Vaisala Indigo 201 - Calibration PIN Code; Restoring Factory Adjustment

5.3 Clearing Analog Output Settings from
Indigo
If you need to restore Indigo 201 to a state where no analog output configuration exists in
the transmitter, you can clear the current configuration from the Settings > General menu.
When you remove the analog output configuration from Indigo, Indigo automatically
adapts the analog output settings of the next probe that you connect.
To clear the configuration:
1. Launch the Indigo 201 wireless configuration interface.
2. Open the Settings > General menu.
3. Go to the Reset > Clear Analog Output Settings section and select Clear.
5.4 Analog Output Overrange Behavior
The analog output of the probe has a defined behavior when the values measured by the
probe are outside the scaled analog output range. At first, the output is clipped when the
measurement exceeds a set limit (the measurement continues, but the output does not
change from the clipped value).
When the measurement exceeds the second limit (error limit), the analog output switches to
the error state
defined for the output.
The same clipping and error limits are applied when the measured value drops back to the
scaled range: at first the output returns to the clipped value from the error state, and then to
normal output.
5.4.1
Analog Output Overrange Example
Consider a probe with 0 ... 5 V output, scaled to 0 ... 200 000 ppm (= 0 ... 20 %) CO
2
.
• When the measured CO
2
rises above 20 %, the output rises above 5 V.
