6.12. LEAKAGE CURRENT (ILEAK)
The instrument allows the measurement of the AC leakage current both with the use
of a transducer clamp (optional accessory HT96U) connected to the ILEAK input (see
Fig. 2 - part 26) and on equipment directly connected to the schuko test socket on the
front panel (see Fig. 2 - part 25). In this case the instrument powers the UUT and
measures the leakage current on the plug.
1. Press the
FUNC key and select the ILEAK function. The following screen is
shown on the display

2. Select the test parameters on the instrument (see Table 13) and carry out the
desired setup

3. Select CLAMP mode by pressing the
MODE touch-screen key first
4. Check selected measurement range and modify it if needed by pressing the
RANGE touch-screen key first
5. Check selected limit leakage current by pressing the LIMIT touch-screen key first.
Four independent limit values are available for quicker operations. Select the
closest one and modify it by using the
+ and ʊ touch screen keys if needed
6. Select measurement screen by pressing the touch-screen key and check all
settings again
7. Connect the current clamp to measured wiring according to the
