Check sensors

When there is a sensor alarm, an alarm indicator is shown in the tab Maintenance.

All functions to check the status of the sensors are grouped under button Check sensors.

• Check Fill stop sensor: Click the Check button. The green light is shown if the sensor value is in range.
• Check temperature sensor: Value must be equal to the actual room temperature near the pipette belt.
  The value can be set in tab Settings.
• Check Diluter start sensor: This sensor is only used in EDTA mode. If the diluter does not start during the aspiration, the status of this sensor must be checked.
  Click the Check button. The green light is shown if the sensor value is in range.

  EDTA mode is used for undiluted samples collected in tubes with EDTA anticoagulant. The samples are automatically diluted on the Starrsed during aspiration.
  The usual amount of EDTA in sample tubes is 1.8 mg per 1 ml blood. 1 ml of blood weighs ca. 1060 mg and the concentration of EDTA is therefore 0.17% and well within the requirements for the EDTA mode on this instrument.

• Check Diluent flow sensor: This sensor is only used in EDTA mode. When activated, the LED Down is green and the LED Up is red. When the button Test is clicked, the LED Up must become green. After finishing the test, both LED's must be green.
• Check Separator sensor: Click the Check button. The green light is shown if the sensor value is in range.
• Check Flow sensor: Click the Check button. The green light is shown if the sensor value is in range.
• Check Measure sensor:
  Clean sensors first before executing this function.
  Click the Check button. The green light is shown if the sensor value is in range.
  Press the button Measure. The pipette currently at the measure position will be measured.
  The results are displayed in graphical form:

When a test pipette is installed at the measuring position the result of the test pipette is displayed in the field "ESR (mm)".
