AFTER MONITORING FOR 199 DAYS, THE METER WILL NEED TO BE RESET
BY DEPRESSING THE “+” AND “-” BUTTONS AT THE SAME TIME. THIS
WILL RESET THE “DAYS” AND “HOURS” DISPLAY TO 0, BUT WILL NOT
CHANGE THE PREVIOUSLY SELECTED “ALERT” SETTINGS.
Removing the batteries clears all stored data and clock settings.
Default Settings
*Relative Humidity (RH%): 60%
*Temperature: °F
*Hours: 12 hours (not displayed but automatically programmed)
*Days/Hours: 0

Each function will be displayed automatically through a continuous rotation cycle.
If you turn the meter off, all settings will remain in place. Alarm will not sound.
At default settings, if RH exceeds 60% for 12 continuous hours, alarm will sound
for 5 seconds. This will repeat every 30 minutes until you shut off the alarm or
the battery dies. The Humidity Alert™ will tally hours of RH over 60%.
For Advanced Programming
After the “%RH” and “hours” are set, the meter tracks and displays the number
of days from 0 to 199, and the accumulating hours the %RH exceeded the set
point.
5

When the RH and hours are exceeded, the alarm will sound for 5 seconds
and then every 30 minutes, regardless of the current %RH. The meter
continues to monitor conditions, accumulating the total hours of continuous
high humidity at the set point. If the moisture level falls below the set point,
the accumulation of hours stops until the %RH again exceeds the set point.
Hours begin again at zero.
6

For example: Assume you have selected 60%RH and 12 hours for your set
points. The alarm is activated after humidity exceeds 60% for 12 continuous
hours. The continuous hours are tracked and displayed until the humidity falls
below the alarm level (60%RH). If the RH falls below 60%, the hour count stops.
If the humidity exceeds the set point again for a period of 12 continuous house,
the total hours of continuous high humidity are added to the previous 12 hours
to total 24.

De-Activating the Alarm
To stop the alarm, press either the “+,– “ or “Set” buttons.
Resetting the Alarm

from 0 while retaining the previous accumulated days and hours of high humidity
set point information.
