6.7 Sense abnormal protection function

When the Remote Measure Function (Sense Function) is enabled, after the in-
strument's On/Off switch is turned on, automatically detect the wiring conditions
of the Sense+ and Sense- terminals on the rear panel. If the Sense interface is
not connected or reversed connected, the instrument would make judgment
based on the measured voltage data. When the voltage difference between the
local voltage and remote voltage is greater than a certain value and such condi-
tion continues for a period, the instrument would report Sense abnormal protec-
tion and turn off the output. The output voltage is subject to local voltage, and
the instrument interface would prompt "Sense Protect". This protection can pre-
vent the instrument from outputting high voltage when the Sense terminal is not
wired or when the line is loosened or reverse-connected under Remote Meas-
ure state, which may damage the DUT.
