2.5.4 Trimmers
Figure 5 Component Board Adjustment
Trimmer
1 Use a Phillips head screwdriver (PH0)
to rotate the RH or T adjustment
trimmer. To increase the measurement
output value, rotate the trimmer
clockwise. To decrease, rotate
counterclockwise.
Note that there is a slight delay before
the measurement output changes
after rotating the trimmer.
You can adjust the transmitter's RH or T measurement output with the trimmers on the
component board. During trimmer adjustment, the output of the transmitter is corrected using
the trimmers until the output matches the known value of a reference.
Figure 6 RH and T Trimmer Adjustment Ranges (Indicative)
You can only calibrate the relative humidity measurement (RH) and temperature
measurement (T). Other parameters (available for HMD62) are calculated
internally based on RH and T. Check that the output selection DIP switch is set to
RH when making adjustments with the physical trimmer; when using the Insight
PC software, set all DIP switches to the OFF position.
CAUTION!
restore the factory settings, always return the physical trimmer to the middle
position before starting. When you make an adjustment with Insight, the
10
position in which the trimmer is at that point is set as the ±0 point.

You can change the humidity parameter that is output on the RH channel of HMD65 with the
DIP switches on the component board. Select the parameter you want the transmitter to
output by sliding the parameter's DIP switch to the right (ON). In the example in Figure 7
(page 11), the selected output parameter is dew point/frost point temperature (Tdf). Keep the
other DIP switches in the OFF position (left).
The selected parameter uses the default scaling shown in Table 4 (page 11).

CAUTION!
Note that the humidity output parameter selected with the DIP
switches on the transmitter component board will be used instead of the
parameter selected with Insight. When using Insight to configure the output, set
all humidity parameter selection DIP switches on the transmitter component
board to the OFF position (left) to ensure they do not cause a conflict with the
Insight settings.

Page 14
HMD65 User Guide M212243EN-A
If you use Insight to set both analog output channels to output T measurement,
the humidity parameter DIP switches do not have an eect on the output.
2.6 Filtering Factor
If the measuring environment produces occasional exceptionally high or low readings that
need to be averaged out in the output, you can apply a filtering factor to the RH or T output
(filtering factor range: 0.001 … 1.000). The filtering factor defines the speed at which the latest
measurement is integrated into the transmitter's output. By default, the filtering factor is set to
0.500, which means that the displayed output is a 50%+50% combination of the previous
measurement and the most recent measurement. To show the latest measurement directly in
the output, set the filtering factor to 1.000 (no filtering).
The following formula is used when calculating the output:
output = [(new (unfiltered) measurement × filtering factor) + (previous output × (1.0 - filtering
factor))]
The filtering factor can be configured with the Insight PC software.
More Information

Setting Filtering Factor with Insight (page 25)
2.7
Environmental Compensation
By default, the pressure value used in HMD65 measurement calculation is 1013.2 hPa. If the
pressure of your measurement environment diers from this, you can configure the
transmitter's pressure compensation value with the Insight PC software.

3.2 Duct Mounting Overview
Figure 9 Duct Installation Overview
Make sure there is a minimum clearance of 5 m (16.5 ft) between the probe body and any
1
possible humidifier. Avoid installing in a location where condensation can fall on the
sensor inside the duct.
2 When installing the transmitter, drill a second hole approximately 30 cm (12 in) from the
installation hole, towards the direction of the air flow, and plug it with a removable seal.
This second hole is intended for later use in reference measurement with another device
when calibrating or adjusting the transmitter.
3 Check that the duct diameter is suitable for the probe body (see Transmitter Dimensions
(page 13)). Ideally, the sensor (probe head) should be installed in the middle of the duct.
4 Maximum air flow speed: 50 m/s (with sintered filter).
5 Avoid installing the transmitter in dead legs. Supersaturation can occur in areas where
there is no air flow.
6 Do not install the probe in a downward angle. Condensation can travel to the sensor along
the probe body if the probe points down.
7 Install the probe in a 90° angle so that the sensor is placed as close to the middle of the
duct as possible.

