from the setting mode. All digits will stop flashing to indicate
setting mode has been exited.
VIEWING THE TIME-OF-DAY/DATE
To view the time-of-day/date, slide the DISPLAY switch to the
DATE/TIME position.
DISPLAYING °F OR °C
To display the temperature readings in Fahrenheit or Celsius,
slide the °C/°F switch to the desired position.
MINIMUM AND MAXIMUM MEMORY
The minimum temperature recorded into memory is the
minimum temperature achieved since the last time the
memory was cleared. The maximum temperature recorded
into memory is the maximum temperature achieved since the
last time the memory was cleared.
Minimum and maximum temperature memories are NOT
programmable (see HI/LO ALARMS).
Below are the FOUR different memory features:
• MIN/MAX: Minimum (MIN) and maximum (MAX) tempera-
ture achieved with time-of-day and date occurred since
the last time the memory was cleared.
–AND–
• 24-HOUR: Minimum (MIN) and maximum (MAX) tempera-
ture achieved for each hour within a 24-hour period.
• 7-DAY: Minimum (MIN) and maximum (MAX) temperature
achieved for each day within a 7-day period.
–OR–
• 31-DAY: Minimum (MIN) and maximum (MAX) tempera-
ture achieved each day during a 31-day period and the
time-of-day it occurred.
