Figure 15 Analog output type (current or voltage) selection
Receiving analog output settings automatically from probe
The transmitter can receive the analog output settings automatically from the connected
probe in the following cases:
1. The transmitter is a new unit and has not been configured yet.
2. The user has removed the analog output configuration from the transmitter.
It is recommended to always review the analog output settings with the Insight
PC software after connecting a probe.
5.2 Analog output configuration example
This example shows how to configure analog output 1 to use the following settings when a CO
2
probe is connected to the transmitter:
• 4 ... 20 mA current output
• Carbon dioxide measurement scaled to 0 ... 20 %CO
2
• Clipping limit 5 %, error limit 10 %, and error output 3.6 mA
1. Connect the transmitter to the Insight PC software.
2. Select
and open the
Configure Device
menu.
3. Open the
General

device menu and select one of the 3 analog outputs.
5. Select
4 ... 20 mA
from the
Output mode
dropdown.
6. Select
CO2
from the
Output parameter
dropdown.
Set the scaling according to the unit (for example, ppm or %CO
2
) selected in
the
Settings > Unit Settings
menu in the Insight main view. The example here
uses scaling for %CO
2
.
7. Type
