Command

Description

 

IOUT?

Measures the supply’s actual current output using the built-in current

 

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
