Command

Description

FOLD?

Asks for the supply’s present foldback setting.

 

Response: FOLD <mode> where mode is:

 

0 (OFF) or

 

1 (CV or Constant Voltage mode) or

 

2 (CC or Constant Current mode)

HOLD <1/ON>,<0/OFF>

Enables or disables voltage/current setting hold mode for the supply. When

 

HOLD ON is specified, hold mode is enabled so that all voltage and current

 

settings which would normally be implemented by the supply are held until a

 

TRG (trigger) command is received. This feature allows you to synchronize

 

the operation of several supplies.

 

Initial value: HOLD OFF or HOLD 0

HOLD?

Asks for the present hold mode setting.

 

Response: HOLD 0 (OFF or disabled) or

 

HOLD 1 (ON or enabled)

ID?

Asks for the power supply model and the master EPROM version.

 

Response: ID <model name><version>

IDATA <Ilo>,<Ihi>

Calculates and records the slope and offset for programmed current using

 

ILO and IHI data. Set CMODE ON before using this command. See also the

 

calibration procedures in Section 4.

 

<Ilo> and <Ihi> are in <current> format.

IHI

In response to this command, the power supply sends a programmed

 

current value to the output terminal. This value is at the high end of the

 

power supply’s current range and is read by an external device connected

 

as part of the calibration procedure. Refer to this value as IHI and record it

 

to use as input with the IDATA command. Set CMODE ON before using this

 

command. See also the calibration procedures in Section 4.

ILO

In response to this command, the power supply sends a programmed

 

current value to the output terminal. This value is at the low end of the

 

power supply’s current range and is read by an external device connected

 

as part of the calibration procedure. Refer to this value as ILO and record it

 

to use as input with the IDATA command. Set CMODE ON before using this

 

command. See also the calibration procedures in Section 4.

IMAX <current>

Sets an upper soft limit on the supply’s programmed output current. If the

 

soft limit is exceeded, or if the soft limit value is lower than the present

 

output current setting, the supply will ignore the command, turn on the

 

ERR LED, and set the ERR bit in the bit registers.

 

Range: 0 to model maximum output current (IMAX)

 

Initial value: model IMAX

IMAX?

Asks for the supply’s soft current limit setting.

 

Response: IMAX <current>

IOUT?

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

 

readback circuitry.

 

Response: IOUT <current>
