12.6 Checking the sensor
The Sensor testing function in the Viewer allows users to test the accuracy of the sensor. A
test report is created for documentation purposes.
Navigation using the Viewer
Menu "Teqwave Transmitter" → "Sensor testing"
NOTICE
Incorrect test result
The use of tap water and the presence of air bubbles or variable environmental conditions
(e.g. variations in temperature or flow) can corrupt the test result.
‣
Clean the sensor before performing the test.
‣
Only use distilled or fully deionized water (conductivity < 20 µS/cm to test the sensor.
‣
Boil the liquid for several minutes to prevent air bubbles occurring.
‣
Ensure constant environmental conditions.
1. Call up the menu "Teqwave Transmitter" → "Sensor testing".
 A message appears with information on the preparatory steps. If using the
"Teqwave I" sensor, immerse the sensor fully in a vessel containing distilled or
completely deionized water. If using the "Teqwave F" sensor, fill the sensor
completely with distilled or completely deionized water.
2. Click "OK" to confirm the message.
 View in the Viewer changes to the Test View. If the temperature of the liquid and
sensor is stable, the message "The temperature is stable. Start sensor testing?"
appears after approximately three minutes.
3. Click "OK" to confirm the message.
 The sensor test begins. The test result appears in the form of a test report after a
few seconds.
4. Click "OK" to save the test report as an image file (.bmp) on the computer.
 The "Specify path" window opens.
5. Select the path and file name for saving the .bmp file.
6. Click the "OK" button to confirm.
 The Viewer saves the test report.
7. Check the test report. If the test values are outside the tolerance range, the sensor
may need to be adjusted. In such cases, please contact your Hauser Sales
Center. Permitted deviations for the speed of sound: ± ≤ 0.5 m/s and for the density:
± ≤ 3.0 kg/m
