If after completely reading this guide you have questions regarding the operation or installation of your instrument(s),
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 requirement.
Locate the access hole on the back of the tachometer.
Remove the black composite cover by prying it gently
upwards with a small screwdriver. 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. Replace cover when calibration is
complete.
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.
