Chap. II - Multi-Diag Motortester
1. INTRODUCTION
By connecting Multi-Diag Motortester (hereinafter referred to as the Motortester) to Multi-Diag Scope, this set
becomes a typical car oscilloscope that can display important diagnostic ignition variables of spark ignition
engines, such as high voltage on spark plugs and coil primary voltage. It also allows measuring the engine speed
and dwell angle.
If you add other sensors from optional accessories to the Motortester, you can construct a complete universal
motortester for spark ignition engines and diesel engines.
