6.3 Analog output
For the attachment of recorders or integration systems, the 732 IC De-
tector offers the two analog outputs 11 11 (0 … 1 V) and 12 12 (0 … 10 mV)
(see section 3). The attachment of these instruments is described in
detail in section 2.9. The polarity of the output signal at the analog out-
put sockets can always be switched under the key (see
section 4.5.1). The circuit of the two analog outputs has the following
appearance:

6.4 External power supply for
733 IC Separation Center
If the 733 IC Separation Center is operated without the 732 IC Detector,
an external power supply must be attached to connection 48 48 "External
Power". Power supply and connecting cable must comply with the fol-
lowing conditions:
