all operating and safety instructions.
Safety Information
Use only 110V power supply.
Disconnect the balance from the power supply when installing or moving the
balance.
Do not operate the balance in environments where flammable gasses or
vapors may be present.
Wear appropriate personal protective equipment (PPE) when operating the
balance.
Do not operate the balance if it is in any type of standing liquid.
Do not mix incompatible materials on the weighing pan.
Operating Guidelines
Do not drop objects onto the weighing pan.
Allow the balance to warm up for 15-20 minutes before using.
Do not exceed the maximum capacity of the balance. If OVER appears on the
display, the balance is overloaded. Remove objects until the amount to be
weighed is less than the maximum capacity of the balance.
Installation and Use Location
The balance’s working environment should be between 40°F and 105°F.
Install the balance on a flat, stable surface
Do not install or use the balance in locations subject to strong air currents or
vibration.
Do not install or use the balance in direct sunlight.
Do not install or use the balance in location subject to wide swings in
temperature or humidity.

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

Getting Started
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.
Press the ON/OFF button to turn the scale on. The scale will countdown
from 999999 while the unit updates.
Allow the scale to warm up for 30 minutes before using.

Calibration
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. For scales with a maximum capacity of
2000g or greater, use a calibration weight of at least 500g. The closer the
calibration weight is to the maximum capacity of the balance, the greater the
accuracy of the weighing. For example, with a 2000g maximum weighing
capacity, greater accuracy can be achieved by calibrating with a 1000g weight
versus a 500g weight.
Turn on the scale.
Quickly press ZERO three times. “AU-CAL” will be displayed on the lower
right corner of the screen.
Place no less than 20% of the full range of weights on the weighing pan.
The instrument will be calibrated.
Calibrate the instrument using any available reference weights.
The instrument can only be as accurate as the standard masses used.

NOTE: If this is the first time using the balance, repeat the calibration steps 2-
3 times. Please ensure that the scale is completely level and stable during
calibration. If, after repeating the calibration steps 2-3 times, the weighing is
still inaccurate, contact customer service for assistance before making a
return.

Unit Conversion
Press and hold the MC button to switch between the available units of
measurement, e.g., g, ct, oz, kg, oz, t, dwt, ozt, etc.

Counting Function
When using the counting function on the scale, the accuracy may be
adversely affected if too few samples are added, or, if the sample weight
is very low. Therefore, with very light samples, it is best to start with a
higher number of pieces.
If you receive either alarm, the sample size should be increased by
number of pieces, weight of pieces, or both. The scale will function in
either of these alarm states, but not accurately.
If the sample is too light or there are too few samples on the weighing
pan, ▼ will display on the screen. It will display above the LS if the sample
is too light and/or above the AS if there are too few pieces in the sample.
When using the scale for counting and you are finding inaccuracies, be
sure the scale is not operating in one of these alarm states. If it is, try
increasing the sample size or piece weight first before returning the
product.
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.

PCS/SET
This counting function is used to count the number of parts by
extrapolating values from the original sample.
Count the number of units in a sample.
Place the sample on the scale.
Input the number of pieces in the sample by using the numerical keys.
Press PCS/SET to confirm.
When more units are added, the counting window will show the 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.
Piece Weight Alarm
Important!

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 (33kg) will be displayed.
Place the first sample on the weighing pan.
Once the weight is shown, press M+.
Remove the first sample from the weighing pan. The display will return to
“0.”
Place the second sample on the weighing pan.
Press M+ again.
Remove the second sample from the weighing pan. The display will return
to “0.”
Repeat this step for each sample.
Once all samples have been weighed and removed, press M+ and the
entire weight and count will be displayed.
Press MC to clear all data.

Press PRINT/CAL to confirm.
Press TARE/MENU (page up).
After selecting the desired baud rate, e.g., 9600, press PRINT/CAL to
confirm.
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.

Troubleshooting
14
If these troubleshooting measures do not solve the problem, contact
customer support. The balance should be serviced by authorized technicians
only.

Factory Testing
Testing is performed to verify that the margin of error is less than .03g for a
.01g balance.
Margin of Error
Your balance has undergone extensive quality control (QC) testing at the
laboratory prior to shipment. The following QC tests have been conducted:
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.
Linearity
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. In
order to pass the repeatability test, each reading must fall within 1999.97g and
2000.03g.
Repeatability
Four points testing is conducted by placing a weight on each of 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.
