    Viscometer tube calibration values are associated with specific temperatures. A calibration must be performed any time the CAV 4.1 bath is operating at a new temperature. Once the tube is calibrated at a particular temperature, the instrument saves the C and E constant values. The values are then automatically recalled if the tube is run at that temperature again.
