Notes to figures in fig. 35:
"cal temp." will only be displayed if
temperature measurement or temperature
(1)
compensation has been switched on in the
"setup" menu.
"cal pH" will only be indicated if pH
(2) measurement or pH compensation has
been switched on in the "setup" menu.
"controller" will only be displayed if a
controller has been selected and
(3)
configured in the "setup" menu and in the
"main menu"..
"water sensor" will only be displayed if
(4) measuring cell AQC-D2/-D12 has been
selected in the "setup" menu.
"CalData/LogBook" will only be displayed if
(5)
a calibration has already been made.
service
chlorine
test current
test relay
In the "service" menu, the following items are listed:
• "measured value": displaying data of the previous
ten calibrations
• "controller": checking controller settings
• "test current": testing the functioning of the
current outputs
• "test relay": testing the functioning of the relays
• "test display": testing the functioning of the
display.
"measured value": logbook registration of
calibration data
The calibration data of all activated measuring
values are registered in chronological order by a
logbook function (exception: redox measurement!).
Example: With pH measurement, the logbook lists
the following data:
• calibration number with date/time
• slope (sensitivity of the electrode)
• asymmetric potential of the electrode
• temperature of the buffer solution used
• calibrated measured value.
Under "measured value", the following data are
displayed:
• current measured value
• current cell voltage or cell current.
42
Under "water sensor" the following data are
displayed:
• speed of the water sensor during the last
calibration
• actual speed of the water sensor.
"controller" (checking controller settings)
1. Depending on the configuration, select relay 1,
relay 2 or continuous controller using the [Up]
and [Down] buttons, and press [OK] to switch to
the corresponding menu.
– In the first line, the configured type of controller
is displayed, and in the subsequent lines the
current controller settings are listed.

"test current" (testing the functioning of the
current outputs)
1. Select the current output to be tested using the
[Up] and [Down] buttons, and press [OK] to
switch to the corresponding menu.
Depending on the configuration of the current
outputs, the current outputs can be switched on with
the following current values, and the current value
can be output to the system:
• test currents of 0, 10, 20 mA with selected
standard range 0-20 mA
• test currents of 4, 12, 20 mA with selected
standard range 4-20 mA or with freely adjusted
current outputs.
2. Select the current values using the [Up] and
[Down] buttons.
– When a line is selected, the state of the current
output with the corresponding value is
automatically set to on.
– As soon as another line is selected, the
previous current value is automatically
switched off, and the new current value is set
to on.
"test relay" (testing the functioning of the relays)
1. Select the relay to be tested using the [Up] and
[Down] buttons, and press [OK] to switch it on or
off.
– If either of the lines "relay 1" or "relay 2" has
been selected, the relay that was the last one
activated before entering the test menu is
switched off. Considering the current alarm
values and controller values, the relay is
switched on again when the test menu is left.
"test display" (testing the functioning of the
display)
• If the display turns completely dark: The display
functions OK.
• If the display stays partly bright: The display is
faulty.
• Press [OK] to leave the test menu.
