of the Device Manager form. To select a sub-form, click on it with the left mouse button.
3.1 Device Manager Menu Bar
The Device Manager menu bar is located at the top of the form.
File
The file menu is used to save to the PC, or to retrieve from the PC, the configuration settings of the HC2AW-USB probe. The settings are saved in an XML file with the extension DAT. Saving the configuration
settings to a file is useful for several reasons:
- provides a backup when the probe configuration has been changed in error
- provides a means of quickly configuring a replacement probe in the exact same manner as the
original probe when the original probe is defective
- provides a means of quickly configuring a number of identical probes
● Open: opens the device configuration folder specified in HW4 Global Settings - File Locations Tab -
and displays all available probe and device configuration files (extension DAT). Select the appropriate
file and click on Open in the explorer form. The contents of the configuration file are loaded to the
Device Manager form. Review the contents of the Device Manager sub-forms. Click on the Device
Manager OK button to write the configuration settings to the probe or click on the Cancel button to leave

Tools
● Firmware Update: This tool is used to update the firmware of the HC2-AW-USB probe after downloading
a new firmware file from the ROTRONIC website to your PC. Firmware files are given a name that shows
both to which device the file applies and the version number of the firmware. All firmware files have the
extension HEX. The ROTRONIC website will publish firmware updates as required.
The tool opens a form that allows you to specify the folder where the firmware update file is located and to
select the file. Click on OPEN to start the update process.
IMPORTANT: the probe must be powered during the entire process. Loss of power when the probe is being
updated may have unexpected results and prevent future operation of the probe.
● Generate Protocol: generates a Device Configuration Protocol. This text file is automatically saved in the
folder specified in HW4 Global Settings - File Locations Tab. If so desired, any directory and any file type
may be specified. This action is not recorded in the User Event file.

Use of the HC2-AW-USB probe as a simulator serves the purpose of verifying the digital signal transmission
after completing an installation. Whenever the humidity and/or temperature signal is set to a fixed value, this
is reported on the HW4 main screen (current Values tab) as shown below. The fixed value is shown in red
when the probe is not selected.
3.4 Alarm
Alarm conditions can be defined for water activity, temperature and the calculated parameter. Values that
are below the low alarm value or above the high alarm value will trigger an alarm. The value specified for the
alarm function hysteresis is used for both the low and the high alarm.
All versions of HW4 will show an out-of-limits value alarm in red on the monitor screen. In addition, HW4
Professional can be configured (HW4 global settings - Alarm settings tab) to display an alarm table and
generate a report whenever an out-of-limits condition occurs.

The sensor error is less than the correction threshold value. The correction offset
(SQ) for sensor drift correction is automatically set to zero
SQ-Tuned
The sensor error is equal or larger than the correction threshold value but less
than the defective threshold. A correction (SQ) is automatically added to the value
measured by the sensor. The correction (SQ) is calculated based on the %RH
currently measured by the sensor and on the coefficients A, B and C (RH sensor
test settings).
Bad
The sensor error is equal or larger than the defective threshold value

Original release
The probe issues a digital alarm only when both of the following conditions are met: (a) the %RH
measured prior to the test is at least equal to the value entered in Tools > RH Sensor Test Settings >
Test above [%RH] box and (b) the humidity sensor test returns the result “Bad”. The text “Bad Sensor
Alarm” appears in red on the HW4 main screen. HW4 Professional can be configured (HW4 global
settings - Alarm settings tab) to display an alarm table and generate a report whenever a device alarm
condition occurs.
Check Humidity Sensor Now: this link works only when the probe is configured with the automatic
RH sensor test function enabled and when the measured value of humidity is above the limit
entered in the RH Sensor Test Settings form. When both conditions are met, click on this link to
manually run a humidity sensor test and eventually have the probe apply a correction to the
humidity output signal
