CAL:VOLT:PROT

This command can only be used in the calibration mode. It calibrates the power module overvoltage protection (OV) circuit. The power module output must be enabled and operating in the constant voltage (CV) mode. The power module automatically performs the calibration and stores the new OV constant in nonvolatile memory. CAL:VOLT:PROT is a sequential command that takes several seconds to complete.

Command Syntax:	CALibrate:VOLTage:PROTection
Parameters	(None)
Example	CAL:VOLT:PROT
Query Syntax	(None)
Related Commands	CAL:STAT

Current Subsystem

This subsystem programs the output current of the power module.

CURR

This command directly programs the immediate current level of the power module. The immediate level is the current applied at the output terminals. This command is always active, even when the current subsystem is in the list mode (see CURR:MODE).

Command Syntax	[SOURce]:CURRent[:LEVel] [:IMMediate][:AMPLitude] <NRf+>
Parameters	See Table 3-2
Default Suffix	A
*RST Value	See Table 3-2
Examples	CURR 500 MA	CURR:LEV .5
Query Syntax	[SOURce]:CURRent[:LEVel] [:IMMediate][:AMPLitude]?
	[SOURce]:CURRent[:LEVel] [:IMMediate][:AMPLitude]? MAX
	[SOURce]:CURRent[:LEVel] [:IMMediate][:AMPLitude]? MIN
Returned Parameters	<NR3> CURR? returns the present programmed current level.
	CURR? MAX and CURR? MIN return the maximum and minimum
	programmable current levels.
Related Commands	SAV RCL	*RST

CURR:MODE

This command enables or disables list subsystem control over the power module output current. When programmed with FIX, this command prevents the output current from being controlled by the sequencing of points specified by LIST:CURR. If the LIST parameter is used, then the output current may be changed by the subsequent execution of a list. However, the list mode does not prevent the output current from being set by CURR and *RCL.

Note	CURR:MODE:LIST is an implied ABORt command.
	Command Syntax	[SOURce]:CURRent:MODE <CRD>

	Examples	CURR:MODE LIST CURR:MODE FIX
	Query Syntax	[SOURce]:CURRent:MODE?
