Status Commands
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).
