The next setting, Tau (down), is the tau value for calculations while the measured gas concentration is decreasing.
Increasing the Tau (down) reading increases the transmitter’s response speed.
5.8 LabCal Outputs?
The LabCal Outputs? option enables you to calibrate (or trim) the analog outputs. After you select the output (A or B)
to calibrate, the output is driven to 20 mA. You can input the actual output value (as shown by a multimeter or
connected control device) and adjust the output. The output is then driven to 4 mA, and you can make a similar
adjustment.
