Indicator Key’s Function

Weighing indicator display instructions

Operation:

• Press for 3 seconds to power on or power off.
• Kg/Lb Conversion: If you choose kg/lb conversion, in normal weighing mode, you can press a key to achieve kg/lb conversion.
• TARE/ZERO: When weighing exceeds the zero range（ ±2%） and is stable, press to enter into net weighing mode, display net weight zero, Tare and Net light on,
• Gross light off.
• When weighing in the zero range （ ±2%）and stable, press back to gross weighing mode, display gross weight zero, Gross light on, Tare, and Net light off.
• Preset tare.
• Press “Tare” for 2 seconds and enter the Tare weight to the Tare function.

Hold Functions

• This indicator includes peak hold, hold, auto-hold, animal function, and trails of animal function.
• C11=0 no hold function
• C11=1 Peak hold C11=2 Data hold
• C11=3 Auto-hold
• C11=4 Animal function
• C11=5 Trails of animal function
• C11=6 Stable hold function
• Peak-hold: Press the HOLD key, then the Hold light is on, and show the maximum data on the weighing indicator. Press the HOLD key again to exit the hold function
• Hold: Press the HOLD weighing indicator. Press the HOLD key, then the Hold light is on and show the data on the key again to exit the hold function.
• Auto-hold: If the weight on the scale is above 20d and keeps stable, the indicator will show the data for 6 seconds and the (HOLD) light is on, after 6 seconds the indicator back to general weighing, and the HOLD light is off.
• Animal function: Press the HOLD key, and the indicator will show “LOC” for 5 seconds, average the collected weight, and show the calculated animal weight the (light is on.
• Press the HOLD key again to exit it. The HOLD light is off.
• Trails of animal function: In the trails, animals are automatically weighed with the front legs placed on the scale. The duration of the animal weighing process can be configured using C40.
• Once the animal’s weight has been determined, the indicator will briefly display “LOC” for 5 seconds.
• During this time, the collected weights are averaged to calculate the animal’s weight. After the animal steps off the scale, the indicator returns to its standard weighing mode, and the “Hold” light turns off.
• Stable hold function: Once the animal is on the scale, it will automatically stabilize, and the indicator will calculate the weight of the animal.
• This automatic animal weighing function, when compared to the trial of animal function, doesn’t require any manual triggering and offers a quicker response.
• It also can support the weighing of multiple animals on the scale simultaneously.
• However, it is important to note that this function may not be suitable for very active animals.
• To use this function effectively, it is necessary to configure the parameters C28 and C29 for digital filtering.

TOTAL

• Accumulation operation: At Zero mode, load weight till stable, press the TOTAL key to go to accumulating mode, TOTAL light on, display “n001”, and then display loaded weight; unload weight, back to zero, load weight again till stable, press
  then show the loaded weight. Repeat it a maximum of 999 times. TOTAL display “nO02”,

• Check the total weight operation: Press PRINT hold it then press TOTAL at the same time, display “n (accumulating times) then display total weight. If the total weight does not exceed 6 digits, it is displayed as 6 data total, otherwise, the total weight is 8 data total, and it shows the first 4 digits, then the last 4 digits. For example, the first 4 digits are 0012 the last 4 digits are “34.56”, which means the actual weight is “1234.56

• Exit accumulate function: At TOTAL (accumulate) mode, press a TOTAL key the indicator shows cir n which means don’t clear the total weight, press the key to confirm it and exit;

• If clear the total weight is when displaying “cir n”, press TARE ZERO to change it to “cir y” It means a clear total weight display. Press mode. PRINT to clear the total weight and exit accumulating

Ten times higher resolutions

Press the PRINT and TARE ZERO keys at the same time, and you will get 10 times higher resolutions. And it will back to normal weighing after 3 seconds

Up and Under limit alarm

Please. set C13= Up limit, C14=Under limit, when the weight is over the up limit, the “Hi” light will on, and the indicator will make a sound to alarm
When the weightis below than the low limit, the “Lo” light will be on. When the weight is within the limit, the “OK” light is on

Print

When the data is stable, the connection to the printer will be printed after pressing PRINT 1 second.

Calibration and Parameter Settings

Maintenance

Regular Error and maintain method:

Daily maintenance

To ensure a clear display on the indicator and extend its lifespan, please observe the following guidelines.

1. Avoid placing the indicator directly in sunlight.
2. Ensure a proper connection between the load cell and the indicator. The system should have a robust ground and be kept away from strong electric or magnetic fields.
3. Refrain from using the indicator outdoors in rainy conditions, and it is recommended to keep it powered off in such situations.

Battery

• In the lower right corner of the indicator, there’s a visible battery voltage display.
• If the battery voltage becomes too low, the last grid will begin to blink, indicating that it’s time to recharge.
• During the charging process, the battery grid will flicker, and typically, it takes around 6-8 hours to fully charge.
• Once the battery is fully charged, all the power grid lights will illuminate.
• It’s worth noting that the indicator features a built-in intelligent charge management chip, which allows it to continue using the power supply after reaching a full charge, preventing overcharging of the battery.

Restore default parameters

• Enter the setting menu, set C07= 1, press PRINT then press exit saving setting, all parameters will be back to the default setting
• Note: Please avoid restoring default parameters if you lack professional knowledge and do not have experience with scale calibration.

Default parameter form

NOTE: means this option is only for NTEP version
