5.7.3. RA MEASUREMENT

Measured quantities and display ranges:

Global earth resistance RA 0  2.000  (IN = 10 or 30 mA)

0  1.000  (IN = 100 mA)

0  300  (IN = 300 mA)

0  200  (IN = 500 mA)

0  150  (IN = 650 mA)

0 100  (IN = 1000 mA)

Mains voltage UL/PE 100  265 V AC

Contact voltage UC 0  100 V AC (UC LIM = 50 V)

0  50 V AC (UC LIM = 25 V)

Input requirements:

Mains voltage UL/PE (READY condition) 100  265 V AC

1) Select the RA 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 UL/PE within 100 ... 265 V is present.
