5.3 Performing Statistical Calculations on Measured Values
114
Statistical calculation results are displayed on the screen.
Additionally, results can be printed using an RS-232C printer. Once statistical calculation
results have been printed, the data can be automatically deleted.
Before printing, select the
[PRINT] interface setting.
See: "Printing (Using an RS-232C Printer)"(p.237)
The number of valid samples can be confirmed on the Calculation Results screen.
• When the number of valid samples is zero, no calculation results are displayed.
• When only one valid data sample exists, no standard deviation or process capability indi-
ces are displayed.
