CruzPro Digital Timer with Alarms
The CT30 Digital LCD Clock provides accurate low cost
display of time, race and watch timers. Five levels of backlighting can be
selected and all set-up and calibration constants are saved to non-volatile
memory.
With a press of the button you can display
time-of-day, a downcounting race timer or start/reset/re-start a watch timer.
Both race and watch timers count up after reaching zero and both are easily
programmed. The time-of-day clock has 8 different programmable alarms for all
those radio schedules, weather fax warnings, etc. The clock can be set for 12 or
24 hour display format and is accurate to better than 5 seconds per day. The
clock is factory calibrated but can be adjusted with the front panel switches
and calibration data saved to non-volatile memory.
When used as a Watch Timer, the CT30 is programmable
with a time interval anywhere from 1 second to 99 minutes and 59 seconds. When
the DOWN key is pressed, the programmed time interval is displayed and starts
counting down to zero. When 10 seconds remain, the CT30 quietly
"clicks" down to zero. The Watch Person can press the DOWN key at this
(or any other) time, re-starting the watch timer without the alarm waking other
crewmembers. If the DOWN key is not pressed before the watch timer reaches zero,
an 85 dB alarm wakes everyone and the CT30 watch timer starts to count up from
zero. Disgruntled and sleepy crewmembers can tell at a glance how long the Watch
Timer has been asleep or treading water. All the other functions of the CT30 are
still available while in Watch-Timer mode.
The CT30 has a large LCD display yet draws only
0.018 amps. 5 levels of backlight (including OFF) can be selected from the front
panel and is saved to non-volatile memory.
The CT30 outputs NMEA 0183 serial data line at 4800
BAUD. This ASCII information can be sent to a computer or used to repeat the
display information elsewhere such as the CruzPro RP30 NMEA Remote Data Repeater
