11.2.2. Set the Current Limit
This command sets the current limit. When the power supply is running in constant-
current mode, this will be its output current
The current limit, rounded to four digits, may be viewed on the supply front panel by
pressing and releasing the PREView button
Syntax: [SOURce:]CURRent[:LEVel][:IMMediate][:AMPLitude]
<nn.nn>
Parameter: <nn.nn> is amps, from zero to 5% more than the current rating
Examples: CURR 172.75
:CURR 172.75
Query: CURR? will return 172.75 in example
(this may be different than the actual output current)
Errors: SYSTEM:ERROR? may return errors including:
222, “Data out of range”
11.2.3. Set the Output ON or OFF
This command turns the power supply output on or off.
The output on command may not work as expected. The latching power supply faults,
including AC fault, over-temperature, J1-Enable and J1-Shut Off, will prevent turning
the output on until the fault clears. For non-latching faults, including over-voltage and
current fold-back, turning the output on will clear the fault
Syntax: OUTPut:STATe <0|1|OFF|ON>
Parameter: 0 or OFF will set the power supply output to OFF
1 or ON will set the power supply output to ON, if it is able to
Example: OUTP:STAT 1 (or OUTP:STAT ON)
Query: OUTP:STAT? will return ON in the example, otherwise OFF
Errors: SYSTEM:ERROR? may return errors including:
+307, “On during fault”
11.3. Measuring the Output
11.3.1. Measure the Output Voltage
This returns the measured voltage at the output terminals (or remote sense point)
Syntax: MEASure:VOLTage?
Example: MEAS:VOLT? may return 02.006
Response: Volts as a 5-digit number, which is one decimal place more than
the power supply’s front panel voltmeter
11.3.2. Measure the Output Current
This query returns the measured current at the output terminals
Syntax: MEASure:CURRent?
Example: MEAS:CURR? may return 009.48
Response: Amps as a 5-digit number, which is one decimal place more than
the power supply’s front panel ammeter
