Product Overview
Vaisala HUMICAPâHumidity and Temperature Transmitter Series HMT120 measures relative
humidity (RH) and temperature (T) and outputs the measurements to analog current loop
outputs. Other quantities, such as dewpoint (Td) can be calculated from the basic RH and T
values according to the device configuration.
HMT120 is available either with a fixed probe directly attached to the transmitter housing, or
with a remote probe with dierent (3/5/10/20m) cable lengths.
HMT120 can also be ordered with an optional LCD display without backlight.
HMT120 is typically installed mounted on the wall with up to four screws (not included). Rain
and radiation shields and a duct installation kit are available as accessories. A drilling template
is available at the end of this guide to help you position the screws correctly.

It is possible to damage the display when tightening the screws, as
there is not much room between the upper fastening holes and the exposed
display component. Be particularly careful when using a cordless drill.

1. Pass the probe cable through the plastic pipe of the duct installation kit.
2. Connect the probe cable to the HMP110.
3. Use a 24mm drill bit to make a hole in the duct wall.
4. Use a 3.2mm drill bit to make four holes for the installation screws
(ST4.2x16-C-Z DIN7981 screw, 4pcs). The holes should be arranged
in a square around the 24mm hole, at a distance of 42mm from each other.
5. Mount the probe holder using the screws (D).
6. Adjust the depth of the plastic pipe and tighten the screw (E) to lock the probe in place.

Adjusting Humidity and Temperature with
Push Buttons
The instructions here apply to both 1-point and 2-point calibration.
To make a humidity or temperature adjustment:
1. Open the transmitter cover. There are 3 buttons marked ADJ, +and -on the motherboard.
There are also two indicator LEDs, one green and one red.
2. Press the ADJ button and hold it down until the green indicator LED begins to blink slowly
(800ms cycle time).
3. The transmitter is now in RH calibration state. Analog output and optional display will still
follow the actual measured RH value.
If you do not wish to perform the RH adjustment at this time, press the ADJ
button one more time. The green indicator LED turns o and the red
indicator LED begins to blink slowly (800ms cycle time) to indicate T
calibration state. To calibrate T, follow the instructions starting from step 7.
4. Remove the filter and insert the probe into a measurement hole of the dry end reference
chamber (for example, LiCl: 11 % RH) to do the low humidity oset adjustment.
Do not touch the adjustment buttons before the conditions have stabilized.
This takes approximately 30 minutes.
5. Press either the -or +button at least once, make sure that the Iout current is correct,
adjust using the -and +buttons if needed, and press the ADJ button again. The green
indicator LED begins to blink faster (400ms cycle time).
If you do not wish to perform the two-point RH adjustment at this time, press
the ADJ button one more time. The green indicator LED turns o and the red
indicator LED begins to blink slowly (800ms cycle time) to indicate T
calibration state. To calibrate T, follow the instructions starting from step 7.
If one-point calibration is done at more than 50% RH, a gain adjustment is
done instead of an oset adjustment.
6. Insert the probe into the high end reference chamber (for example, NaCl: 75 % RH
chamber in the humidity calibrator HMK15) and do the high humidity gain adjustment by
using the - and + buttons to make sure the Iout current is correct (you have to press either
-or +at least once even if the value is correct). To finish the RH calibration, press the ADJ
button. The green LED is now turned o and the red indicator LED begins to blink slowly
(800ms cycle time).
10 M211247EN-E

7. The transmitter is now in T calibration state. Analog output and optional display will still
follow the actual measured T value.
If you do not wish to perform the T adjustment at this time, press ADJ button
one more time. The red indicator LED is turned o and the transmitter
returns to normal mode. The calibration procedure is now finished.
8. Insert the probe into a known reference temperature (if Vaisala Humidity Calibrator
HMK15 is not used) and let the temperature reading stabilize.
Do not touch the adjustment buttons before the conditions have stabilized.
9. Using the -and +buttons, make the temperature oset adjustment by making sure the
Iout current is correct (you have to press either -or +at least once even if the value is
correct) and press the ADJ button. The red indicator LED begins to blink faster (400ms
cycle time).
If you do not wish to perform the two-point T adjustment at this time, press
the ADJ button one more time. The red indicator LED is turned o and the
transmitter returns to normal mode. The calibration procedure is now
finished.
10. Insert the probe into another reference temperature.
Do not touch the adjustment buttons before the conditions have stabilized.
11. Using the -and +buttons, make the temperature gain adjustment by making sure the Iout
current is correct (you have to press either -or +at least once even if the value is correct).
12. Press the ADJ button one more time. The red indicator LED turns o and the transmitter
returns to normal mode. The calibration procedure is now finished.
In case of calibration error, both LEDs blink alternately at a very fast rate (cycle
time 200ms) for a period of 2s after which the transmitter returns to normal
mode.

ENGLISH

If your transmitter has the optional display, the following notifications are shown
on the display during calibration:
•Probe cal: RH 1 (corresponding the green LED blinking slowly)
•Probe cal: RH 2 (corresponding the green LED blinking fast)
•Probe cal: T1 (corresponding the red LED blinking slowly)
•Probe cal: T2 (corresponding the red LED blinking fast)
•Probe cal: Error (corresponding both LEDs blinking alternately at very fast
rate)

Produktübersicht
Der Vaisala HUMICAPâFeuchte- und Temperaturmesswertgeber der Serie HMT120 misst die
relative Luftfeuchte und/oder die Temperatur und wandelt die Messwerte in analoge
Stromschleifenausgänge um. Andere Größen wie der Taupunkt (Td) können je nach
Gerätekonfiguration über die Basiswerte für rF und T berechnet werden.
Der HMT120 ist wahlweise mit einer direkt am Messwertgebergehäuse befestigten Sonde oder
mit einer dezentralen Sonde mit unterschiedlichen Kabellängen (3/5/10/20 m) erhältlich.
Für den HMT120 steht auch eine optionale LCD-Anzeige ohne Hintergrundbeleuchtung zur
Verfügung.
Der HMT120 wird in der Regel mit bis zu vier Schrauben (nicht im Lieferumfang enthalten) an
der Wand montiert. Ein Regen- und Strahlungsschutzgehäuse und ein Kanalinstallationssatz
sind als Zubehör erhältlich. Die Bohrschablone auf der hinteren Umschlaginnenseite dieses
Handbuchs hilft Ihnen bei der korrekten Positionierung der Schrauben.
