Voltage and current limit operating boundaries
The combination of the voltage and current limits restricts the allowed operating area, or
operating boundaries, as shown in
Figure 3-1 . In this example, the voltage limit is set to
5V, while the current limit is 2A. The shaded areas of the graph show output currents or
voltages that are restricted by the respective limits.

Setpoint tolerance
The setpoint tolerance feature allows you to program the Model 2510 to indicate when the
setpoint is within the desired range, or window, for a certain number of readings. For
example, with a tolerance of 1%, the setpoint will be within tolerance when the tempera-
ture is within ±2.75˚C of the setpoint for the programmed number of readings.
