Maintenance And Adjustment - Lufft E200 Manuel D'utilisation

7. Maintenance and adjustment

When used in the area of climate-control technology we recommend
annual maintenance. Recalibration should be carried out more
frequently in a harsh environment.
For the purposes of calibration you should use the calibration block
that can be obtained as an accessory, and the appropriate calibration
fluids.
Before it is checked or adjusted the device and the calibration block should
be stored at a temperature of approximately 20 °C..25 °C for 12 hours.
Recalibration should only be carried out in the calibration block
or, better still, at accredited laboratories.
