Maintenance and service
4.1
Zero point correction
The zero position of a pressure sensor shifts over time due to external influences and the condition of the piezoresistive
sensor element. It is therefore recommended to carry out a zero point correction before commissioning and at annual inter-
vals thereafter. To do this, connect the supply voltage to terminals 1 and 2 and then press the „S“ key. The current measured
value is now zeroed.
Danger
When working on the open device, always ensure that either the supply voltage is interrupted or suitable
protective measures have been taken against contact with live parts.
4.2 Cleaning
Cleaning of the equipment can be done with a damp cloth. Remove external soiling from the housing, the connections and
the display.
Notice
Do not use sprays, solvents, alcohol-based cleaners or abrasive cleaners to dampen the cloth.
Remove soiling of the housing, the connectors and the display.
4.3 Repair
Notice
Repairs may only be carried out by the manufacturer or appropriately authorized and qualified personnel.
If changes are made to the device independently, the warranty will expire.
