D.5 Temperature Comp.
The window for the Temperature Comp. command is similar to Figure 84 below.
Figure 84: Temperature Comp. Window
The first command asks for the
PWM (pulse-width-modulation) for point #1. PWM represents the ratio of the heater ON
time to the heater
OFF time. It acts to compensate for drift due to changes in ambient temperature. Enter the desired
percentage of time the heater is
ON, and click on Next Item/Enter to confirm the entry. (For any command, click
Previous Item to return to the previous parameter, or Exit Page to close the window without changing any values.)
At the next command, as shown in Figure 85 below, enter the
K-factor (the compensation for the PWM percentage) for
point #1.
