| The
HygroClip S probe used with the FH transmitter can be calibrated
and adjusted at one or more points with the HW3 software after
connecting the probe to a PC with the MOK-03-WIN cable (see
accessories): |

HW3
Software: software based probe calibration
is both simple and precise: there are no hard-to-reach, hard-to-adjust
potentiometers. HW3 offers a high level of flexibility in selecting
the calibration reference, giving the user complete control
over the calibration process. HW3 features the following calibration
modes:
• Humidity: 2, 3 or 4 points
• Temperature: 2 points
• 1-point adjustment function (offset) for both humidity and
temperature
When humidity calibration is done using the Rotronic humidity
standards, HW3 automatically corrects the value of the standard
to reflect the temperature of calibration (see note). HW3 also
offers the possibility of printing a certificate of calibration.
Note:
the value of the standards does not depend on barometric pressure
(altitude). |

Certified Humidity Standards: if you do not have access
to a humidity generator, the Rotronic humidity standards offer
a reliable and convenient way to generate a reference humidity
condition during probe calibration. The Rotronic standards are
shipped with an internationally accepted certificate, meeting
in full the requirements of quality systems such as ISO 9000.
The standards are available in boxes of 5 glass ampoules of
the same value, and can be stored indefinitely. Standards in
the range of 5 to 95 %RH are non-saturated aqueous salt solutions.
The 0 %RH humidity standard is made of small granules of a highly
porous ceramic. A Material Safety Data Sheet is available for
each standard. |

Calibration Devices: the ER-15 calibration
device is a small airtight container that fits on the HygroClip
S probe and seals around the humidity sensor. During calibration,
a known reference humidity is produced inside the calibration
device by means of a humidity standard. |
