Batteries Not Needed

When your vehicle is running, the DT-50S series instrument gets power from the lighting coil. To use your instrument for an
extended time without power from the lighting coil, you can buy a wall adaptor to power your instrument.
When your engine is off, the instrument is powered by super caps, which are similar to rechargeable batteries. They will recharge in
ten minutes when your engine is running. When charged, the super caps will run your instrument, without backlight and warning
lights, for about 20 minutes. LC will be displayed when the super caps need to be recharged.
How Time is Displayed
Time is displayed as a 20 second timer. After 19.99 seconds the displayed time wraps back to zero. To see total time, up to 19:59
minutes, press and hold the Time button.

Setting Limits and Warning Lights

Limits and warning lights warn you of conditions that could be harmful to your vehicle's engine. They should be set at levels that
allow you to react to the visual warnings before engine damage occurs.
There are two ways to set your limits and warning lights:
♦ With Your Instrument (see the next pages).
♦ With Your PC, download cable and configuration software (page 9).

Function limits are set in the following order: Delay Time, Temp (C1), Temp(C2), Temp(C3), Water Temperature, Tach (RPM1),
Tach calibration number, JS(RPM2), and JS calibration number (minus any functions that you do not have). Also, if you are not using
any functions on your instrument, set its limit to any number greater than 200.
About Delay Time (Optional, for Racing)
Some sanctioning bodies do not allow racers to use infrared beacon transmitters and receivers. If this is true for you, set your
delay time to .1.
The delay time allows your instrument to ignore extra beacon signals at the track. Delay time is the time, in seconds, that your
instrument ignores beacon signals after receiving a signal. The delay time must be less than your best possible time between beacons
(lap), or the instrument will miss your beacon signal. Delay time is set in
For example, if it takes you approximately 16 seconds to complete a lap, set your delay number for 14 or 15 seconds. After your
instrument receives its first beacon signal, it will ignore all signals for 14 seconds
*Note. If you are not a racer, set your delay time to .1.
