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.
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.

Disconnect power to the unit.1.
Remove probe from junction box by loosening black swage nut and sliding out.2.
For 4–20 mA versions: Test leads output 0-1VDC corresponding to 0 to 100% RH
sensor reading. For example, a 0.42 VDC output on test points equals 42% RH sensor
reading. These test points also provide an output that verifies mother board accuracy
when the HS element is removed. CONNECT TEST POINT LEADS TO VOLTMETER ONLY.
This output is not suitable for connection to a DDC panel.
To check motherboard accuracy using the test leads, remove sensor element. 1.0 VDC
reading verifies motherboard accuracy.
To verify sensor accuracy, de-power unit and insert a replacement HS element.
Repower unit and compare readings to original sensor. For example, if test points
read 0.40VDC (40% RH) with original sensor, and 0.45VDC (45% RH) with new
replacement sensor, the original sensor is 5% off specification. This method of
ensuring accuracy offers more precision than using slings or other devices, and it
eliminates the need to manually adjust sensors to an unstable standard.
Note: Temperature, body sweat, and breath effect humidity. Ensure that conditions
are stable to evaluate performance.
Filter may be washed using warm water and soft brush. Do not attempt to scrub HS
element.
For 0-5V/0-10V versions, use output as test point and scale accordingly.
