Caution
T1/T2/T3
Te rm i na l s
If network B (MD B) is selected an isolation
transformer that outputs 110% of the rated voltage
specified for the EUT is required. The neutral line
must be grounded (from the secondary side of the
transformer).
Measurement networks (MD)A, B, C all require an
isolation transformer.
1. Insert the test leads to one of the terminals
2. The measuring mode determines which
terminal will be used.
Terminals T1, T2 and T3 are shown above.
Warning: To avoid the risk of electric shock, do not
touch the tips of the test leads when operating.
Foil Probe
1. The foil probe is used to measure the surface
leakage current (touch current) of the EUT.
Attach the probe metal-foil-side down onto the
enclosure of the EUT.
2. Attach the test leads to the foil probe using
alligator clips to the area on the right, as shown
in the diagram

The arrow above shows the contact point for the test
lead.
Alligator Clips
1. Plug a test lead into the rear panel.
2. Use an alligator clip to clip to the metal foil or
to other points under test.
The arrow mark indicates the
location that the test lead and
alligator clips are clipped
together.
