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

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.
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.

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.
