6.2 Configuring analog outputs with Indigo80
handheld indicator
6.2.1 Analog output configuration overview
The transmitter has 3 analog outputs that can be configured with the Indigo80 handheld
indicator. Each output has the same set of configuration options in the Devices > Settings
menu of the indicator.
The available selections depend on the probe that is connected to the transmitter
(for example, CO
2
output parameter selection is only available for CO
2
probes).
The
Analog output type selection in the Settings menu defines whether the outputs are used
for voltage or current output. When you change the output type, Indigo80 reloads the
transmitter.
6.2.2 Analog output configuration example
This example shows how to use Indigo80 to configure the transmitter's analog output 1 to use
the following settings when a humidity and temperature probe is connected to the transmitter:
• 4 ... 20 mA current output
• Relative humidity measurement scaled to 0 ... 100 %RH
• Clipping limit 5 %, error limit 10 %, and error output 3.6 mA
1. Connect the transmitter to the indicator.
2. Open the main menu by pressing
.
3. Select Devices. If you have more than one device connected to the indicator, make a
further selection between the devices.
In this case, select Indigo300.
4. Select Settings.
5. In Analog output type, select Current output.
6. In Settings, scroll down and select Analog output 1.
7. In Output mode, select 4...20 mA.
8. In Output parameter, select Relative humidity.
9. Select Scale low end. Use the arrow buttons to set the value as 0.00, and then select Set.
10. Select Scale high end. Use the arrow buttons to set the value as 100.00, and then select
Set.
11. Select Error output level. Use the arrow buttons to set the value as 3.60, and then select
Set.
12. Select Clipping limit. Use the arrow buttons to set the value as 5.0, and then select Set.
