Servicing
There are no moving parts or user-serviceable parts requiring routine maintenance.
Opening the unit or breaking the security seal will void the warranty and the calibration.
In the event of failure, prior to returning the unit to your authorised Gill distributor, it is
recommended that:
All cables and connectors are checked for continuity, bad contacts, corrosion etc.
A bench test is carried out as described in Section 10.6.
Contact your supplier for advice if failure persists.
