Frequency Counter - Period Measurement (msec)
If no triggers are detected, or if Trigger is not active, 'No Trig' appears instead of a msec period value.
FcountMode=msec or FcountMode=2 sets the Frequency Counter to msec mode. See Macro Notes under Frequency Counter - Hertz Measurement for the complete list of mode names and numbers.
Freq is an internal variable that holds the current Frequency Counter readout value, dependent on the chosen mode (Hz, RPM, msec, Total, or SpecTot). You can assign it to a variable such as F via F=Freq, or you can display it via Msg=Freq, or use it directly in an expression.
Total holds the count of total cycles counted since the last Reset, valid during Hz, RPM, or msec modes. This allows macros to get the Total value even when these other modes are active. Note that this does not work in SpecTot mode.
