Method 1 (using an ST Analyzer and a Transducer)
Position the pulse unit in a vice. Remove the oil plug positioned on either the front (A) or the back (B) of the pulse unit. Add a small amount of oil to the pulse unit.
Assemble the tool and measure the pulse frequency.
If the pulse unit frequency is in the specified range the amount of oil is correct.
If the pulse unit frequency is too low reduce some oil and measure the pulse frequency again.
If the pulse frequency is to high add some oil and measure the pulse frequency again.
