8.3 Analog Outputs

(PATH: Menu/Conﬁgure/Analog Outputs)

Enter conﬁguration mode as described in Section 8.2

Press the [ENTER] key to select this Menu, which allows conﬁguration of the Analog Outputs

Two Analog Outputs are available for single channel transmitters and 4 on four channel units.

Once the analog outputs have been selected, use the  and  buttons to navigate between

conﬁgurable parameters. Once a parameter is selected, its setting can be selected per the

following table:

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 of Off (default is off)

* Aout 3 and 4 available on two-channel units only

When an Alarm Value is selected, the analog output will go to this value if any alarm condition

occurs

The Aout type can be Normal, Bi-Linear, Auto-Range or Logarithmic. The range can be 4–20mA

or 0–20mA. 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.

Pressing the [ENTER] key again will bring up the Save Changes dialog. Selecting No will

discard the entered values and return to the measurement display screen, selecting Yes will save

changes made.
