Indoor/Outdoor Thermometer  (630-0869)   Display       Faxback Doc. # 6794

Temperature Display

The temperature display normally updates every 10 seconds.  However, in
the case of a rapid temperature change, it will take the thermometer
several minutes to fully register the new temperature.  For example, if
the outdoor temperature drops suddenly from 73 degrees F/23 degrees C to
59 degrees F/ 15 degrees C, the thermometer display may show 68 degrees
F/20 degrees C at the next update, then 63 degrees F/17 degrees C a minute
or so later, until the new temperature of 59 degrees F/15 degrees C is
reached.

Temperature Ranges

Because indoor temperatures vary less than outdoor temperatures, the
indoor and outdoor temperature display ranges are slightly different.

When the indoor temperature is above 122 degrees F/50 Degrees C or below
23 degrees F/-5 degrees C, the display blanks out or shows all symbols.

When the outdoor temperature is above 158 degrees F/70 degrees C, HHH
appears on the display.  When the outdoor temperature is below -58 degrees
F/-50C, LLL appears on the display.

Note:  When the indoor or outdoor temperatures return to within the
       measurement range, the LCD display automatically returns to normal.

Temperature Memory

The thermometer automatically stores in memory the highest and lowest
indoor and outdoor temperatures since you last reset the thermometer or
replaced the batteries.

Reading the Recorded Temperatures

To display the highest or lowest recorded temperatures, press MAX or MIN.
The highest or lowest recorded temperatures appear on the display.

To return the display to the current indoor and outdoor temperatures,
press MAX or MIN again.  MAX or MIN disappears from the display and the
current indoor and outdoor temperatures reappear on the display.

Clearing the Recorded Temperatures

Press RESET to clear the highest and lowest temperature measurements from
the thermometers memory.

MAX, MIN and -1888 appear on the display for about 3 seconds.  Then the
current temperature readings reappear on the display.
