SPT105 adds adjustable socket height. Its lower firing-rate label differs between the page and manual, so do not use a single 0-rpm figure without version confirmation.<\/p><\/div><\/details><details><summary>What Is The Difference Between SPT105 And SPT301 \/ SPT360?<\/summary><div class=\"autool-faq-answer\"><p>SPT105 provides two positions and no digital setting display. SPT301 provides one reference and two test positions; SPT360 provides one reference and four test positions. SPT301 and SPT360 list 200\u20139000 rpm simulated settings, which are bench firing-rate labels rather than real engine load.<\/p><\/div><\/details><details><summary>Should I Close The Protective Cover Before Testing?<\/summary><div class=\"autool-faq-answer\"><p>Yes.
