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 switch hole on the back of the tachometer.

Use an unwound paper clip to move each of the two

switches to the proper cylinder selection according to

the diagram illustration on the right. Apply included label

over switch hole.

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.
