I bought the device Velleman K8047 from Egypt and I want to know if I could use it to record the DC voltage every 1 or 2 or 10 sec and not every 1/100 sec. Also, I want to record the DC voltage for 1 hour. Could you please tell me how could I do that? Knowing that the device records only 1000 records in the data sheet.
Find down the data sheet which I recorded it. I want to know what the columns No. 2 (CH1) and No. 6 (CH1/ V) represent? And what the value 255 (where CH1: 255= 30V) represent.
Best regards.

[quote]I could use it to record the DC voltage every 1 or 2 or 10 sec and not every 1/100 sec.[/quote]Select Time/Div range 100s to record sample enery 1 sec. Select 200s to record sample every 2 sec and 1000s to record sample every 10s.
You’ll see the sample rate on the top right corner of screen.

[quote]Also, I want to record the DC voltage for 1 hour.[/quote]To save the recorded data of any length you can use File -> AutoSave Data.

[quote]I want to know what the columns No. 2 (CH1) and No. 6 (CH1/ V) represent?[/quote]In the column 2 there is the recorded ‘raw’ Analog-to-Digital converter output 8bit data (range 0 to 255). Column CH1/ V shows the DC voltage applied to input channel CH1.

[quote]And what the value 255 (where CH1: 255= 30V) represent.[/quote]This indicates the selected voltage full scale range.
