2.896.0030 896 Professional Detector – Conductivity & Amperometry
4 Start-up
The 896 Professional Detector – Conductivity & Amperometry is set to
work together with the IC instrument. Additional information can be
found in the Start-up chapter in the manual for the IC instrument.
The following tests and installation tasks must be performed during the
first start-up of the IC device with the 896 Professional Detector – Con-
ductivity & Amperometry.
4.1 Instrument test with dummy cell
When you are putting the 896 Professional Detector – Conductivity &
Amperometry into operation for the first time, or when problems occur
which may be caused by signal recording or signal transfer, we recom-
mend to test the electronics and the connection to the PC using the
dummy cell (6.2813.040).
Proceed as follows:
Testing with the dummy cell
Preconditions:
￭ In order to achieve accurate results, we recommend that the lid be
closed during the instrument test with the dummy cell. Since the space
under the front lid is rather limited, we further recommend to remove
the measuring cell from the cell holder for the instrument test with the
dummy cell.
For the instrument test you require:
￭ The dummy cell (6.2813.040)
￭ The electrode connection cables (6.2165.000)
1 Connect the electrode connection cables to the dummy cell
￭ Plug in the angled plug of the working electrode connection cable
(labeled with WE) into the WE socket.
￭ Plug in the angled plug of the reference electrode connection
cable (labeled with RE) into the RE socket.
￭ Plug in the angled plug of the auxiliary electrode connection cable
(labeled with AE) into the AE socket.
2 Connect the electrode connection cables to the detector
(unless they are already connected)
