2
For information about function input from the MATH function menu, see “Using the MATH
Menu” described below.
*
3
Tolerance cannot be specified in the Math input/output mode. If you want to specify
tolerance, use the Linear input/output mode.
*
4
For Σ calculation in the Math input/output mode, the pitch is always 1. If you want to specify
a different pitch, use the Linear input/output mode.
