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 (Ð) or reverse (Ï)
sequence.
3-7, 3-8,
6-1--6-4
VSET - Displays the selected output’s present voltage
setting. The setting can be changed using the numeric
entry keys, Ñ VOLT, or Ò VOLT keys..
3-8, 3-9,
5-9, 5-11,
6-2
ISET - Displays the selected output’s present current
setting. The setting can be changed using the numeric
entry keys, Ñ CURR, or Ò CURR keys.
3-8, 5-11,
6-3
OUTPUT ON/OFF - Toggles the selected output on
and off. When off, "DISABLED’’ appears on the
display.
5-12, 6-3
OVSET - Displays the selected output’s overvoltage trip
point. The setting can be changed using the numeric
entry keys.
3-8, 5-12,
6-4
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.
3-9
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 Ñ VOLT key is
disabled when the supply is in the CC mode. The Ò
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.
3-9, 6-2,
6-3
3-9
Ñ 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
Ò 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.
3-9, 6-2
