seconds and no temperature measurement will be allowed. The thermometer will automatically shut off
after 5 minutes of the error display.
Internal Microprocessor Test
During each thermometer display test a check sum of all program memory is calculated and compared
against a reference stored in the program memory. An error in the check sum will cause the
malfunction error to flash, the horn will sound with a double beep every 10 seconds, and no
temperature measurement will be allowed. The thermometer will shut off after 5 minutes of the error
display.
Battery Life
Shelf Life
The shelf life of carbon zinc chloride or alkaline batteries should be at least three years when stored at
70°F. The storage life degrades rapidly with increased temperature.
Temperature Taking Without Backlight
The Model 600 should operate continuously for about 2,000 hours when the backlight is not used. If an
operating time of 2 minutes per temperature is assumed then the potential number of temperatures
that can be taken should be about 2,000 hours @ 30 temperatures/hour = 60,000 temperatures.
Temperature Taking With Backlight
The backlight uses about 20 times more power than the rest of the thermometer. If 20 seconds of
backlight usage is assumed for each temperature taken then the number of temperatures that can be
taken should be about 17,300 temperatures.
C/F Mode Switch
The display mode may be changed between Fahrenheit and Celsius at any time prior to, during, or
after taking a temperature by activating the C/F slide switch. The numbers will change as the switch is
activated, however, the C/F indicator is only visible at the end of a normal mode temperature.
Normal/Monitor Mode Switch
The selection of normal or monitor mode operation should be made prior to turning on the thermometer
by setting the normal monitor switch to the desired position. Once the thermometer has been turned
on, a change from normal to monitor mode may be made at any time, however, a change from monitor
to normal will cause the horn to beep twice and the thermometer to shut off. This error indication and
shut off prevents a normal mode temperature from being started with the probe already in place.
