    Reboot Certain changes to the configuration are only applied after the device has rebooted. There are two different ways of rebooting egnite Querx – via the web interface (soft boot) or by interrupting the power supply (cold boot). 11.1.1 Soft Boot It is sometimes required to reboot the device after changing settings.

  • Page 99: Saving The Configuration

    Click the Choose File button labelled Backup file in the Restore configuration section and select the configuration file that you intend to activate in the dialog box. Click Upload. Finally, restart Querx via the web interface as detailed in section 11.1.1 Soft Boot.

  • Page 100: Resetting The Configuration

    When the configuration is reset via the reset button, all settings, including the network configuration, are reset and the device is returned to factory settings entirely. This function is primarily used if Querx is no longer accessible via the network. 11.3.1 Resetting the Configuration Via the Web Interface Open the page Maintenance / Reset in the configuration area.

  • Page 102: Firmware-Updates

    Querx product range. If required, these firmware updates can be saved on your device and activated. https://www.egnite.de/support-en/firmware/ Querx can store two firmware images in two separate buffers. The software is copied into the internal memory and implemented when one of the buffers is activated.
  • Page 103 Select the Buffer containing the firmware image you want to activate in the section Activate firmware. Click the button Activate to activate the new firmware. Querx will now copy the buffer's contents into its internal memory and then reboot. ⚠ Attention Do not disconnect Querx from the power supply while a firmware image is being activated.

  • Page 105 However, we recommend sending the device in for maintenance. Information egnite Querx is operational without a battery. The battery does not need to be changed if the device is in ongoing operation under normal operating conditions (at a temperature of approx. 23 degrees centigrade).
  • Page 106 In order to change the battery you will need: Two Phillips screwdrivers, sizes PH0 and PH1  A replacement battery, type Renata CR1225  ⚠ Attention Take care not to touch any electrical contacts while changing the battery. Electrostatic discharges (ESD) can damage the device immediately or in the long run.

  • Page 112 Enter the measured value into the input field Lower reference value. Click the button Measure. Raise the value measured by Querx to a higher level by increasing the measured parameter (i.e. temperature, humidity or air pressure) and measure it with the reference device.
  • Page 113 Calibration history by entering any string of text into the input field Annotation before clicking Save. Since Querx can only save the data of up to 30 calibration processes, and it can not be deleted once saved, it is recommended to only use this feature after making sure that you will really require the data in the history permanently.

  • Page 126: Inaccuracies In Extreme Conditions

    12.2 Inaccuracies in Extreme Conditions The capacitive humidity sensor is made of a thin polymer film that is located between two electrodes. Depending on the humidity, the polymer absorbs or releases vapor contained in the surrounding air. This changes the polymer film's dielectric properties and thus the sensor's capacitance.
