2 Unscrew the fastening screw from the reference electrode holder.
Push the fastening screw over the cable of the Ag/AgCl reference
electrode.
3 Check whether the sealing ring is seated on the reference electrode
and insert the reference electrode into the reference electrode
holder.
4 Tighten the reference electrode to the reference electrode holder
with the fastening screw.
Further information regarding the correct handling of the Ag/AgCl refer-
ence electrode can be found in the leaflet for the Ag/AgCl reference elec-
trode.
3.3 Connecting the detector capillaries
The amperometric detector is equipped with a preheating capillary in its
interior to ensure that the eluent flows through the measuring cell at a
constant temperature.
Connecting the preheating capillary is optional. If the ambient conditions
are optimal or if the eluent is heated in the column, then the measuring
results can be sufficiently accurate, even without the use of the preheating
capillary.
CAUTION
The preheating capillary may not be connected if highly flammable liq-
uids are analyzed!
In the event of a leak, the fluid might evaporate and ignite in the heat-
ing area.
If the preheating capillary is not used, proceed as follows:

1 Connecting the cell inlet
Use a pressure screw (6.2744.014) to fasten the detector input capil-
lary to the In connector of the measuring cell.
