light.
2.3 Attaching the accessories
2.3.1 Connection of detector block
The metal-free 1.732.0110 Detector block belongs to the scope of
supply of the 861 Advanced Compact IC; it must be inserted in the in-
strument and connected up. Proceed as follows:
If the detector block needs to be replaced then the cell constant of
the new one must be entered. On the rear of the detector block the
cell constant measured in the factory is printed on: c = XX.X /cm. This
value should be entered in the software (see Cap. 3.3.2) in order to
ensure that the conductivity is displayed accurately.
1 Install detector block
• Unscrew the four knurled screws 13 from the top rear panel
14 of the 861 Advanced Compact IC and remove rear panel
(see Figure 2)
• Position detector block 45 from the back in the space pro-
vided in the 861 Advanced Compact IC and push fully to the
front (see Figure 3, Figure 4 and Figure 5).
• Insert the cable permanently attached to the detector block
45 in one of the openings 12 and the outlet capillary in one of
the openings 8 of the rear panel 14.
You can now place the 853 CO
2
Suppressor beside the de-
tector block of Version 2.861.0040 so that you do not have to
remove the rear panel again (see Figure 5). Connecting the
853 is described in detail in Section 2.9. Pull the Remote ca-
ble and the mains cable out of opening 11 in the rear panel.
2 Replace rear panel
• Replace rear panel 14 and screw onto the 861 Advanced
Compact IC using the four knurled screws 13.
3 Connect detector block
• Plug the gray connecting cable permanently attached to the
detector block 45 into connection 22 "Detector Block" of the
861 Advanced Compact IC and fasten to the instrument by
tightening the screws in the cable connector (see Figure 2).
4 Connect waste container
• Lead the outlet capillary of the detector block 45 to a suffi-
ciently large waste container and fix in place.
