To set the voltage of output 1 to 5 volts, send:
OUTPUT 705; "VSET 1,5"
To set the current of output 2 to 450 milliamps, send:
OUTPUT 705; "ISET 2,.450"
Output Voltage and Current Measurement. You can instruct the supply to measure the actual output voltage and
current at a specified output using the VOUT? and IOUT? queries, respectively.
To measure the output voltage at output 1, send:
OUTPUT 705; "VOUT? 1''
To get the measurement from the output buffer, send:
ENTER 705; A
DISP A
The computer should display a reading of approximately 5 volts.
To measure the output current at output 2 send:
OUTPUT 705, "IOUT? 2"
To get the measurement from the output buffer, send:
ENTER 705; A
DISP A
Output On/Off. You can turn a specified output on or off. Individual outputs can be controlled as shown below.
To turn off output 1, send:
OUTPUT 705; OUT 1,0
When an output is turned off, it is set to 0 volts and to the minimum current limit value.
To turn on output 1, send:
OUTPUT 705; "OUT 1,1"
When an output is turned on, it will return to the voltage and current settings determined by the present VSET and ISET
values.
Overvoltage Setting. You can send an overvoltage setting value to the power supply directly in volts. If the output
voltage exceeds this setting, the output crowbar is fired, and the output voltage is quickly downprogrammed and disabled
(0. volts output).
To set the overvoltage value of output 2 to 3.5 volts, send:
OUTPUT 705; "OVSET 2,3.5"
