Calibration

IMPORTANT: This tachometer is factory calibrated to

operate on 8 cylinder engines. For 4 or 6
cylinder engines, it is necessary to make
the proper adjustments to adapt this
tachometer to your cylinder range.

Locate the access hole on the back of the tachometer.
Move each of the two switches to the proper cylinder
selection according to the diagram illustration on the
right. Use a small screwdriver or an unwound paper
clip to change the switch settings.

NOTE: This tachometer has an air core meter. With
power off, it is normal for the pointer to leave
zero. When power is applied, the pointer will
move to the correct position.
