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 (HMD62) or T (HMD62 and TMD62) 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
10
position before starting. When you make an adjustment with Insight, the 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 HMD62 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 transmitter's 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 5 (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.

HMD62 TMD62 User Guide M212016EN-B
HMD62 only:If you use Insight to set both analog output channels to output T measurement, the humidity parameter DIP switches do not have an eect 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 34)

 Environmental Compensation (HMD62)

By default, the pressure value used in HMD62 measurement calculation is 1013.2 hPa. If the pressure of your measurement environment diers 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.

4. Calibration and Adjustment

4.1 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).

4.2 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 12 (page 18) 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).
Figure 12 RH and T Adjustment Trimmer Ranges (Indicative)
The trimmers will only turn 135 degrees each way, less than half a rotation. Do not force the trimmer past the stopping point.

Page 21
Chapter 4 – Calibration and Adjustment
CAUTION!
restore the factory settings, always return the physical trimmer to the middle position before starting. When you make an adjustment with Insight, the position in which the trimmer is at that point is set as the ±0 point.
If you use the Insight PC software to adjust the measurement or to

4.2.1 1-Point Adjustment Using Trimmers and Reference Calibrator

• Reference environment(s) for producing the desired humidity and/or temperature (for example, Vaisala HMK15 Humidity Calibrator).
• A multimeter for checking the analog output reading (connect in series to measure the current output).
• Small Phillips head screwdriver for turning the trimmers.
To adjust the output:
1. Prepare the reference (for example, a humidity calibrator). Use a reference that matches your normal measurement environment as closely as possible.
2. Connect the multimeter to the analog output (connect in series to measure the current output).
3. Insert the probe head in the reference environment.
4. Wait for the reference measurement to stabilize fully. This may take more than 30 minutes. Monitor the readings to see when the measurement has stabilized.
5. When the measurement has stabilized, adjust the output with the trimmers until it matches the known value of the reference.
Note that there is a small delay before the output value updates after you turn the trimmer.

4.2.2 Adjusting Output Using Trimmers and Reference Transmitter (1-point adjustment)

• A recently calibrated reference device (for example, a second HMD60 transmitter).
• A multimeter for checking the analog output reading (connect in series to measure the current output).
• Small Phillips head screwdriver for turning the trimmers.
19
Page 22
HMD62 TMD62 User Guide M212016EN-B
It is assumed that a hole was drilled for the reference instrument during installation, the transmitter is powered, and you can view the measurement output value.
To adjust the output:
1. Insert the reference transmitter into the measurement environment next to the transmitter that you are adjusting. The reference transmitter should be inserted approximately 30 cm (12 in) from the HMD60 probe's installation hole, towards the direction of the air flow. See Figure 9 (page 14).
2. Connect a multimeter to the analog output of the reference transmitter (connect in series to measure the current output).
3. Wait for the measurement to stabilize fully. This may take more than 30 minutes. Monitor the readings to see when the measurement has stabilized.
4. When the measurement has stabilized, adjust the output of your transmitter with the trimmers until it matches the output of the reference transmitter.
Note that there is a small delay before the output value updates after turning the trimmer.
5. When done, plug the installation hole of the reference transmitter.

4.2.3 Resetting Trimmers Back to Zero
