The Humilab Relative Humidity Generator is designed to perform
U.S. National Institute of Standards and Technology (N.I.S.T.) trace-
able calibration of RH instruments and/or several smaller transmit-
ters.
The Humilab design is based on the proven divided flow tech-
nology. Divided flow in the time domain excels as a reliable
method for accurately controlling relative humidity at a fixed
temperature. Temperature stability is ensured by a water jacket
surrounding the calibration chamber.
Continuous digital control, using a built-in GE General Eastern
N.I.S.T. traceable chilled mirror dew point hygrometer, makes the
Humilab a traceable relative humidity transfer standard with which
to calibrate other devices. Calibrations meeting the requirements of
ANSI Z540-l-1994, MIL-STD 45662A, 10CFR-50, and ISO 9001 may
be performed.
The included Prostep software allows you to use your PC to upload
a control profile via the RS-232 port, enabling an entire calibration
cycle to be run.
This manual provides the information you will need to set up, use,
and maintain the Humilab Relative Humidity Generator. Please
read and follow these instructions carefully to ensure that the
instrument provides the precise and reliable humidity measure-
ment and control that you have come to expect from GE General
Eastern.
Four categories of information are presented with an accompa-
nying icon for quick identification.
The exclamation mark within a triangle indicates that the accom-
panying information is important to the correct operation of the
equipment. You should take particular care to observe this informa-
tion because it ensures optimum operation and avoids potential
damage to the unit.
