1)
Select the R
A
measurement by pressing the
FUNC
hard key first.
2)
Check selected nominal differential current (10, 30, 100, 300, 500, 650 and 1000 mA) and modify it
if needed by pressing the
I
N
(6) touch-screen key first.
3)
Select measurement screen by pressing the
(5) touch-screen key and check all settings again.
4)
Connect the test leads according to one of the figures below. READY message (3) will appear
when mains voltage U
L/PE
within 100 ... 265 V is present.
