9. Service and maintenance
Extract the screw. Remove the cable hood 
with the socket insert  from the cable socket
base  and thus separate the pressure gauge
EN
from the power supply.
Remove the cable hood cover  from the
cable hood  and push the socket insert  out
downwards through the entire cable hood .
Use a short stranded wire with bare points at
both ends (max. permissible resistance 30 Ω)
to bridge contacts 5 and 6 on the socket insert.
Reassemble the plug in reverse order. Place
the plug, with the attached piece of stranded
wire, onto the pin insert , and thus reestablish
the power supply.
Within a max. 30 seconds the new zero point
will be stored within the electronics. During this
period, the current in the loop will increase to
9.5 mA.
The new zero point also remains stored in the
case of a power failure.
Loosen the plug again in the same sequence
as described above and remove the piece of
stranded wire. After reassembling the plug,
the electrical output signal will once more
correspond to the indication of the mechanical
pointer.
