Output Control Keys (These twelve keys are output dependent).

OUTPUT SELECT - Selects one of the output channels for local control or display. This key allows the channels to be selected in forward (∠) or reverse (∉) sequence.

VSET - Displays the selected output’s present voltage setting. The setting can be changed using the numeric entry keys, ∇ VOLT, or VOLT keys..

ISET - Displays the selected output’s present current setting. The setting can be changed using the numeric entry keys, ∇ CURR, or CURR keys.

OUTPUT ON/OFF - Toggles the selected output on and off. When off, "DISABLED’’ appears on the display.

OVSET - Displays the selected output’s overvoltage trip point. The setting can be changed using the numeric entry keys.

RANGE V/I - Displays the selected output’s full scale programming range for voltage and current. This key also enables the Up/Down keys to change the programming range.

Up/Down Keys - These keys increment or decrement the voltage or current settings of the output selected. The display will be in the metering mode for the output selected. When one of the keys is pressed, it will change the output selected by one least significant bit (LSB). If the key is pressed and held, it will continually change the setting until it is released The ∇ VOLT key is disabled when the supply is in the CC mode. The CURRENT key is disabled when the supply is in the CV mode.

These keys will also allow you to change the programmed resolution range of voltage or current after the RANGE V/I key is depressed.

∇VOLT - Increases the selected output voltage by an LSB and then a faster rate as the key is kept pressed, or after the RANGE V/I key has been pressed, sets the selected output to the high voltage range.

3-9, 6-2

VOLT - Decreases the selected output voltage by an LSB and then at a faster rate as the key is kept pressed, or after the RANGE V/I key has been pressed, sets the selected output to the low voltage range.
