Product Overview
Vaisala HUMICAPâHumidity and Temperature Transmitter Series HMT130 measures relative
humidity (RH) and temperature (T) and outputs the measurements to voltage outputs and
RS-485. Other quantities, such as dewpoint (Td), can be calculated from the basic RH and T
values according to the device configuration.
HMT130 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.
The transmitter can also be ordered with an optional LCD display without backlight.
HMT130 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.

Duct Installation Kit
A = Probe (HMP110)
B = Duct installation kit
C = Probe Cable
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 Uout voltage 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 Uout voltage 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).
