 | 
| 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 | |
