2.7 ESD protection
Electrostatic discharge (ESD) can damage electronic circuits. Vaisala products are adequately
protected against ESD for their intended use. However, it is possible to damage the product by
delivering electrostatic discharges when touching, removing, or inserting any objects in the
equipment housing.
To avoid delivering high static voltages to the product:
• Handle ESD‑sensitive components on a properly grounded and protected ESD workbench
or by grounding yourself to the equipment chassis with a wrist strap and a resistive
connection cord.
• If you are unable to take either precaution, touch a conductive part of the equipment
chassis with your other hand before touching ESD‑sensitive components.
• Hold component boards by the edges and avoid touching component contacts.

Chapter 3 – Functional description
3. Functional description
3.1 DRYCAP® technology
Vaisala DRYCAPâ dew point measurement technology ensures accurate measurement with
excellent long term stability. Its unrivalled performance is based on two innovations: the
proven capacitive thin-film polymer sensor and the self-diagnostic functions that the software
performs automatically as needed.
The sensor’s thin-film polymer absorbs or releases water vapor as the surrounding humidity
increases or decreases. The dielectric properties of the polymer change as the humidity
around the sensor changes, as does the capacitance of the sensor. Capacitance is converted
into a humidity reading. The capacitive polymer sensor is bonded together with a temperature
sensor, and dew point is calculated from the humidity and temperature readings.
The automatic sensor functions are called autocalibration, sensor purge, and sensor warming.
They are a key element in achieving the stability, rapid response time, and condensation
resistance of the DRYCAPâ sensors.
3.2
Autocalibration
Autocalibration of the DRYCAP sensor optimizes measurement stability in dry environments.
During autocalibration the sensor is warmed for a short period (< 1 min) and the sensor
capacitance values are evaluated at the elevated temperature. The possible dry end drift is
then corrected to correspond to the calibrated values. During autocalibration the values of all
available output parameters are locked (showing the latest valid value).
DMP80 series probes perform autocalibration at 1-hour intervals, and whenever sensor purge
is performed. When measuring very dry conditions, the probe performs autocalibration at
shorter intervals. A significant change in dew point or temperature may also trigger
autocalibration.
Autocalibration is carried out only if several criteria for the measurement environment are
fulfilled. This ensures the reliability of the adjustments, and maintains the excellent long term
stability that the patented technology oers. These criteria include, for example, a stable
enough moisture level in the measured atmosphere. If the conditions are not fulfilled, the
autocalibration function is postponed until satisfactory conditions are reached.
Sometimes autocalibration fails to complete successfully due to changes in measurement
conditions. This is normal, and is not a problem as autocalibration will be reattempted
automatically. However, autocalibration should eventually succeed to maintain the accuracy of
the probe.
15
Page 16
DMP80 Series User Guide M212904EN-A
3.3 Sensor purge
Sensor purge is an automatic procedure that minimizes the drift at the wet end readings of the
dew point measurement. The sensor is heated to a high temperature which evaporates all
excess molecules out of the sensor polymer. This, together with autocalibration, results in a
very small drift of the sensor due to the very linear behavior of the polymer technology.
By default, DMP80 probes perform sensor purge when they are powered on (known as startup
purge), and at one day intervals (known as interval purge). If necessary, the purge settings
can be configured with the Insight software or the Indigo80 handheld indicator. However,
Vaisala recommends leaving the sensor purge settings at their default values.
As with autocalibration, during sensor purge the values of the measurement parameters are
frozen at their last measured values prior to the procedure.
3.4 Condensation prevention functions
The sensor warming feature of the condensation prevention function is intended for improving
the condensation tolerance of the probe. It warms the humidity sensor when necessary to
keep the sensor's temperature above the dew point of the measurement environment. When
sensor warming is activated, all temperature-dependent output parameters become
unavailable, unless the temperature compensation setting is set to read the temperature from
an external source. The output parameters become available again 4 minutes after the
warming is stopped.
The humidity limit where sensor warming activates is:
• 80 %RH for DMP80A probes with S sensors
• 70 %RH for DMP80B probes with M sensors
In addition, the DRYCAP® sensor is kept continuously warmed in freezing conditions to ensure
fast response time. Therefore, the temperature and dependent parameters are continuously
unavailable if process temperature is below 0 °C / 32 °F.
3.5
Environmental compensation
Environmental compensations improve the measurement accuracy of the probe. You can
configure the settings with the Insight software or the Indigo80 handheld indicator.
Pressure compensation
The pressure of the measured environment aects the accuracy of humidity calculations,
especially calculations that are dependent on pressure (for example, mixing ratio). To achieve
accurate output of all humidity parameters, you are recommended to update the value of the
pressure compensation setpoint to match the environmental pressure when installing the
probe.
16
Page 17
Chapter 3 – Functional description
For example, when you install the probe in a process with a pressure diering from normal
atmospheric pressure, update the correct pressure into the pressure compensation setpoint
parameter or register of the probe using the Insight software or the Indigo80 handheld
indicator.
The entered value is persistent and remains unchanged at device restart.
Temperature compensation
You need to set an external source for the temperature compensation setpoint if the sensor
warming feature of the condensation prevention function prevents the probe's own
temperature measurement, and the output parameters that require temperature information
to be known are required.
When warming is active, values of output parameters that depend on temperature
measurement (for example, relative humidity) are unavailable, unless temperature information
is read from an external source. Output parameters that can be measured or calculated
without this external temperature information, such as dew point temperature, are available
even without the temperature input.
The external temperature source can be another probe that is connected to the same Indigo80
handheld indicator as your probe.
To get the most accurate measurement values, the external source needs to be able to provide
the temperature compensation setpoint value constantly in real time, and the value needs to
correspond to the temperature of the probe's measurement environment as accurately as
possible. A suitable measurement point is as close to the probe as possible, but yet far enough
so that ongoing condensation prevention warming of the probe does not have an eect on the
measured value.
At device restart, the value is cleared.

