Page 34: General Operation
7 General Operation General Operation Heat Transfer Fluid Many fluids will work with CTR –40 bath. Choosing a fluid requires consider- ation of many important characteristics of the fluid. Among these are tempera- ture range, viscosity, specific heat, thermal conductivity, thermal expansion, electrical resistivity, fluid lifetime, safety, and cost. -
Page 35: Specific Heat
7 General Operation 7.1.3 Specific Heat Specific heat is the measure of the heat storage ability of the fluid. Specific heat, to a small degree, affects the control stability and the heating and cooling rates. Generally, a lower specific heat means quicker heating and cooling. The proportional band may require some adjustment depending on the specific heat of the fluid. -

Page 74: Calibration Procedure
10 Calibration Procedure Calibration Procedure In some instances the user may want to calibrate the bath to improve the tem- perature set-point accuracy. Calibration is done by adjusting the controller probe calibration constants R0 and ALPHA so that the temperature of the bath as measured with a standard thermometer agrees more closely with the bath set-point. - Page 75 10 Calibration Procedure R0 = 100.000 ALPHA = 0.0038500 = 30.00°C measured t = 29.843°C = 80.00°C measured t = 79.914°C Compute errors, = 29.843 - 30.00°C = -0.157°C = 79.914 - 80.00°C = -0.086°C Compute R0′, ϒ (−0.086) × 30.0 − (−0. 1 57) × ⁄...
