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 (ç) or reverse (è) sequence.
VSET - Displays the selected output's present voltage
setting. The setting can be changed using the numeric
entry keys.
ISET - Displays the selected output's present current
setting. The setting can be changed using the numeric
entry 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.
OVRST - Resets the selected output's overvoltage
crowbar (the cause of the overvoltage must be removed
before reset is successful).
OCP - Toggles the selected output's overcurrent
protection circuit on and off.
OCRST - Resets the selected output's overcurrent
condition and returns the output to its previous settings
(the cause of the overcurrent must be removed before reset
is successful).
METER - Returns the display to the metering mode from
any other mode (e.g. VSET). In the metering mode, the
measured output voltage and current of the selected output
are displayed.
DLY - Displays the reprogramming delay for the
specified channel. The setting can be changed using the
numeric entry keys.
UNMASK - Displays the present setting of the mask
register for the specified channel. The setting can be
changed using the numeric entry keys.
FAULT - Displays the contents of the fault register for
the specified channel. A bit gets set in the fault register
when the corresponding bit is set in both the status and
mask registers. Pressing the FAULT key also clears the
fault register.
