Equation Types
Combinations of measurement functions and element numbers (e.g., Urms1) can be
used as operands to create up to eight equations (F1 to F8). There can be up to 16
operands in one equation. Some operands cannot be computed in measurement modes
other than normal measurement mode. For details, see appendix 12.
