ABOUT THE MEMORY
Minimum and maximum memories are NOT programmable.
The minimum temperature and humidity recorded into
memory are the minimum temperature and humidity achieved since the last time the memory was cleared. The
maximum temperature and humidity recorded into memory are the maximum temperature and humidity achieved
since the last time the memory was cleared. The minimum and maximum memories are maintained over the period
since the memory was cleared.
VIEWING THE HUMIDITY MEMORY
To view the humidity memory, press the
HUMIDITY MEMORY button. The maximum humidity reading achieved will
be displayed (“MAX” will appear on the display). Press the HUMIDITY MEMORY button a second time, within 10
seconds, to view the minimum humidity achieved (“MIN” will appear on the display).
Note:
Ten (10) seconds after
pressing the HUMIDITY MEMORY button, the unit automatically returns to the current temperature/humidity reading.
Press the HUMIDITY MEMORY button a third time, within 10 seconds, to return to the current humidity reading.
CLEARING THE HUMIDITY MEMORY
The minimum and maximum humidity memory may be cleared independently. To clear the desired humidity memory
(MIN or MAX), press the CLEAR button while that memory value is being displayed (see the “Viewing the Humidity
Memory” section). The display will show “--” for approximately 8 seconds and will then display the current humidity
reading. VIEWING THE TEMPERATURE MEMORY To view the temperature memory, press the TEMP MEMORY
button. The maximum temperature reading achieved will be displayed in the top display (“MAX” will appear to the right
of the value). The minimum temperature reading achieved will be displayed in the middle display (“MIN” will appear to
the right of the value). Press the TEMP MEMORY button a second time, within 5 seconds, to return the current
temperature reading and time-of-day display.
Note:
Five (5) seconds after pressing the TEMP MEMORY button, the unit automatically returns to the current
temperature/time-of-day display.
