MEMORY RECALL
The MEMORY RECALL button is used to recall the
numbers stored in memory. To view the secondary function
in the window, press the MODE button at any time.
To recall the first set of stored numbers, press and release
the MEMORY RECALL button. The contents of the first
memory will be displayed and the left decimal point will flash.
Press MEMORY RECALL again to display the second set
of information. The middle decimal point in the window will
flash. A third press of MEMORY RECALL will bring up the
last set of numbers and cause the right decimal point to flash.
Press MEMORY RECALL once more to return to normal
display mode.
MAXIMUM RECALL
The MAXIMUM 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 MAXIMUM
RECALL button. These values will be displayed until the
button is released.
Press the MODE button to display the secondary function
(CHT) in the window. Then press the MAXIMUM RECALL
button to display the maximum for this function.
DISPLAY OF OVER LIMIT/OVER RANGE
When conditions exceed the set limits, the display will flash.
The instrument automatically switches to this function if it is
not being displayed.
When conditions exceed the range of the instrument, three
bars will show at the top of the display. This condition can
also be caused by a bad or disconnected sensor.
ELECTRICAL INTERFERENCE
If the instrument encounters excessive electrical interference
it will display three vertical decimal points. This indicates
that the stored data could be invalid. It can also indicate an
incorrect instrument or sensor installation.
Severe electrical interference can cause the limits and
calibration number 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 number
are still where you set them.
OPTIONS
There are three optional features that can be added to your
DT-31K1. To have any of these options added to your
instrument, send it to the address at the end of these
instructions.
BACKLIGHT
The BACKLIGHT lights the displays for use at night. To
turn it on or off, press and hold the MODE and MAXIMUM
RECALL buttons simultaneously. The BACKLIGHT is an
optional feature; it will only work if installed.
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 the STORE button or switch is pressed. Memory is
full if the switch is pressed and the WARNING INDICATOR
LIGHT does not flash.
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
MAXIMUM 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.