The BACnet MS/TP MAC address range for the transmitter is 0 … 127 (master mode only).
The Modbus RTU MAC address range for the transmitter is 1 … 247.
Configuring an address above the range maximum results in the address defaulting back to
the maximum address (127 or 247). Addresses below the range minimum default to the
minimum address (0 or 1).
Bit Rate and Parity Options
• The bit rate 4800 is used only for Modbus RTU (use 9600 and above for BACnet MS/TP).
• If the bit rate DIP switches are all set to OFF (left), the following defaults are used:
• Modbus RTU: 19200
• BACnet MS/TP: 38400
• The parity selection (N/E) only has an eect on Modbus RTU communication.

7. Calibration and Adjustment
7.1 Calibration and Adjustment Overview
You can calibrate or adjust the transmitter's measurement output using one of the following
options:
• 1-point adjustment with the RH and T trimmers on the HMD60 component board
(adjustment range: -5%RH … +5 %RH and -0.3 °C … +0.3 °C (-0.54 °F … +0.54 °F).
• 1-point or 2-point adjustment by connecting the transmitter to Vaisala Insight PC software
(requires USB cable 219690).
• 1-point adjustment by connecting the transmitter to an MI70 hand-held indicator (requires
MI70 connection cable 219980SP).
7.2 Calibration and Adjustment Using Trimmers
HMD60 transmitters have 2 separate trimmers for RH and T measurement output adjustment
mounted on the component board. The trimmers allow for easy 1-point adjustment of the
measurement output against a reference with a known value.
The transmitters are shipped with the trimmers centered. Turning the trimmer counterclockwise decreases the measurement output value, and turning clockwise increases the value.
Figure 25 (page 34) shows the trimmer adjustment ranges for RH and T (-5 %RH … +5 %RH
and -0.3 °C … +0.3 °C (-0.54 °F … +0.54 °F).

Appendix B. BACnet Reference
This appendix describes the BACnet protocol implementation of the HMD65 relative humidity
and temperature transmitter.
Implementation
The BACnet standard has many options for both physical and data link layers. HMD65
implements the following communication options:
• MS/TP Master
MS/TP Master
Master mode operation means that the HMD65 transmitter is part of a token passing loop.
Master can send messages to the MS/TP bus when it has received a token. According to
BACnet standard, the master address must be in the range 0 … 127. For correct operation,
Master mode also requires that the parameter MAX_MASTER is set. It must be same in every
master node connected to the same bus segment. MAX_MASTER defines highest MAC address
used by master nodes. For instructions on configuring the MAX_MASTER parameter with
Vaisala Insight PC software, see Configuring BACnet with Insight (page 28).
Master functionality enables automatic network setup. The client can send inquiries such as
“who has property XYZ” or “who is device number 12345”. The device replies to inquiries when
it is available to talk. When the master mode device has no token it behaves as a slave, that is,
it replies to requests.
MAC Address
The MS/TP address for MS/TP master is 0 … 127. The address is selected by DIP switches: see
Modbus and BACnet Overview (page 26).
Communication Parameters
The fixed serial line parameters are: No parity, 8 Databits and 1 Stop bit.
The communication speed is selected by DIP switches. The supported communication speeds
are 9600, 19200, 38400, 57600, 76800 and 115200.
If DIP switches are set to select 4800 bps, 38400 is used instead. 4800 bps is not a supported
BACnet baud rate.
Physical Interface
The physical interface for using HMD65 through BACnet is galvanic isolated RS-485. There are
weak pull-up and pull-down resistors (100k) from data lines to +3.3VDC and GND. A
termination resistor (120 ohm) can be connected between data lines with a DIP switch on the
HMD65 component board. Three screw terminals are needed: D+ (485+), D- (485-) and GND
(RS485_GND). For DIP switch and screw terminal locations, see Figure 18 (page 26).
54
Page 57
Appendix B – BACnet Reference
Configuration
There are several settable parameters for BACnet communication. Some parameters must be
set correct before device is connected to the BACnet network. The initial BACnet configuration
of the device is selected when ordering the device, and can be configured using Vaisala Insight
PC software, DIP switches, or BACnet protocol. Table 18 (page 55) lists the configuration
options.

Limited functionality. Due to inaccurate internal clock, does not support
Device communication control with finite duration.
Latest_sent_value is initialized on startup. If dierence between the

COV_INCREMENT, then US-COV is sent and latest_sent_value set to the
sampled value.

Data persistence
Persistence of writable parameter values in BACnet devices is largely a local matter.
Nonvolatile parameters are saved in device Flash memory. Volatile parameters are always
initialized to some default value at startup. This is defined in each property definition in this
appendix. Saving takes eect during the Write Property function.
