MODEL 600 OPERATIONAL CHARACTERISTICS
The Diatek Model 600 Digital Thermometer is a portable instrument for measuring patient
temperatures over the 84°F to 108°F (28.9°C to 42.2°C) range. The Model 600 features an LCD
readout with backlight, interchangeable probes, disposable prove covers, disposable batteries with a
capacity for up to 45,000 temperatures, automatic power shutdown, both normal and monitor modes of
operation and self-calibration/test capability.
Normal Mode
Removal of the probe automatically turns on the Model 600 and places it in the predict mode when
selected by the normal/monitor slide switch. All segments of the display except the pulse timer are
lighted simultaneously for 6 seconds as a display test and the horn is tested for 0.1 seconds. The
display will read 84.0 (28.9) with the down arrow on until the probe exceeds that temperature and will
ten display a rising temperature for about 30 seconds.
When the readout has stabilized, the horn will sound for 1 second, the “F” or “C” symbol will light and
the display will remain fixed indicating the end of the temperature taking cycle. The displayed
temperature will be the actual probe temperature plus a computed correction factor. The probe
temperature is sensed about 4 seconds from turn on to correct for ambient probe temperature
variations. If the temperature measurement cycle is not completed within 5 minutes from turn on, the
thermometer will turn off at that time. A temperature in excess of 108°F (42.2°C) will cause an error
condition to be indicated by the horn beeping twice every 10 seconds and the up arrow blinking. Five
minutes of this error condition causes the thermometer to turn off. Returning the probe to its holder
and then removing it will restart the thermometer.
Note: The normal mode display is peak reading and will not read down.
Monitor Mode
Removal of the probe automatically turns on the Model 600 and places it in the monitor mode when
selected by the normal/monitor slide switch. All segments of the display except the pulse timer are
lighted simultaneously for 6 seconds as a display test and the horn is tested for 0.1 seconds. The
display will then indicate the actual probe temperature, updating every 1.5 seconds as long as it
remains within the 84°F to 108°F (28.9°C to 42.2°C) range, and will show the appropriate up or down
arrow when outside this range. Five minutes of operation outside the operating range will cause the
thermometer to turn off.
Pulse Timer
Pressing the pulse timer switch at any time causes the 30 second clock type display to start. One
additional segment is turned on each second until 30 seconds has been reached at which time the
timer display goes blank. The horn sounds for 0.1 second at 0,15, and 30 seconds. Pressing the timer
switch while the timer is running causes the timer to restart. The switch will not respond if pressed
sooner than 1.5 seconds since the last timer activation.
Backlight
The backlight is activated as long as the backlight switch is pressed and the thermometer function is
active. In the predict mode, activating the backlight any time prior to the end of the temperature taking
cycle will cause the backlight to turn on for 5 seconds when the final temperature has been reached
and the horn sounds. No backlight is available when only the pulse timer is in use.
