H/L setpoint type: Dial knob clockwise for the High (H) set point
until Vset = 15.8V. The Vread value will equal the upper set point
of the regulator (it will not match Vset). Dial the knob counter
clockwise for the Low (L) set point until the Vset = 11.4V. The
Vread value will equal the lower set point of the regulator (it will
not match Vset). Note: Dial settings between the High (H) and
Low (L) will not be accurate.
PWM type: Dial knob clockwise/Counter clockwise to set Vset
value. Vread should increase or decrease accordingly.
If the regulator supports DFM, whilst Vset changes the value
should also change.
Pressing the control knob makes the WAI1000 go back to the
protocol selection screen.

There are two types of C terminal regulators H/L setpoint type
and PWM type the two methods for testing Vset/Vread are
described below.

Note: Small difference between the voltage is acceptable. What is important is the appropriate reaction
of the alternator – increasing or decreasing the output voltage according to the required voltage and
DFM value.
