Figure 6-1. Front Panel (Model 6624A shown)

Pressing the ENTER key will enter the values displayed for the function indicated, initiate that function, and return the display to the metering mode in which the measured output voltage and current for the selected output are displayed. Pressing the ENTER key without entering numbers will result in retention of the previous values and return to the metering mode. You can also return to the metering mode at anytime by pressing the METER key.

Setting Voltage

The selected output’s voltage is programmed locally using the VSET key. For example, program the voltage to 5.25 volts by pressing:

VSET

5

.

ENTER

The front panel display then indicates the actual output voltage and current for the selected output.

Setting Current

The selected output’s current is programmed locally using the ISET key. For example, program the current to 1.5 amps by pressing:

VSET

1

.

5

ENTER

The power supply will accept any programmed current between zero and the minimum programmable current and automatically set the output to the minimum programmable current without causing a programming error. See Table 5-4.

NOTE

As described on page 70, each output channel has a dual output range. The range is determined by the last

 

value of voltage (VSET) or current (ISET) programmed.
