Data field description:
Date(yyyy/MM/dd): date.
Time(hh:mm:ss): time.
‐ Timebase: timebase – units in seconds.
Ref1, Sen1Ch1, Sen2Ch1…: are the raw signal Reference (Ref), Sense 1 ( Sen1) and Sense 2 ( Sen2) values form which the BC concentrations are calculated for channel 1 (Ch1), that is wavelength 370 nm. BC11 is the uncompensated BC calculated from the spot 1 for channel 1. BC1 is the final results the BC calculated form measurements for channel 1 (370 nm).
Flow1; Flow2; FlowC: Measured flow in ml/min. Flow 1 is flow through the spot 1, Flow_C is common (total flow) through the optical chamber, Flow_2 is the difference between these two.
Pressure (Pa); Temperature (°C); RH (%): These are the pressure and temperature which the instrument uses to report flow. By chosing to report mass flow, (101325 Pa, 21.11 C) are used to convert the measured mass flow to reported volumetric flow at these conditions (these are values used by the flow meter in the AE33). These values can be substituted for any other (pressure, Temp) values, should you want the flow to be reported at 0 C, or 25 C for example. Optionally, you can choose volumetric flow at ambient conditions to be reported. To do that you need an optional weather station accessory for the (pressure, Temp) measurement. We offer this separately (PN DU00000200). This external device is connected to the COM ports, please see below.
‐ ContTemp; SupplyTemp: control and power supply board temperatures
Status; ContStatus; DetectStatus; LedStatus; ValveStatus; LedTemp: status codes for the instrument, reported in the , please see manual, chapter 5.2. and the subcomponents: controller, detector LED board; valve status (each valve can be on or off); LED board temperature
