Load Function
When you return power to the instrument, verify that the cooling
fan is running. If not, please contact ITECH Technical Support.
Leaving the instrument powered on with an inoperative cooling
fan may result in damage to the instrument.
5.3.5 Sense Reverse Protection
The instrument defaults to provide sense reverse protection. The premise is that
the Sense switch is turned on. When the output state is ON and the difference
between output terminal voltage and sense remote voltage exceeds the speci-
fied voltage, sense reverse protection will be enabled after 500ms. The instru-
ment output will be immediately switched to Off and the display screen will
display SENSE ERR if the sense terminals are reversed.
When the instrument is in Sense Reverse Protection state, you should check
whether the polarities are connected reversely or not firstly. If yes, you can re-
open the output after the polarities connect correctly.
The voltage difference between output terminal and remote sense terminal of
each model is not the same. When the remote sense terminal is connected re-
versely, the maximum voltage will not exceed the sum of output terminal voltage
and the difference voltage.
When Sense is reversed or short-circuited, the voltage meter value is dis-
played as a positive/negative value close to 0, and abnormal high voltage
output does not occur, which can avoid damage to the DUT.