‣
Configuring environment settings with Indigo80 handheld indicator (page 26)
3.6
Filtering factor
The filtering factor determines how quickly the results of measurement cycles are reflected in
values of output parameters. You can use the filtering factor to slow down the response time
of the measurement, filtering out rapid changes and measurement noise.
• Maximum value (1) = No filtering, fastest measurement. Output shows 100 % of the most
recent measured value.
• Less than maximum value = Filtering is applied and measurement response time is
reduced. For example, defining a value that is 90 % of the maximum value means that the
filtered output reading = 90 % of the most recent measured value + 10 % of the previous
reading.
Filtering factor settings can be configured with the Insight software or the Indigo80 handheld
indicator.

on the indicator's display, while the probe in the rightmost port is labeled .
5.3
Measurement location
When taking measurements with the probe, consider the following:
• Verify the operating environment specification of the probe model.
• If the temperature of the measured environment diers greatly from ambient
temperature, preferably the entire probe shaft must be inside the measured environment.
This prevents measurement inaccuracy caused by heat conduction along the probe shaft.
• Mount the probe head horizontally to prevent any water condensing on the probe head
from running to the sensors.
Use the optional magnetic hanger accessory (Vaisala item code ASM214318SP) to
attach Indigo80 to a metallic surface when taking measurements.

5.3.1 Configuring environmental compensations
After installation, configure the pressure compensation setting, if relevant to your probe and
its measurement environment.
For example, when you have installed the probe in a process with a pressure diering from
normal atmospheric pressure, update the correct pressure into the pressure compensation
setpoint parameter or register of the probe. This allows the probe to apply the appropriate
pressure compensation into its measurement results.
You can configure the setting with the Insight software or the Indigo80 handheld indicator.

Pressure
Value for pressure compensation. The entered value is persistent and remains
unchanged at device restart.
Temperature
If any value is entered in this field, the device will use it as its temperature
measurement value instead of its own sensor reading. This is needed when sensor
warming is used, as it will also heat the temperature sensor of the device.
At device restart, the value is cleared.
The temperature value needs an external source, for example, another
probe that is able to provide the value constantly in real time, and the
value needs to correspond to the temperature of the measurement
environment as accurately as possible. Thus, set the temperature value
only if you have another probe connected to the indicator from which
you can read the value. Do not set the temperature value manually.

7. Maintenance
7.1 Cleaning the probe
Do not attempt to clean the sensors under the filter.CAUTION!
Do not spray anything directly on the probe head, since that may deposit
impurities on the sensors.
You can clean the probe, probe handle, and cable by wiping them with a soft, lint-free cloth
moistened with water or a suitable cleaning agent, such as isopropyl alcohol. Do not wipe the
filter: wiping the filter may block its pores and/or deposit residue on the filter. If the filter is
heavily contaminated, replace it.
When cleaning, follow these precautions:
• Avoid touching the filter. If you need to touch the filter, always wear clean gloves (cotton,
rubber or similar material). Keep the filter free of any grease or oil.
• Do not scrape the probe or the probe handle, and avoid abrasive cloths when wiping the
surface.
• Do not immerse the probe or the probe handle in liquid to clean them.
• Wipe cleaning agents o the probe, probe handle, and the cable after cleaning.
7.1.1 Chemical tolerance
Avoid exposing the probe to cleaning agents for unnecessarily long periods of
time.
The following chemicals can be used to clean the probe:
• Deionized water
• Isopropyl alcohol (70 %).

• New compatible filter
• Clean lint-free gloves
CAUTION!
the probe head carefully.
1. Put on clean gloves before touching the filter.
2. Turn the filter counter-clockwise to loosen it.
3. Remove the filter from the probe head. Be careful not to touch the sensors with the filter.
4. Install a new filter on the probe head. Tighten the filter properly.
7.3
Calibration and adjustment
Calibration means comparing the measurement output of the device to a known
reference, such as a known environment in a calibration chamber or the output of
a reference instrument. Correcting the reading of the device so that it measures
accurately is referred to as adjustment.
The probe is fully calibrated and adjusted as shipped from the factory. To maintain the
accuracy of the measurement, calibrate and adjust the probe as needed. Typical calibration
interval is one year, but depending on the application it may be necessary to check the
accuracy more frequently.
When adjustment is necessary, have Vaisala calibrate and adjust the probe.
Factory calibration leads to highest accuracy and lowest uncertainty. After factory calibration
the instrument performs as new. For up-to-date information about calibration points and
oering, visit store.vaisala.com.
Sensors are easily damaged when the filter is not in place. Handle
WARNING!
has not been exposed to dangerous contamination, and is safe to handle
without special precautions.

Page 33
If you think the device is not measuring correctly, calibration and adjustment is
not the first thing to do. Check the following first:
• Make sure nothing is interfering with the measurement: heat sources,
temperature dierences, or condensation.
• Check that there is no moisture on the probe. If the sensor has become wet,
wait for it to dry.
• Always wait for the measurement to stabilize.

Error messages
Probes can communicate with error messages when they are connected to Indigo80 indicator
or Insight software. The messages are categorized according to the severity of the status:
• Critical errors are fatal to the operation of the device. It may not be able to respond to
communication at all, and will not measure correctly.
• Errors prevent normal operation of the device. Depending on the problem, errors may
resolve themselves. For example, a completely wet humidity sensor may cause a humidity
measurement error.
• Warnings do not prevent normal operation but may indicate possible problems.
• Status indicates a known state of the device.
