Attach a reflector tag (approximately 10 mm long) to the calibration shaft (crankshaft).
Plug the RPM-8000-PRO into the cigarette lighter socket outlet or connect directly to the battery. Make sure
polarity is correct when connecting to the battery.
Start engine – turn on lights and rear window heater – turn off the air conditioning system and other inductive
loads – run engine at constant no-load speed – connect TTL output from laser to “Cal. Ext. In” jack on the RPM-
8000-PRO.
Point the laser beam at the reflector tag at an angle of about 90°. The RPM-8000-PRO is calibrated when both
the laser and the RPM-8000-PRO show the same speed, the red LED stops flashing and the green LED is
permanently illuminated. The calibration data is stored permanently in the device and therefore is not lost when
power is turned off. The data is only overwritten when the device is recalibrated.
The “Cal Int.” button should not be pressed while using the external calibrated process. The RPM-8000-PRO
is now set to the actual speed of the shaft with reflector tag and is shown on the screen. A DC voltage of 1V per
1000 rev/min is applied to the analog output.
