Calculate Tray Lift.
The air flow through the chamber causes lifting of the sample tray and balance; the
amount of lift should be measured after installation and should be checked from time to
time.
Load the chamber with an empty sample basket assembly and catch tray, after it has
reached its normal operating temperature (e.g. 500 °C). Allow the baskets to heat up
for 10 minutes.
The main chamber temperature is displayed on the screen for convenience (see Fig
49.). If the temperature is below 100 °C and a calculation is attempted, an error
message pops up.
When the Calculate Fan Lift button is pressed the ABA automatically performs the
following sequence:
1. Stop the extractor fan
2. Tare the balance
3. Start the extractor fan
4. Wait for the system to stabilize
5. Take a weight measurement and store the result in flash memory
6. Stop the fan
7. Indicate the calculation is complete
8. Write a message to the Event Log
A progress bar shows the relative status of the calculation and when the procedure has
finished the word Complete appears across the bar and the yellow back arrow changes
to a green tick (see Fig 50.).
The calculation can be repeated as many times as required.
When a test is operated the lift correction factor will automatically be applied.
