Command	Description

CMODE	Places the supply into calibration mode.

IDATA	Calculates the slope and intercept for current programming.

IHI	Sets the current output to the high calibration point.

ILO	Sets the current output to the low calibration point.

IRDAT	Calculates the slope and intercept for current readback.

IRHI	Sets the current output to the high readback point.

IRLO	Sets the current output to the low readback point.

OVCAL	Calibrates the over voltage protection (OVP).

VDATA	Calculates the slope and intercept for voltage programming.

VHI	Sets the voltage output to the high calibration point.

VLO	Sets the voltage output to the low calibration point.

VRDAT	Calculates the slope and intercept for voltage readback.

VRHI	Sets the voltage output to the high readback point.

VRLO	Sets the voltage output to the low readback point.

Table 3.8	Status Commands
Command	Description

ASTS?	Asks for the supply’s accumulated status register.

FAULT?	Asks for the supply’s fault register for the status preset operating
	conditions.
MASK	Prevents the supply's previously unmasked operating conditions from
	setting bits in the fault register.

STS?	Asks for the supply’s present status register.

UNMASK	Enables you to select those supply's operating conditions that you are
	most interested in monitoring for fault occurrence.

UNMASK?	Asks for the supply's fault conditions which are currently enabled
	(unmasked).
