Maintenance and adjustment

A yearly calibration is recommended. However it is advisable to
recalibrate the instrument at more regular intervals when it is used
in severe environments.
The calibration block and the corresponding calibration solutions
(available as accessories) are required to carry out the calibration.
Prior to controling or adjusting, the instrument and the calibration
block should be kept at a temperature of 20°C to 25°C during
12 hours.
Recalibrations should be exclusively carried out with the calibration
block or by an accredited calibration laboratory.
The instrument can be cleaned by using a humid cloth and clear
water. Prior to cleaning, ensure that the instrument is switched off.
Never use acid detergents or dissolvants for cleaning and
avoid any contact with the sensor.
