Auto Meter 6388 - Manual

General Information
This instrument utilizes a single LCD to display odometer and two trip odometer mileages. Press the Trip button on the dial window to cycle between odometer,
Trip 1, and Trip 2 displays on the LCD. Pressing and holding the Trip button for more than 2 seconds while viewing either Trip display will reset the trip currently
being displayed. The odometer cannot be reset.
NOTE: The odometer on the speedometer portion of this instrument will show some mileage less than 5 miles (8km).
This is a result of factory testing to ensure optimum quality.
TIP: Auto Meter always recommends performing the calibration process for best speedometer accuracy.

The electronic speedometer in this instrument is designed to operate with an electrical speed sender. The speed sender signal range must be between 500
and 400,000 pulses/mile (310 and 248,500 pulses/km). Any speed sender or electronic module that meets the following two conditions can be used:
1. Pulse rate generated is proportional to vehicle speed.
2. Output voltage within the ranges listed below:
a. Hall effect sender, 3 wire (5 to 16V)
b. Sine wave generator, 2-wire (1.4 VAC min.)
c. 5v Square Wave (CMOS)
Recommended – Auto Meter Hall effect sender, 3 wire, 16 pulses/revolution

INSTALLATION INSTRUCTIONS
DIGITAL SPEEDOMETER
Installation Tips
1. A 12 V power source MUST be used to power this speedometer. A 12V motorcycle battery is a good alternative for cars without batteries.
A battery with minimum 5 amp hour rating is recommended.
2. Wherever possible, solder wire connections and avoid crimp-type connectors. This will minimize loose connections that could cause problems later.
3. Make sure you have a good ground to engine and battery negative terminal.
4. Wire installations should be neat and tied down to prevent tugging and fraying of wires at connections.
