VLIM?	return the current value of the upper limit on VSET programming. The
	response is a <value>.
	Syntax	VLIM? <ch>
	Parameters	the number of the channel to be queried.
	Category	Settings	Type: Sequential
VLOAD?	return load voltage measurement of the Power Module. The response
	is a <value>. If auto-polarity is enabled, negative output values will be
	preceded with a minus sigh.

VLOW	program the lower window warning level for the load voltage of the
	Power Module.
	Syntax	VLOW <ch>,<value>
	Parameters	the number of the Power Module to be programmed.
		the value to be set as the lower window warning
		level for the load voltage. The upper limit of the
		programmed value is VSET.
