• Verifying the three probe configurations of the instrument (G-L, PH-L and PH-PL) are functioning properly. The LVB-2 consists of loads based on the 132V/264V test voltages and failure limits listed in the IEC60601-1 test standard for different types of leakage tests.

LVB-2 Instruction Sheet The LVB-2 load box consists of resistors designed to induce a PASS FAIL condition: • The Check Point knob position determines which resistor is set in the LVB-2 • Each check point has a PASS and FAIL condition.
Test Setup To setup a test, connect the DUT outputs (L, N and G) of the leakage instrument to the line cord connector on the LVB-2. The two probe connections will also need to be made between the instrument and the LVB-2 for the verification of additional leakage test types Program a test sequence based on the parameters listed on the test box for each load type.
