±5%. This current can be limited in SET-UP, to between 0.2 and 5mA. It can also be limited
by the maximum output power, which is 10W.
The limit acts whatever the type of test:
the power limit for Burn-in tests,
and the current limit for the Break at I-Limit and Early break tests.

Maximum resistance measured = to be interpolated from the values in the tables of fixed test voltages above.
The intrinsic uncertainty depends on the test voltage and on the resistance measured. It can be interpolated from the tables of
fixed test voltages.
