Calculation method

Calculation method

Applied depth (mm)

Depth=volume mm³/collector area; divide by tip count.

Calibration depth per tip (mm/tip)

Depth=volume mm³/collector area; divide by tip count.

Assumptions & limits

Assumptions & limits

  • Calculation uses the entered values and stated mathematical model; quantities must use the labelled units. Supported limits: All required fields must be finite values of the exact declared type and within displayed bounds. Lists contain1–1000 finite numbers. JSON tables are numeric rectangular rows, at most100 rows and30 columns; individual tools have stricter shape/domain constraints. Depth=volume mm³/collector area; divide by tip count.
