8.3 Analog outputs
(PATH: Menu / Configure / Analog Outputs)
Enter Configuration mode as described in Section 8.1. “Enter Configuration Mode” and navigate
to the menu “Analog Outputs” by using the or . key.
Press the [ENTER] key to select this menu, which lets you configure the 4 analog outputs.
Once analog outputs have been selected, use the and c buttons to buttons to navigate
between configurable parameters. Once a parameter is selected, its setting can be selected per
the following table:
When an alarm value is selected (see chapter 8.5.1 “Alarm”;
PATH: Menu/Configure/Alarm/Clean/Setup Alarm),
the analog output will go to this value if any of these alarm conditions occurs.
Parameter Selectable Values
Aout: 1, 2, 3 or 4 (default is 1)
Measurement: a, b, c, d or blank (none) (default is a)
Alarm Value: 3.6 mA, 22.0 mA or Off (default is off)
h
NOTE: Beside the measurement values pH, O2, T, etc. also the ISM values DLI, TTM and ACT
can be linked to the analog outputs if they have been assigned to the corresponding line in the
display (see chapter 8.2.1.2 “ISM sensor”)
The Aout type can be Normal, Bi-Linear, Auto-Range or Logarithmic. The range can be 4–20 mA
or 0–20 mA. Normal provides linear scaling between the minimum and maximum scaling limits
and is the default setting. Bi-Linear will also prompt for a scaling value for the mid-point of the
signal and allows two different linear segments between the minimum and maximum scaling
limits.
Enter the minimum and maximum value of Aout.
If Auto-Range was selected then Aout max1 can be configured. Aout max1 is the maximum val-
ue for the first range on auto-range. The maximum value for the second range on auto-range
was set in the previous menu. If Logarithmic Range was selected, it will also prompt for the
number of decades as ”Aout1 # of Decades =2”.
The value for the Hold mode can be configured to hold the last value or can be set to a fixed
value.
