Unpacking
After unpacking, please check the contents to ensure all of the components are present and there is no damage. If parts are missing or damaged, please contact customer support.

NOTE: Batteries and Data Cable Are Not Included

Installation

1. Assemble the scale by installing the pan holder and weighing pan.
2. Attach the power cord and plug the scale into a 110V/220V socket.
3. Please confirm the correct voltage before using the scale.

Getting Started

1. Ensure the scale is level. The supports on the bottom of the scale can be screwed in or out as needed to level the instrument.
2. Press the ON/OFF button to turn the scale on. The scale will count down from 999999 while the unit updates.

Calibration
NOTE : The counting scale is calibrated at the factory and can be used out of the box. It should be calibrated one time per year.
The calibration function can auto-detect any calibration weight in multiples of 100g, i.e., 200g, 500g, 1000g, etc., as long as the weight does not exceed the maximum capacity of the balance. Use a calibration weight of at least 20% of the total capacity of the scale (eg. 6kg for a 30kg capacity counting scale.

1. Quickly press ZERO three times. “AU-CAL” will be displayed on the lower right corner of the screen.
2. Place no less than 20% of the full range of weights on the weighing pan. The instrument will be calibrated.
3. Calibrate the instrument using any available reference weights.
4. The instrument can only be as accurate as the standard masses used.

Zero
Short press the ZERO button before weighing to ensure an accurate reading, (starting from 0).

Unit Conversion
Press and hold the MC button for 3 seconds to switch between the available units of measurement, (g, kg, oz, lb).

Tare

1. Place an empty container on the pan. Its weight will be displayed. Press TARE until “0” is displayed.
2. Place additional objects in the container to find the net weight.
3. When you remove the empty container, the scale will display a negative number.
4. Press TARE again and the weight display will return to “0.”
   Press TARE before weighing to ensure accurate reading (starting from 0). Counting Function

NOTE: Use larger initial samples for more accurate results:

• Pcs. Weight <0.3g = Not Accurate.
• Pcs. Weight 0.3g -0.5g = Use 50+ pcs sample for counting function.
• Pcs. Weight: >0.5g = Use 10+ pcs sample for counting function.

PCS/SET

• This counting function is used to count the number of parts by extrapolating values from the original sample.
• Place the sample on the scale.
• Input the number of pieces in the sample by using the numerical keys (use at least 10pcs). Press PCS/SET to confirm.
• As more units are added, the counting window will show the amount of units. The total weight window will display the total sample weight.
• The unit weight window will display the weight of a single unit.

WT/SET

• Enter the unit weight with the number keys and press WT/SET.
• When more units are added, the counting window will show the total number of pieces.
• The total weight window will display the total sample weight.
• The unit weight window will display the weight of a single unit.
• Press CE to cancel the WT/SET setting.

Accumulation Function

1. Use M+ to find the cumulative weight and piece count of samples. For example, place a sample of 100 pcs (2kg) on the scale. Press M+ and remove the sample. Add 50 pcs (1kg), weigh, and remove. Press M+ and the total count (150 pcs) and weight (3kg) will be displayed.
2. Place the first sample on the weighing pan.
3. Once the weight is shown, press M+.
4. Remove the first sample from the weighing pan. The display will return to “0.” Place the second sample on the weighing pan.
5. Press M+ again.
6. Remove the second sample from the pan. The display will return to “0.” Repeat this step for each sample.
7. Once all samples have been weighed and removed, press M+ and the entire weight and count will be displayed.
8. Press MC to clear all data.

Checkweighing/Alarm

• The Checkweighing/Alarm function is used to signal upper and lower limits for count and weight.
• Press Alarm.
• The screen will display 0.0kg in the top box and L in-hi in the lower.

NOTE: The scale displays ‘kg” each time. The alarm is however for whichever unit was last used. For example, if you had been using grams before pressing Alarm, the check weighing mode is for grams (even though it shows kg.

• If you would like to set upper and lower boundaries for pieces, rather than weight, press ZERO to toggle between the settings.
• Enter the upper bound for weight and press Alarm to confirm.
• The scale will display L in Lo.
• Enter the upper bound for weight and press Alarm to confirm.
• If you place something on the scale outside of the range it will flash either LO or HI.
• To cancel the alarm, go back through the settings and press CE for both the upper and lower bounds.

LP50 Print Mode Settings

• Hold “.”
• The screen will display InPAGE no. XXX.
• No. XXX will correspond to the pre-existing printer format. Use number keys to choose pages to print.
• Use CE to redo input.

RS232 Printout Settings
Connecting the balance to a PC requires an RS232 to USB adapter serial cable (not included) and COMToo[BE1] l. COMTool is a serial communication terminal program that can transmit bytes to and from devices connected to the PC’s COM port.

Using COMTool

• Connect the balance to the PC using the RS232 cable. Open COMTool and select the COM port.
• Set the baud rate to 9600.
• Select serial input R.
• Short press the CAL/PCS button to send data to the PC.

Adjusting the Baud Rate
The baud rate is the rate of data transfer to the PC. It indicates how many bits per second can be transferred. The default baud rate for the balance is 9600. The baud rate settings for the balance and receiving PC must match.

To adjust the baud rate:

• Press 7, 8, and 9 using the number keypad.
• The display will cycle, and then show “diu”.
• Press PCS/SET until the display shows “bud”.
• If “9600” is not displayed, press PCS/SET until it is. Press the Alarm to confirm.
• Turn off and then turn on the scale.

Cleaning

• Always power off and unplug the scale before cleaning or storing it.
• Use a damp cloth to wipe down the scale and weighing pan. For stubborn stains, use a mild detergent on a damp cloth. Dry the scale after cleaning. Do not clean the scale with solvents or cleaners that may cause damage or corrosion.
• Do not immerse the scale in water or other liquids.
• Do not use a stream of water to clean the scale.
• To avoid injury, use proper safety equipment (e.g., gloves, eyewear, etc.) when cleaning the scale.

Troubleshooting

If these troubleshooting measures do not solve the problem, contact customer support. The balance should be serviced by authorized technicians only.

Factory Testing
Your balance has undergone extensive quality control (QC) testing at the laboratory before shipment. The following QC tests have been conducted:

Margin of Error
Testing is performed to verify that the margin of error is less than .03g for a .01g
balance.

Linearity
This testing is conducted with 4 different weights measured 4 times. For example, for a 1000g maximum-capacity balance, linearity testing will be conducted with weights of 200g, 500g, 800g, and 1000g. Larger capacity scales are tested with more weights and more repetitions of testing. Testing is conducted until the readings are consistent and accurate.

Repeatability
A weight representing the maximum capacity of the balance is weighed 10 times until the margin of error for each weighing is less than the acceptable specified margin of error, i.e., less than .03g for a .01g accuracy balance. As an example, for a 2000g maximum capacity balance, a 2000g weight is used. To pass the repeatability test, each reading must fall within 1999.97g and 2000.03g.

Four Points Testing
Four-point testing is conducted by placing a weight on each corner of the pan consecutively (not at the same time) and taking a reading each time. Each reading should fall within the accepted margin of error to pass the test.
