ELECTRONIC HUMIDITY
TRANSMITTER: H100
DESCRIPTION
The H100 series low voltage, microcomputer-based PI
(proportional and integral) humidity transmitters are
designed for accurate humidity and/or dehumidification
control in non-corrosive commercial applications such
as: hospitals, schools, office buildings, retail stores,
museums, computer rooms, etc.
The H100 series is available with 0 to 5 Vdc or 10 Vdc
output signal.
Each transmitter is computer calibrated and factory
programmed with default parameters.

CALIBRATION OF TRANSMITTER
The transmitter is factory calibrated. However, it can be field recalibrated by using the ( -10%, 0%, +10% )
potentiometer inside the transmitter to adjust the zero (see page 2 for location). The transmitter is already factory
calibrated to the center of the potentiometer. To recalibrate the transmitter to the factory preset, return the
potentiometer to the 0% adjustment.
To calibrate, read the humidity with a precision hygrometer. If the reading is lower than the value you get from the
sensor, remove transmitter from the base, turn the potentiometer by the amount of error in the negative scale. If the
value is higher, turn the potentiometer in the positive scale. We recommend that you don’t try to adjust the two
potentiometers on the sensor unless you have access to two points of calibration. If you really need to recalibrate the
sensor, please return the transmitter to the factory.
