1. Examination of the delivered device on transport damages
2. Incoming inspection
- Setup of the device
- Control of LED
- Examine on contamination
- Test measurements with calibration dust and ambient air
3. Check and readjustment of the electrical components
- Working voltage
- power supply (electricity/power)
- Signal cards (adjustment of the offset, characteristic, signal
period measurement, coincidence recognition)
- Offset measurment/adjustment of Photomultiplier unit
4. Check of the optical system of the sensor
- Cleaning of the optics
- Control and adjustment of the optical light paths in the sensor
5. Check of aerosol flow circuit and working fluid flow circuit
- Change filters, cleaning (and replacement, if necessary) of tubing
and pumps
- Calibration of aerosol flow rate
6. Software
- Examination of correct installation (Are all components existing?
Are the program paths correct? Is the program version the
current one and is it exact?)
- If necessary: update of the software
7. Evaluation of the overall function and calibration for droplet size
determination, number concentration and linearity check
8. Issue of a new calibration certificate
9. Packing of the device ready for dispatch
Small repairs are included
Excluded are the following spare parts, which must be ordered
separately:
- Suction pumps (Aerosol and working fluid)
- Photomultiplier
