The control unit B includes all control-, monitoring- and measuring functions required for determination of the molecular weight.
The measuring parameters are manually adjusted by switches on the front panel of the device. The 4-digit display alternatively shows the actual measured result (1 digit is equivalent 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 calculation of the final molecular weight Mn is performed by the user (the control unit SA offers a complete evaluation with a final report).
