Warning advice The potentiometer tester K154433N50 is an electronic measuring device, which must be protected against excessive humidity and heat. The tester must only be connected to brakes which are supplied with a Knorr-Bremse ‘continuous’ or a ‘black/white’ sensor (potentiometer). The tester supplies voltage to the brakes being measured and therefore it must only be connected where there is no voltage, either external or from the vehicle.
