5.2.1 Setting Calibrated Humidity
The console allows you to calibrate both the indoor and outdoor humidity. To calibrate humidity, you will
need an accurate source such as a sling psychrometer or Humidipaks One Step Calibration kit.
To calibrate indoor humidity, in the Set Mode with indoor humidity flashing, press the + key or MIN/MAX
key to increase or decrease the humidity setting (in increments of 1%) to match the calibrated or known
humidity source. To return the indoor humidity to the measured value, press and hold the SET key for 3
seconds and the humidity will return to the uncalibrated value.
To calibrate outdoor humidity, in the Set Mode with outdoor humidity flashing, press the + key or
MIN/MAX key to increase or decrease the humidity setting (in increments of 1%) to match the calibrated
or known humidity source. To return the outdoor humidity to the measured value, press and hold the SET
key for 3 seconds and the humidity will return to the uncalibrated value.
Note: The remote (outdoor) thermo-hygrometer will always display the measured humidity level and not
the calibrated humidity level. Only the console will show the calibrated value.
Note: The dew point calculation is based on the calibrated humidity level.
5.2.2 Setting Barometric Pressure
The display console displays two different pressures: absolute (measured) and relative (corrected to
sea-level).
To compare pressure conditions from one location to another, meteorologists correct pressure to
sea-level conditions. Because the air pressure decreases as you rise in altitude, the sea-level corrected
pressure (the pressure your location would be at if located at sea-level) is generally higher than your
measured pressure.
To determine the relative pressure for your location, locate an official reporting station near you (the
internet is the best source for real time barometer conditions, such as Weather.com or
Wunderground.com), and set your weather station to match the official reporting station.
To change the relative pressure, when pressure is flashing when in Setting Mode press the + key or
MIN/MAX key to increase or decrease the relative pressure setting to match the official reporting station.
5.3 Alarm Mode
While in Normal Mode press the ALARM key to enter the High Alarm Mode.
Press the ALARM key again to enter Low Alarm mode.
Note: after the initial pressing of the ALARM key, the display will be refreshed to show the
current high and low alarm value. The normal alarm value will be displayed only for those already
activated, all other non activated values will be displayed with "---".
Press the ALARM key again to return to Normal Mode.
In the High Alarm Mode press the SET key to select the following alarms:
1.
Time alarm (hour/minute)
2.
Indoor humidity high alarm
3.
Indoor temperature high alarm
4.
Outdoor humidity high alarm
5.
Outdoor temperature and dew point high alarm
6.
Pressure high alarm
In the Low Alarm Mode press the SET key to select the following alarms:
1. Time alarm (hour/minute)
2. Indoor humidity low alarm
3. Indoor temperature low alarm
4. Outdoor humidity low alarm
5. Outdoor temperature and dew point low alarm
6. Pressure low alarm
In the alarm modes press the + key or MIN/MAX key to change or scroll the alarm value. Hold the +
key or MIN/MAX key for 3 seconds to change the number faster. Press the ALARM key to choose
