Use the service menu to read all important settings
and to check instrument functions. In the code menu,
the service range covers codes 50-57.
Code 50
• Display of raw data values of cell
– Actual cell current in µA (Conex
– Actual cell current in mV (Conex
Code 51
• Display of calibrated gradient of current (last)
calibration.
®
– In µA/ppm (Conex
®
– In mV/pH (Conex
system selected).
®
• Not used with Conex
system selected.
Code 52
• Display of calibrated
– asymmetry potential with pH sensor system
– redox offset with redox sensor system
• Only used with Conex
Code 53
• Display of temperature in °C with temperature
sensor (Pt100) connected
• Only used with Conex
Code 54
• Display of water sensor depending on selected
type of measuring cell.
– AQC-D1/-D11/-D3/-D13:
Display 100 % = water present
Display 0 % = water missing

Test routine, checking of various instrument
functions:
5500: Test of control relay: relay switches,
flashing display of code. To return to code
level, press [OK].
5501: Test of alarm relay: like 5500
5502: Test of current output: 4 mA are displayed
at the current output, flashing display of
code. To return to code level, press [OK].
5503: Like 5502, except that 20 mA is displayed.
5504: Display test:
If the screen is completely darkened: the
display is OK.
If the screen remains partially bright: the
display is faulty.

Code 56:
• Setting of display contrast between 0 % and 100
%.
Code 57:
• If a controller has been parameterised, the
current controller performance (y-out) is
displayed in %. Controller stop must not be
activated in the process.
• The display is 0.00 % if a controller has not been
parameterised.
