values set on base of selected protective circuit breakers. The measurement complies
with requirements of the standard EN 61557-3.

MI 3321 checks voltages on TP1 before running test and disables test in
case hazardous live voltage is detected on TP1 PE. In this case,
immediately remove supply from test circuit, find and eliminate problem
before any other activity!
