WARNING ADVICE / BRAKE IDENTIFICATION

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. Usage contrary to this specification may damage the device. When fitting the battery ensure the correct 
polarity (plus and minus). Warranty claims will not be honoured if the device has been opened (except the battery compartment). 

Please also refer to the service manuals for Knorr-Bremse air disc brakes and specifications of the vehicle manufacturers. You will find Knorr-Bremse service manuals 

on our website www.knorr-bremseCVS.com
