KEYBOARD CONFIGURATION

POWER ON

When turned on, your instrument will begin a 10 second display test. At the end of the test, your instrument’s serial number will be displayed. To bypass this test press the MODE button.

SETTING FUNCTION LIMITS

To set the limits, the instrument must be turned on and the kart’s engine turned off. Press and hold the MAX RECALL and MEM RECALL buttons simultaneously until the bottom display flashes. This will put the instrument into the Set Limits mode of operation, which is indicated by a flashing display. To increase the limit, press the MAX RECALL button. To decrease the limit, press the MEM RECALL button. To increase or decrease the limit by a large amount, press and hold either the MAX RECALL or the MEM RECALL button until the approximate limit value is reached. When finished setting the first limit, press the MODE button to set the next limit. Repeat the above procedure to set the remaining limits. Set limits at levels high enough for normal operation, but not so high that engine damage can occur before you can respond to a problem.

The tach limit requires the setting of two separate parameters. The first is the maximum RPM for safe engine operation. The second number is for tach calibration. In order to display the correct RPM for different engine types, the instrument divides the tach input signal by the tach calibration number. This number can be between .5 and 31. Select this number so that it will provide the correct display for your application using the MAX RECALL and MEM RECALL buttons.

To save the current limits and exit the Set Limits mode, press the STORE switch.

EXHAUST GAS TEMPERATURE

Exhaust gas temperatures typically run between 1100° F and 1350° F. The EGT on a properly tuned engine will increase rapidly as the throttle is opened and as the load on the engine is increased. At full throttle and full load the EGT will stabilize at a temperature dependent on the air/fuel ratio. Both a "too lean" or a "too rich" condition will be indicated by a lower than peak temperature. The "too lean" condition can damage your engine. An increase in coolant temperature or cylinder head temperature is usually an indication of this. The best way to determine what temperature is normal for your motor is to tune for good plug or piston color and then observe the temperature at various throttle settings.

TACHOMETER

For example, if your display shows 9.50, your RPM is 9500 RPM.

STORING DATA

The STORE switch, or the optional REMOTE STORE switch, can be pressed up to three different times to store the current values of each function into memory. The displays and the optional WARNING INDICATOR LIGHT will flash to indicate a successful store of information. After three sets of numbers are stored, additional attempts to store information will be ignored.

In addition, the instrument automatically stores a maximum value for each sensor during the current recording period.

MEMORY RECALL

To recall the first set of numbers stored in memory, press and release the MEM RECALL button. The contents of the first memory will be displayed and the left decimal point in the lower display will flash. Press MEM RECALL again to display the second set of information. The middle decimal point will flash in the lower window. A third press of MEM RECALL will bring up the last set of numbers and cause the right decimal point to flash. Press MEM RECALL once more to return to normal display mode.

MAXIMUM RECALL

The MAX RECALL button is used to display the maximum values recorded for each input. Recording of these values takes place automatically and requires no input from the user. To display maximums, hold down the MAX RECALL button. These values will be displayed until the button is released.

DISPLAY OF OVER LIMIT/OVER RANGE

When conditions exceed the range of the instrument, the display will show three bars at the top of the display where the over range condition occurs. This condition can also be caused by a bad or disconnected sensor.

ELECTRICAL INTERFERENCE

Severe electrical interference can cause the limits and calibration to reprogram themselves. If your instrument is doing strange things, put it in the Set Limits mode and check to see that the limits and calibration are still where you set them.

OPTIONS

There are three optional features that can be added to your DT-32K2. To have any of these options added to your instrument, send it to the address at the end of these instructions.

WARNING INDICATOR LIGHT

The optional WARNING INDICATOR LIGHT flashes constantly when any of the set limits are exceeded. It will stop flashing when the conditions fall below the set limits. The WARNING INDICATOR LIGHT will also flash once when either STORE switch is pressed. Memory is full if the switch is pressed and the WARNING INDICATOR LIGHT does not flash.

BACKLIGHT

The BACKLIGHT lights the displays for use at night. To turn it on or off, press and hold the MODE and MAX RECALL buttons simultaneously. The BACKLIGHT is an optional feature; it will only work if installed.

REMOTE STORE

When mounted to your steering wheel, the REMOTE STORE switch allows you to store three sets of numbers while keeping your hands on your wheel.

BATTERY LIFE

An instrument not using a backlight will run for about 150 hours on a fresh set of AA alkaline batteries. With the backlight on, the battery life will be approximately 50 hours. Heavy duty batteries last about half as long as alkaline batteries. The percentage of battery life remaining will alternate in the lower window by holding down the MAX RECALL button. The instrument will also display "lo b" in the lower window to warn you of a low battery condition. At this time the temperature functions will become inaccurate, but the tach will display accurate information for approximately one hour.

POWER OFF

The unit will turn itself off automatically after 10 minutes if no tach input is detected or buttons are pressed. You can also turn the instrument off manually by pressing the OFF and the MODE buttons at the same time.

Any stored data will be lost when the power is turned off. View all stored information before turning the instrument off.
