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.

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.
