Setpoint tolerance temperature sweep

Overview

As discussed in detail in Section 3, the setpoint tolerance feature allows the unit to gener-

ate an SRQ when the measured temperature is within a certain percent tolerance of the set-

point for a speciﬁc number of readings. This feature can be used to generate temperature

sweeps, as we will now discuss.

Figure E-1 demonstrates the basic method for generating temperature sweeps. Once the

temperature stabilizes at the Initial Setpoint, a step change is made in the setpoint setting.

Once the temperature is within the programmed setpoint tolerance, the Model 2510 gener-

ates an SRQ to the computer to indicate that the new setpoint has been reached. The pro-

cess is then repeated for as many steps in the temperature sweep as required.
