Returning the Gauge for Servicing

A full Manufacturer’s Factory Service is available from Cygnus

Instruments.

The Complete Kit should always be returned for Service or

Repair, including all Probes and Leads.

Cygnus Gauges are renowned for their reliability, very often

problems with getting measurements are simply due to the way

the Gauge is being used.

However, if you do need to return your Gauge for Repair please let

us know the details of the problem, to help us guarantee the best

possible service:

•

Is the problem Intermittent Behaviour?

•

Is there a problem turning the Gauge On?

Or a problem with the Gauge turning itself Off?

•

Does the Gauge constantly give Incorrect Readings, or

Unsteady Readings?

•

Is it not possible to Calibrate the Gauge?
