Continuous Data Streaming

On power up, after the initial 60-second heater delay, the Mini-OX will automatically begin outputting the measured O₂ concentration and sensor t_d as both an averaged and raw value.

The averaged values give a stable output with the amount of averaging user variable while the raw un-averaged values allow the user to detect sudden oxygen changes.

 

The averaged value is the measurement output on both the 4 – 20mA and 0 – 10V_DC outputs. The sensor t_d value is the measure of the partial pressure of oxygen in the measurement gas. The O₂ concentration (%) is the t_d value scaled by the stored calibration value.

To stop or restart the data streaming:

 

1. Connect the Mini-OX via the RS232 interface to the PC.

2. Type “S” (not case sensitive).

   NOTE: Data streaming automatically ceases during calibration.
