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 navigate between
configurable parameters. Once a parameter is selected, its setting can be selected per the follow-
ing 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 blank)
Alarm Value: 3.6 mA, 22.0 mA or Off (default is off)
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
value 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.
