Chapter 6 Measurements
Use the selected network to select any current range (AC, DC, AC + DC, AC peak) and any measure-
ment range (50 A, 500 A, 5 mA, 50 mA).
1. Connect the instrument and the equipment under test.
See "3.3 Connecting equipment under test to the instrument" (p. 36)
2. Connect test leads to terminals T1 and T2.
3. Position the tip of the test lead on the enclosure of the equipment under test.
4. Free current measurement starts upon return to the measurement screen.
Measurement conditions can be changed during measurement.
Free current measurement (Enclosure - Enclosure)
• Conduct leakage current measurement between enclosure and enclosure
using two ungrounded locations on the enclosure.
• The terminal block is not used for internally powered equipment.
• When the protective grounding wire is disconnected (single fault), a protec-
tively earthed enclosure is handled as a non-protectively earthed enclosure.
• Free current measurement does not permit automatic measurements.
