Hi.

I have recently bought a new DT80W-4 and started using the dEX-2 software for programming and downloading logged data.

I have one schedule running where signals from three load-cells and a thermocouple are recorded. The signals from the load cells are in mV and I convert it to kg by multiplying by a fixed factor.

The first columns in the csv-file become Timestamp and TZ as expected. However, all the remaining columns have the same heading namely Mass_1 (kg). The logged data below the headings are clearly from the other load cells and the thermocouple.

The display on the logger shows the correct name. Also when I load the Schedule Tree, the channel names are correct.

What have I missed?

Update: If I download the data as DBD-file and use DPlot to import and plot it, the column headings seems correct. And they remain correct after saving the file to csv-format in DPlot.

I feel this is not a proper way. There must be some error in the logger. But what? Is there anybody who have had similar experience?

Hi Martin,

I am not 100% sure with your case, did you try to download multiple schedules into a single file? If yes, perhaps you can read this explanation.

When you download the logger data, the default setting will put all schedule data into one CSV file. Normally each schedule will have their own separate interval thus must be downloaded separately.

When you download in one file, you will see header from all schedules but the data itself will appear according schedule sequence from A to K.

Example:
In this example I took 3 data from each schedule.

"Timestamp","TZ","PPA (L/sec)","CalcPPA (L/sec)","CalcPPA_10 (L/sec)","PPFlume AV (m)","PPO AV (l/min)","PPA AV (L/sec)","PPF AV (L/sec)","Dam AV (L/sec)","PPFlume AV_10min (m)","PPO AV_10min (l/min)","PPA AV_10 (l/min)","PPF AV_10 (l/min)","Dam AV_10 (l/min)","PPF (L/sec)","CalcPPF (L/sec)","CalcPPF_10 (L/sec)","Dam (L/sec)","CalcDam (L/sec)","CalcDam_10 (L/sec)"

But if my assumption was not correct can you send me some data sample?

Hi Rudy.

Thank you for the reply.

The data is generated from a single schedule.

I think the problem is in that specific Datataker (hardware, or firmware). When I use the same dxc-file in an other DT80-4 logger (mine is a DT80W-4), the headings in the csv-file are correct.

Martin

Hi Martin,

The logger setting may affect the appearance of header, can you please try to reset all logger setting to default by sending FACTORYDEFAULTS and try it again?

Best regards,
Rudy Gunawan
