PRO 3 ALT
(units with Alternator input)
RPM Calibration
Be advised that all PRO 3 units made after October, 1997 are set up to receive RPM
data via alternator input. If you have a PRO 3 with a serial number of 1236 or later,
then the installer must use this page to calibrate the PRO 3.
The PRO 3 with alternator pickup must be calibrated properly in order for the
unit to maintain the engine RPM correctly. Carefully follow the procedures
below to calibrate:
Press the button marked “ IDLE ” to bring the engine to an idle. The word “IDLE” will appear
in the PRO’s display window.
Press the button marked “ RPM ” to enter into RPM mode. Indicator lights located above the
RPM and PSI buttons let you know which mode you are in.
‘Double-click’ the button marked “ IDLE ” (press the button twice quickly). The word “CAL”
will begin to flash in the display.
Double Click the “ IDLE ” button again. The word “CAL” will stop flashing and will appear as
a steady reading in the display.
Press the “ PRESET ” button. The words “SET” and “1200” will alternately flash in the
display.
Use the “ INCREASE “ ( s ) or “ DECREASE “ ( t ) switches to change the engine speed until
the reference tachometer reads “1200” (The displayed value will NOT change)
When the reference RPM matches the displayed RPM (1200), press “ PRESET “ again to
accept the setting. The display will now show “ IDLE “ and the engine RPM will drop down to
idle.
The RPM reading is now calibrated.
