2.4.5 Application examples
The 731 Relay Box is controlled via remote lines which can be freely
selected in many Metrohm instruments and set to be operation-
controlled.
On the 731 Relay Box an output line must be
set for each switchable output; this then con-
trols the corresponding output. This is done
with the remote address selection disk on the
front of the relay box. Use a screwdriver to set
the corresponding number of the output line.
