Digatron DT-46KL Manual

Introduction

The DT-46KL is Digatron's small, easy to use, digital engine monitoring system. This instrument
was designed for the customer who wants to know how their engine is functioning without
spending a lot of time and money. This instrument monitors tachometer (Tach) and cylinder head
temperature (CHT) with backlight and limits to warn you of possible engine problems.

The Two Modes of the DT-46KL

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. Limits help you prevent possible engine damage.
B. Monitor mode is used while operating your kart to watch your engine RPM for irregular
activity.
A. Setting the Function Limits On Your DT-46KL
Before using your DT-46KL, be sure to set the operating limits for each input. Limits allow the
instrument to give you a visual warning (the display flashes) if any of the inputs exceed their
limit. Limits should be set at levels that allow 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.
•
When you are finished setting the first limit, press the Function button to set the next limit.
•
Repeat the above procedure to set the remaining limit and the Tach calibration number.
•
To save the current limits and return to Monitor/Record mode, press the Function button.
Note: 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.
Limits are set in the following order: CHT, Tach and the Tach calibration number. Tach requires
two separate parameters. The first is the maximum revolutions per minute (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.
The most frequently used numbers are:
.5 - for some single cylinder 4 cycle motors
1 - for single cylinder 2 cycle and some 4 cycle motors
2 - for 2 cylinder 2 cycle and 4 cylinder 4 cycle motors
