The control unit B includes all control-, monitoring- and measuring functions required for determination of the molecular weight. The measuring parameter are manually adjusted by switches at the front panel of the device. The 4-digit display alternatively shows the actual measuring result ( 1 digit equals to 1mV) at the output of the amplifier or the actual temperature of the measuring cell. A potentiometric recorder can be connected to the control unit B (recommended sensitivity 1 Volt full scale).
The evaluation for the final molecular weight Mn has to be done by the user himself (whereas the control unit SA offers a complete evaluation with a final report).
