What is hour meter tachometer gauge:

The operation of the tach / hour meter is triggered by approximately 5 feet of shielding and an external lead wound around the spark plug wire of the engine. Because the device is triggered by the spark of the engine, the hour and RPM show the actual operation. We can use it on ships, cars, motorcycles, etc.The hour meter / tachometer eliminates complex multi wire connections. One end of the wire is wound around the spark plug wire, and the other end is fixed in the channel on the instrument. The timer displays up to 9999.9 hours at 1 / 10 hour intervals or 99999 hours at 1 hour intervals, while the tachometer can accurately reduce the speed to a resolution of 10 rpm. With the help of flash alert (TM), the programmable alarm can remind the operator of the type of maintenance required.

How to set the tachometer:

When you see the gague, press and hold the button for about 1 minute. 3 seconds until you see the clock display zero on the screen, then release the button. The screen should now flash for 12 hours. If you want to set it to military time, press the button again. Once you see your preference (12 hr / 24 hr), ignore it until minutes appear and flash. Then press the button to change the time. It will first change the minutes; Every time you press the button, it changes for one minute at a time. If you press and hold the button, it speeds up the minutes and flips the hours.All devices are used for negative grounding, positive grounding or isolating the electrical system. If the instrument is connected with reverse polarity and cannot operate until it is properly connected make. All units are powered by 12 VDC. Optional for 24 VDC applications Atvc12 / 24 converter must be used.

RPM input signal voltage: minimum 1.5 VRMs, from magnetic pickup or Alternator (at least 3 poles).

Accuracy: tachometer: ± 2% of full scale. Timer: ± 0.01% hour, ± 1 count.

Temperature range: - 5 ° f to 185 ° f (- 20 ° C to + 85 ° C).
