thru

Press to select numerical values .

Press to enter a minus sign.

Press to delete the last keypad entry. Use this key to remove one or more incorrect digits before they are entered.

3These four entry keys operate in two modes. Press and release for a single minimal change as determined by the programming resolution (see Table 1-2 in Chapter l). Press and hold for an increasingly rapid output change.

Press to delete an entire keypad entry and return to the meter mode. Use this key to exit from a value before it is entered.

Press to enter a value or to accept an existing value and return the display to the meter mode. The remaining shifted keys are for calibration (see "Appendix A - Calibration").

Line Switch

On / Off

Turns the ac line on or off.

Programming the Output

Important These instructions show how to program a single power supply. There are special considerations when you have two or more supplies connected in series or in autoparallel. See "Chapter 4 - User Connections and Considerations".

The power supply accepts values directly in volts and amperes. Values will be rounded off to the nearest multiple of the output resolution (see “Average Resolution" in Table 1-2 of Chapter 1). If you attempt to enter a value not in a valid range, the entry will be ignored and OUT OF RANGE appears on the display.

Figure 5-2 shows the general response of a typical power supply. Unless directed otherwise, always keep the output voltage and current within the boundaries of its operating line for the specified mode of operation (CV or CC).

Establishing Initial Conditions

Set the power supply to its *RST state by pressing . This state was stored in location 0 at the factory. If it

has since been changed, you can restore it as directed under “Turn-on Conditions”, later in this chapter. *RST results in the following operating conditions:

■Zero voltage output.

■Minimal current output.

■Output disabled (Dis annunciator on).

■Overcurrent protection off (OCP annunciator off).

■Protection circuits cleared (Prot annunciator off).
