Product Overview

Vaisala HUMICAPâ Humidity 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 (T

d

) 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.

Wall Assembly Dimensions

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 I

out

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 I

out

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

I

out

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 I

out

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 HUMICAPâ Feuchte- 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.
