Resistance measurement is an important quality control factor in many fields. With battery pack contact terminals – whether in electromobility, power tools or communication electronics – contact resistances in the milliohm range provide information about the quality of the spot-welded joint and its high-current capability. Similarly, motor or relay coils can be tested quickly and reliably, as can fuses, wire coil heating elements, solenoid coils, plug contacts or switches. For these important tasks, burster präzisionsmesstechnik has developed RESISTOMAT 2311, a high-precision milliohmmeter for the fastest inline measurements in manufacturing processes (see fig. 1). Capable of up to 100 measurements per second, it is ideally suited to 100% checking in mass production. The compact measuring instrument (110 x 110 x 183 mm) offers measuring ranges from 20 mΩ to 200 kΩ with a measurement accuracy of 0.03 % of full scale.
