With the new sensor tester we offer a quick, easy and economical solution to indicate to the technician, prior to a measurement, if all selected sensors are fully operable or if a damage has been occured. By measuring all signals against each other (short circuit!) and verification of ID modules either full or half bridge sensor can be connected (bridge completion). The little battery operated hand device can be started over one push button and the results are being displayed over multi-colour LEDs.
