11. Maintenance Tips
To secure the accuracy of your measuring instrument we recommend the annual check by an
authorized ecom partner.
WARNING If sensors from other manufacturers are used, the TüV approval of the
instrument expires.
Use only sensors from ecom or from an ecom authorized service
centre.
WARNING Service made by service centres non-authorised by ecom GmbH will result in a
complete and immediate loss of any warranty!
Have service work performed only by ecom or by ecom
authorized service centre.
Hint
In the case of strong use (e.g. permanent several hours of measurement per
day, rough conditions etc.) shorter intervals between checks should be
selected.
Please contact your ecom partner. All ecom partners are listed
under www.ecom.de.
The following components should be checked every time the instrument is used:
