12.1.2 Calibration
Sensors
• Sensors with Memosens protocol are calibrated at the factory.
• Users must decide whether the process conditions present require calibration during
initial commissioning.
• Additional calibration is not required in many standard applications.
‣
Calibrate sensors at sensible intervals depending on the process.
Operating Instructions "Memosens", BA01245C
All connected sensors can be calibrated while a sampling program is active.
Distribution arm
The position of the distribution arm is set at the factory. It is only possible to calibrate the
distribution arm in the version with multiple bottles.
The distribution arm must be calibrated if:
• The distribution arm motor has been replaced
• Error message "F328 Distribution arm" appears on the display
Proceed as follows to calibrate the distribution arm:
1. Make the setting for the number of bottles in the "Setup/Basic setup" menu.
2. Under menu Calibration active/Distribution arm/Go to ref. point
The reference run is started. The reference point is in the middle at the front. For
the version with a distributor plate, the reference point is at the arrow in the
middle of the plate.
With Adjust, you can correct the distribution arm if the unit does not move to the
reference point correctly. Use the two arrow keys to correct the position.
3. Perform the distribution arm test in the menu Diagnostics/System test/Reset/
Distribution arm"
Sample volume or vacuum pump
The dosing volume of the vacuum pump is set to 200 ml (6.76 oz) at the factory. The
required sample volume is set by moving the dosing pipe manually.
NOTICE
Calibration not possible during operation.
The sample volume cannot be determined.
‣
Stop the sampling program before calibrating the sample volume.
