11, injects an internally generated frequency into the unit.
When using this feature, F (TEST) is equal to 120 Hz and is used in the
following equation.
Alternate or external oscillator may be used to supply a test frequency. In
this method, the external oscillator is connected to the signal input ter-
minals. The oscillator ' s output frequency is set to equal F (MAX) as in-
dicated on the frequency counter. For this approach, use F (MAX) in the
following equations for F (TEST).
Regardless of the method used, begin by calculating the following set points
indicated by Equation I through Equation 3. Use the frequency F (TEST)
depending on calibration method chosen above

The signal conditioner may be calibrated with an internal "TEST" frequency
or an external oscillator used in conjunction with a frequency counter.

For analog, go to Section 3.4.
For pulse, continue to step 3.
