The results are used to calculate the error in the volume added and the syringe precision. There are three verification modes available:
· Fully automated–The balance is connected to the instrument. The system makes the additions and calculates the results.
· Partially automated–The balance is not connected to the instrument. The user does the balance readings and the system calculates the results.
· Dispense only–The system only makes the additions. The user does the balance readings and calculates the results.
The syringe verification kit includes all of the necessary items: dispensing tips, tubes, syringe holder, pipette holder, support stand, software key and label with the license number. Make sure to keep the label with the license number. A license key is necessary to enable the syringe verification option on the instrument. The first time the option is selected, the instrument shows the MAC address and the Firmware version. Send the MAC address, firmware version and the license number to the manufacturer or a sales representative to get the license key. Note: The license key is only necessary when the option is selected for the first time. Items to collect:
· Analytical balance with resolution 0.1 mg, repeatability 0.2 mg and uncertainty 0.2 mg · Temperature sensor · Deionized water “quality 3” (ISO 3696)

NOTICE
The applications installed on the instrument have been pre-defined to optimize the measurement process. Changing these default application parameters will have an effect on the measurement process and measurement results. Only qualified personnel should change these parameters or use the instrument in Expert mode. Refer to the application note before changing any parameters.

NOTICE
In Basic mode changes to parameters are secure. In Expert mode changes to parameters are not secure and can cause the application to run incorrectly.

NOTICE
The Active parameter is available to change in some parameter groups. It specifies if the method should be used during the analysis. Changing this from Yes to No means that the method will not be used which will have an effect on the measurement process and measurement results.

NOTICE
The Hide result parameter (e.g. R2 hide, R3 hide, etc.) is available to change in some parameter groups. It specifies if the result is shown on the display. Changing this from Yes to No means that the calculated measurement result will not be shown. This will not have an effect on the measurement process and measurement results.

The parameters available for change can be different for each instrument configuration and the application being edited. The parameters marked with an “x” are available for change.
