Press arrow until black box surrounds the current input parameter
Press arrow and select “external shunt”
Press “ENTER”, external shunt will now be selected
Press arrow until black box surrounds the shunt parameter
Manually input the shunt resistance value
Press “ENTER”, external shunt value will now be selected
If connecting the external shunt to a different channel then use the arrow to
select the correct channel configurations screen as prompted at the bottom of
the “RANGE” home screen
Now going back to the real time
display screen the range selected by
the analyzer is the (300mV) range.
This range is a peak range and the
analyzer will convert this voltage to
the equivalent current range,
dependent upon the shunt value
entered in the “RANGE” menu. In this
case the shunt value is 470mΩ;
therefore the analyzer will display
638.3mA for the 300mV range
I =
As the instrument ranges up and down the Arange value will change respectively
HF100, HF200 and HF500 Current Shunts
