10.3 Check the Fuses - Automatic Circuit Breaker
A measurement must be ended and the analyser switched off (main switch) before a fuse can be
checked or replaced. Unlock the housing using the key. The automatic circuit breaker is on the rear
installation plate (Fig. 25, page 36). If a fuse has blown, tilt the lever back up to its original position.
The cooler has 2 x internal 5 AT fuses, which can be checked and/or replaced by unscrewing them from
the back of the plate on the cooler when the rear housing part is opened.
