6.2
Measuring Resistance to ground R
g
or R
gp
according to
IEC 61340-4-1
(e.g. for measuring flooring systems, table mats, chairs etc.)
➭
Connect the red measurement cable from the “+ Pole” to the
measuring electrode.
➭
The black, shielded measurement cable with the double
“COM / SHIELD” connectors is connected to protective earth
when measuring R
g
, or to a groundable point when measur-
ing R
gp
.
Note
Use only the 2-pole measurement cable.
➭
Select a measuring voltage of U
M
= 10 V in the Resd switch
position. If a value of less than 1 M
is displayed, this value is
the result.
➭
If the resistance to ground Resd
1 M
is displayed with the
10 V measuring voltage, the 100 V measuring voltage must
be selected. The value which is then displayed is the result.
