7.7 SETTINGS
Definition
This function is used to do the following:
• turn the trend indicators on or off
• change the symbol used for relative humidity
Procedure
Trend
: use the UP or the DOWN key to enable or disable the trend indicators.
The trend of humidity and temperature is shown on the display by an arrow (up or down) to the left
of the measured value. Both arrows are shown to indicate stable conditions. Stable conditions are
defined as rate of change of less than 0.02 %RH / min or °C / min.
Signal stability is first evaluated after 60 seconds into the measurement and is updated every 30
seconds.
HygroFlex 2 and 3: when the trend indicator is enabled, the symbol for the calculated parameter
(e.g. Dp for dew point) is no longer displayed to the left of the numerical value.
