After a run push “Recall” to see highest RPM:
(RED button) The ignition switch must be ON to recall. However you can shut off the ignition, turn it back on, and still retain the reading. Push “Reset” before going back out.
Change to 4 or 6 cyl use:
This is done from the front unlike other tachs. Turn on ignition to power tach. Press and HOLD BOTH Reset & Recall buttons. Pointer will jump to 10,000 RPM, then drop to 0 (continue to hold both for 10 seconds). Pointer will go up to 8000 RPM, indicating 8 cyl. (you can now release both buttons). Push Recall to change. 6000 = 6 cyl., 4000 = 4 cyl. When you get the setting you want push Reset to save setting. Tach will return to normal function.
Misc. Notes:
• Be sure all electrical connection are tight. Clean the surface for ground connection. Use insulated connectors or soldered.
• Mount tach where it will not receive excess vibration or heat.
• If wires go thru the firewall use a grommet to prevent chafing and shorts. Keep wires away from exhause heat.
• Tach is water resistant but NOT waterproof. If you wash the car out cover the tach to keep it dry.
