You start where it says 'Defective Meter'. Follow to the battery check 'BC'. If the BC is ok, then you go to 'Auto-Manual'. If not, then you check your batteries, such as low voltage, or leaking. Just follow the steps, and it will lead you to a solution. Say the Auto-Manual check is not ok, so the next step is to 'Check on voltage at grounding unit'. If you get 0v at any of the three places to check, then the problem is one of two possibilities, a 'Defective Screw Fastening', or 'Disconnected Patterns'. Different sections of the chart reference the drawings at the bottom of the page, such as 'Poor adjustment of R3'. You can assume figures 18 and 20 are on another page, but for illustrative purposes, Fig. 19 shows the meter connection for testing 'Loose screws, unsoldered lead wire'. PF
