This document discusses various tools and equipment used in automotive work. It describes vernier calipers, micrometers, dial gauges, cylinder gauges, circuit testers, engine scanners, and equipment for blocking, jacking and lifting vehicles. It provides details on how to check and use these tools, including taking measurements and reading measurement scales. The goal is to introduce various tools and equipment technicians use and how to properly handle and get readings from them.

8. 1) Checking micrometer
(1) Pastikan clamp sudah kendor
(2) Bersihkan seluruh instrumen.
(3) Putar ratchet berhenti dan periksa rotasi spindle.
(4) Check the zero point.
(5) Sesuaikan zero point.
