When Fcal is On, the frequency calibration specified by the following High, Low, Calibration Table, and Units settings is applied to the current Trigger Source channel for the current Frequency Counter mode. Only Hertz, RPM, and msec modes are supported.
Separate Fcal On/Off states and calibration settings are maintained for each Trigger Source and counter mode.
The Fcal dialog does not need to be open to make changes to this control. However, you must make sure the desired Trigger Source and Frequency Counter mode are set in order to change the relevant Fcal On/Off state.
Fcal=1 sets Fcal On for the current Trigger Source and counter mode, Fcal=0 sets it Off, and Fcal=x toggles the current state.
