HD SERIES INSTALLATION GUIDE
PRODUCT OVERVIEW
The HD Series duct-mounted humidity sensors provide high accuracy humidity
monitoring with a fully replaceable HS element for easy field maintenance. NIST
certified accuracy and temperature sensing capability are available. The HD is
warranted for a period of five years.
TROUBLESHOOTING
Problem Solution
Filter tip does not fit on probe HS element is backwards; reverse element.
Unit reads approx. 4.5mA HS element is backwards; reverse element.
Unit reads 100% with new
replacement sensor
Unit must be unpowered when installing a new sensor;
interrupt sensor power to restart.
Accuracy appears incorrect · Remove HS element while powered and verify output
goes to full scale.
· Verify voltage test leads on 4-20mA models
corresponds to the 4-20mA output.
