The Two Modes of the DT-43KL
This instrument has two basic modes of operation, Set Limits and Monitor.
A. Set Limits mode is necessary before using your unit for the first time and if you use it on different engines. The limit helps you
prevent possible engine damage.
B. Monitor mode is used while operating your kart to watch your engine’s exhaust gas temperature for irregular activity.
A. Setting the Function Limit On Your DT-43KL
Before using your DT-43KL, be sure to set the EGT operating limit. The limit allows the instrument to give you a visual warning (the
display flashes) if the input exceeds it’s limit. The limit should be set at a level that allows you to react to the visual warning before
engine damage occurs.
• Enter Set Limits mode by pressing the SETL button. The instrument is now in Set Limits mode, which is indicated by the flashing
display.
• To change the number being displayed press the ← or the → button. Hold either of these buttons down and the number will
change faster.
• To save the current limit and return to Monitor/Record mode, press the Exit/Power button.
Note: Set the limit at a level high enough for normal operation, but not so high that engine damage can occur before you can respond
to a problem.
B. Monitor Mode is Used While on the Track
When your instrument is powered on, it is in Monitor mode. This is the mode the unit will be in so you can observe your EGT
function. During Monitor mode you can make quick tuning adjustments to your powertrain that allow you to run safe and fast. The
instrument will visually warn you, by flashing the display, if your engine exceeds it’s set limit. This limit allows you to avoid engine
damage.
• To view your maximum EGT reading since the engine was turned on, press the ← and the → buttons at the same time.
• The backlight is used to illuminate your display for use at night. Press the LIGHT button to toggle the backlight on or off. The
backlight can only be turned on or off while in Monitor mode.
The DT-43KL Uses One AAA Batteries (not included)
To replace the one AAA battery, remove the battery holder on the back of the instrument. Observe polarity when replacing the battery.
The DT-43KL can run, without a backlight, for 200 hours on one AAA battery. When using the backlight, the battery will power the
instrument for 50 hours.
Troubleshooting
The following are explanations to some commonly asked questions.
What are those letters on the side of my display?
There are two annunciators that may be displayed on the left side of your display.
EGT stands for Exhaust Gas Temperature
ERR stands for Error and could mean that your instrument has encountered extreme electrical interference. This can possibly cause
the instrument to reprogram it’s limit and calibration number.
Why is the Display Flashing?
This signifies that you are either in Set Limits mode or that your engine exceeded it’s limit.
