When power is applied to the unit, the start-up screen appears for a few seconds.

This screen shows the date of the last gas calibration and what fuel type and RPM

input the analyzer is going to use.

The analyzer then proceeds automatically to the warmup screen. After a two

An oil temperature probe and extension lead

can be connected to the Control Module

WARNING - Adjust the clamp to the length of

the vehicle oil dip stick before inserting into the

dip stick tube on the vehicle
