Testing the anode earth current with an anode tester
Note
We recommend that the magnesium anode function is checked annually. This
function test can be carried out without interrupting operation, by measuring the
earth current with an anode tester.
1.
Remove cover
A
.
2.
Pull earth lead
B
from tab
C
.
3.
Connect the tester (up to 5 mA) in
series between tab
C
and earth
cable
B
.
&
The anode is OK if the indicated
current is > 0.3 mA.
&
Visually inspect the anode, if the
current measures < 0.3 mA or if
there is no current at all (see
page 23).
