To calibrate the flask level sensor, follow these steps:
➜
Switch on the control box and wait approximately 10 minutes for the electronics
to warm up to operating temperature. In this way, measurement inaccuracies are
avoided during calibration!
Calibration to maximum sensitivity, low-polar solvents:
➜ Remove the sensor from the evaporation flask.
➜ Hold the sensor in the open space.
➜
Make sure there are no objects or bodies in a hemispherical space one (1) meter
in front of the sensor head. These would be detected as a signal and falsify the
calibration result!
➜
Start the calibration process in the device software:
– Open the main menu using the
the start window:
Settings
– Open the
also "Main menu" on page 100).
– Follow the instructions on the display.
OR
Calibration on high-polar solvents and mixtures:
➜ Make sure the sensor is in the flask.
➜
Fill the evaporation flask with at least 500 ml of the product.
➜
Slide the sensor into the standing piston until the sensor head is just above the
fluid level or – for example, in the case of mixtures with water – until the sensor
head touches the fluid level slightly.
