Good Day Everyone,

I created two DataTable to store the readings for T107 temperature probe at different interval, there is a 0.01 to 0.03 degree different in the readings store in the two table at the same timestamp.   

TIMESTAMP, RECORD, batt_volt, PTemp, T107_C_Avg

26/3/2025, 17:18, 1, 12.05, 25.34, 25.02 @2 minutes DataTable

26/3/2025, 17:18, 4, 12.05, 25.34, 24.99 @6 minutes DataTable

'''DataTable1 to store records for every scan interval

DataTable (Table1,1,-1)

Sample (1,batt_volt,FP2) 

Sample (1,PTemp,FP2) 

Average (1,T107_C,FP2,0) 

EndTable

'''DataTable_2

DataTable (Table2,1,-1) 

DataInterval (0,6,Min,10) 'Store every 6 minutes 

Sample (1,batt_volt,FP2) 

Sample (1,PTemp,FP2) 

Average (1,T107_C,FP2,0) 

EndTable

BeginProg  

 Scan (2,Min,0,0)'Scan interval   

PanelTemp (PTemp,250)   

Battery (batt_volt)    

Therm107 (T107_C,1,3,Vx1,0,_60Hz,1.0,0)

 CallTable Table1

 CallTable Table2

EndProg

Anyone can help me on this. Thanks.

Regards,

That is an average in the processing of the data table. The first table has no data interval, so it is an average of just the most recent reading. The second table is the average of the last 6 minues of readings (3 values). It is expected to see a small difference if temperature changed at all.

Thanks JDavis.

I replaced to " Sample", reading is fine now. 

Thank you.
