Maintainer is a module used for maintenance and inspection. Normally maintenance for inspection and audit can be generated from the module along with work orders to support fieldwork. Every single object can have several inspection plans, i.e.annual inspection of poles. When an inspection is planned for execution, it can be grouped with similar inspections to an inspection round. An inspection round can be exported to PDA for field inspection. If PDA has a GPS the object will automatically comes up in PDA and it is possible to see a map of currently inspected objects.
