Output Control Keys

OUTPUT SELECT - Selects one of the output channels

36, 37,

 

(These twelve keys are

for local control or display. This key allows the channels

83, 83

 

output dependent).

to be selected in forward (ç) or reverse (è) sequence.

 

 

 

VSET - Displays the selected output's present voltage

37, 62,

 

 

setting. The setting can be changed using the numeric

63, 83

 

 

entry keys.

 

 

 

ISET - Displays the selected output's present current

37, 62,

 

 

setting. The setting can be changed using the numeric

63, 83

 

 

entry keys.

 

 

 

OUTPUT ON/OFF - Toggles the selected output on and

63, 83

 

 

off. When off, "DISABLED" appears on the display.

 

 

 

OVSET - Displays the selected output's overvoltage trip

37, 63,

 

 

point. The setting can be changed using the numeric entry

83

 

 

keys.

 

 

 

OVRST - Resets the selected output's overvoltage

37, 63,

 

 

crowbar (the cause of the overvoltage must be removed

83

 

 

before reset is successful).

 

 

 

OCP - Toggles the selected output's overcurrent

37, 63,

 

 

protection circuit on and off.

83

 

 

OCRST - Resets the selected output's overcurrent

37, 63,

 

 

condition and returns the output to its previous settings

83

 

 

(the cause of the overcurrent must be removed before reset

 

 

 

is successful).

 

 

 

METER - Returns the display to the metering mode from

83

 

 

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

69, 83

 

 

specified channel. The setting can be changed using the

 

 

 

numeric entry keys.

 

 

 

UNMASK - Displays the present setting of the mask

63, 83

 

 

register for the specified channel. The setting can be

 

 

 

changed using the numeric entry keys.

 

 

 

FAULT - Displays the contents of the fault register for

68, 68,

 

 

83

 

 

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.
