    This allows technicians to perform calibrations in the laboratory, workshop or on-site. The HygroGen2 uses a mixed flow method for generating the %rh required by the user. A desiccant cell provides a source of low humidity and a piezoelectric humidifier generates high humidity. A Peltier element is used for heating and cooling the chamber.

    The IP address assigned to your instrument will be reported in the Network Settings interface and via the “HygroGen2 Info” screen. The HygroGen2 will assign itself a network name/identity. This can be changed within the interface. It is recommended to change it to the instrument’s serial number, though local network policies may require something else.

    5.1.1 Water in the Chamber Before using the HygroGen2, check that there is no visible water inside the chamber. If the last condition run by the HygroGen2 was at high humidity and the unit not correctly shut down (see below), condensation may have formed.

  • Page 48: Above Ambient Temperature Operation

    The immersion depth of any probe inserted in the HygroGen2 should be within the limits of 100-150mm (4-6”), measured from the inner side of the door. This will reduce the effect of room temperature via stem conduction on the probe.

    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.

  • Page 50: Switching Off The Hygrogen2

    In normal circumstances use “Shutdown”. This dries the chamber to prevent residual water and isolates the humidifier from the chamber. Once correctly shutdown, the HygroGen2 is in a suitable condition for short- to medium-term periods without use. It is also put into a condition where it can be moved carefully in a horizontal position (e.g.
  • Page 51 Document title Transit Use “Transit” to shut down and condition the HygroGen2 if the unit is to be transported or stored for an extended period. The HygroGen2 will ask for the unit to be emptied of water. It will isolate the humidifier from the chamber and then cool/dry the chamber to ensure excess water is removed.

  • Page 52: Preparing The Unit For Transit Or Storage

    Shut down the HygroGen2 according to the Transit Shutdown Procedure above. If the HygroGen2 needs to be shipped, always use the original double-layer cardboard packaging. The HG-TB transit bag is suitable for hand carrying only; for air or truck shipping, supplement the HG-TB with a sturdy cardboard box with at least 100mm of foam or other shock protection material surrounding all sides.

    HygroGen2 on the lowest RH set-point (5%rh) for at least 15 minutes. Changing Desiccant Remove the desiccant cell from the HygroGen2 by pulling firmly on the cell cap (Figure 1(5)). The cell is held in place securely to maintain an air-tight seal; a gentle twist will help removal. Changing the desiccant should be undertaken in a ventilated area.
  • Page 57 Caution: Do not use dusty desiccants as the dust may be passed into the chamber. Choice of Desiccant The HygroGen2 is supplied from the factory filled with molecular sieve desiccant. Molecular sieve is preferred due to its higher performance in all temperature and humidity conditions and is longer lasting and can be regenerated through heating.

    Some humidity instruments are used in environments where chemical contaminants may be present. Should these transfer to the HygroGen2, this may result in drift of the RH control probe, which would become apparent during calibration.
