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
The MEMORY RECALL button is used to recall the numbers
stored in memory. 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 the maximums, hold down the MAXIMUM
RECALL button. These values will be displayed until the
button is released.
DISPLAY OF OVER LIMIT/OVER RANGE
When conditions exceed the set limits, the display where the
overlimit condition is occurring will flash.
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
If the instrument encounters excessive electrical interference it
will display three vertical decimal points in the tach display.
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 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-
33K3. To have any of these options added to your instrument,
send it to the address at the end of these instructions.
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.
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 MAXIMUM
RECALL buttons simultaneously. The BACKLIGHT is an
optional feature; it will only work if installed.
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 MAXIMIM 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.
