Command | Description |
|
IOUT? | Measures the supply’s actual current output using the | |
| readback circuitry. | |
| Response: IOUT <current> | |
|
|
|
IRDAT <Ilo>,<Ihi> | Calculates and records the slope and offset for readback voltage using | |
| IRLO and IRHI data. Set CMODE ON before using this command. See also | |
| the calibration procedures in Section 4. | |
| <Ilo> and <Ihi> are in <current> format. |
|
IRHI | The power supply outputs a current value to an external device connected | |
| as part of the calibration procedure and records a current readback value | |
| internally. These values are at the high end of the programmed current | |
| range. Refer to the output value as IRHI and record it to use as input with | |
| the IRDAT command. Set CMODE ON before using this command. See | |
| also the calibration procedures in Section 4. |
|
IRLO | The power supply outputs a current value to an external device connected | |
| as part of the calibration procedure and records a current readback value | |
| internally. These values are at the low end of the programmed current | |
| range. Refer to the output value as IRLO and record it to use as input with | |
| the IRDAT command. Set CMODE ON before using this command. See | |
| also the calibration procedures in Section 4. |
|
ISET <current> | Sets the power supply’s output current in amps (default) or in milliamps. | |
| This programmed current is the actual output in CC mode or the current | |
| limit in CV mode. | |
| Range: 0 to model maximum output current (IMAX) | |
| Initial value: 0 amps | |
|
|
|
ISET? | Asks for the supply’s present output current setting. Does not apply to | |
| current settings which are being held. See HOLD command. | |
| Response: ISET <current> | |
|
|
|
LLO | Disables the front panel LOCAL switch. When LLO is in effect you can only | |
| return to local mode using the GTL command. You can remove the local | |
| lockout with the REN command. See also “Remote/Local Operation” on | |
| page 27. |
|
MASK <mnemonics> | Disables the supply's previously unmasked operating conditions from | |
| setting bits in the fault and status registers. See “Accumulated Status, | |
| Status, and Fault Registers” on page 51. Mnemonics are separated from | |
| each other by commas and may be sent in any order. | |
| Mnemonics: CV, CC, OV, OT, SD, FOLD, ERR, PON, REM, ACF, OPF, | |
| SNSP | |
| Note: UNMASK NONE = MASK ALL (Initial value) | |
| MASK NONE = UNMASK ALL | |
