Command Reference
Release 3.1 47
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 CMODEON 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 CMODEON 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
