ler percent output power display. Narrow the proportional band width to the
point at which the bath temperature begins to oscillate and then increase the
band width from this point to 3 or 4 times wider. Table 4 lists typical propor-
tional band settings for optimum performance with a variety of fluids at se-
lected temperatures.
