• Check wire winding: Ensure the pickup wire is wrapped tightly around the spark plug cable without slack (secure with the supplied zip tie). If the reading is weak, increase the number of wraps; if erratic, reduce wraps.

• Firing pattern adjustment (B02-H059 only): Inaccurate RPM readings often mean the engine fires once every two revolutions (1P2R) or once per revolution (1P1R). Adjust the firing pattern setting in the menu until the displayed RPM matches engine idle specifications.
