Temperature Setpoint Adjustment
(C7110D1009A)
Depending on the type of wheel in use on the C7110D1009A,
the corresponding controller must be set for either the relative
or the absolute scale. The relation between setpoint and
resistance is given in Table 2.
The accuracy of resistance is:
5% in middle position, e.g., 5225 Ω to 5775 Ω
▪
10% in end position, e.g., 9450 Ω to 11550 Ω.
