Battery Installation
Two AAA batteries power the DT-50K. These allow the instrument to run for 40 hours with the backlight on and 150 hours with the
backlight off. The instrument will display , signaling that the batteries are low, several hours before the functions becomes
inaccurate.
To replace the batteries, remove the screw from the battery door on the back of the instrument. Replace the two batteries, observing
battery polarity.
If your instrument is stored for a long period of time, remove the batteries.
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 below).
♦ With Your PC, download cable and configuration software (page 9).
