5.2 Setting Mode Continued:
14) Relative pressure setting from 700hPa – 1100hPa (default 1013.5hPa). Press
the
SET
key to adjust the relative barometric pressure. Press the
+
key or
MIN/MAX
key to adjust the relative barometric pressure up or down.
Please see Setting Barometric Pressure notes
below for further
information.
15) Pressure threshold setting (default 2hPa). Press the
SET
key again to adjust
the pressure threshold setting. Press the
+
key or
MIN/MAX
key to adjust
the pressure threshold up or down.
16) Storm threshold setting (default 4hPa).Press the
SET
key again to adjust the
storm threshold setting. Press the
+
key or
MIN/MAX
key to adjust the
storm threshold up or down.
Note:
Please set the units firstly before change units’ value. When changing the
unit setting, the value will convert accordingly but may cause resolution loss due
to the internal calculation-algorithm.
5.3 Setting Calibrated Humidity:
The display console allows you to calibrate both the indoor and outdoor
humidity. Humidity is a difficult parameter to measure accurately and drifts over
time - the calibration feature allows you to compensate for this. To calibrate
humidity, you will need an accurate source, such as a sling psychrometer or
whirling hygrometer.
To calibrate indoor humidity - In the Setup Mode with the indoor humidity
flashing, press the
+
key or the
MIN/MAX
key to increase or decrease the
humidity setting (in increments of 1%) to match the 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 Setup Mode with the outdoor humidity
flashing, press the
+
key or
MIN/MAX
key to increase or decrease the humidity
setting (in increments of 1%) to match the 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 thermo-hygrometer will always display the measured
humidity level and not the calibrated humidity level. Only the console will show
this calibrated value.
Note:
The dew point calculation is based on the calibrated humidity level.
