5.1.5 Protective filters
Make sure you allow appropriate extra time for probes with particular protective filters. These probes
require longer time than the HygroGen2 to stabilise.
The Trend Screen displays the measured values over time (10 minute default on the x axis), so the user
is able to observe whether the HygroGen2 is stable within the acceptance criteria.
5.1.6 Low Water Level Alarm
The unit will inform the operator if the water level in the reservoir is too low with a visual “Low Water
Level” prompt on the controller screen. This prompt may be dismissed by following the on-screen
instructions.
If the water level in the saturator falls below 20ml, humidification is disabled to prevent damage to the
humidifier. Humidification will not be re-activated until the water level is restored.
Replenish the reservoir according to the instructions in section 2.4 .
Note: If the “Low Water Level” message appears on the controller screen during use, the HygroGen2
can be topped up with 50ml of distilled water. This will bring the total water content of the reservoir to
approximately 80ml.
5.1.7 Water Level Indicator Calibration
The water level sensor may behave differently for different qualities of water. To ensure accuracy of
the water level indicator, period calibration is advised. To access this feature, go to the Settings Screen
and select “Water Level” from the “Settings” drop-down menu. Follow the on-screen instructions.
