*It is not possible to select a current less than 10 A but since the open
circuit terminal voltage is somewhere between 2 V and 5 V (if input power
is 100 V to 250 V), actual test current can be as low as 2 A when loop
resistance is 1
Ω
. If actual current is less than 2 A a ‘Current loop fail’ will
be reported.
