Functional Description The operation of the measuring section of the RESISTOMAT® model 2304 high-precision inspection and test unit is based on an upgraded 4-wire design. It measures not only the voltage drops with injected current across the test object but also across an internal reference resistor. The quotient is calculated from both voltage drops. The resistance of the test object is calculated by multiplying this with the characteristic value of the reference resistor. Apart from eliminating the error of contact layer and contact resistance, this method has the advantage that errors reduce...

Technical Data Technical Data The device is designed in a modular system and embedded in a stable housing of sheet steel. Therefore every structural component is easily accessible and thus an optimal service is secured. All operational control elements, the LCD graphic display and the connector box are situated clearly and easy to survey on the front panel. On the rear panel the in- and outputs of the interfaces are placed as well as of the comparators and the Pt100 sensor for temperature compensation and for controlling the instrument. Measuring method: Quotient method with Kelvin-4-terminal...
