7.4 Variables (VAR-1–VAR-16)
Sixteen variables are available to perform customized calculations. By combining
any of the measured values according to specific requirements, the user can generate
new data. With a variable, analog Vac and Iac measurements, for example, can
produce Pac data.
The variables are calculated in the order VAR-1–VAR-16. This can be important to
know when the formula for one variable contains another variable. For example:
VAR-1 calculates Pac, and VAR-2 determines Eac based on VAR-1. The settings for
the variables can be made in the menu “Setup…Plus I/O…Variables”
