solar panel voltage analysis


Taurai Dec 26, 2018 01:35 PM

I am trying to read voltage and current from a 60w solar panel  as well as solar radiation over a period of 1 week ,i need advice of how i can set up using cr 10 x data logger 

I have written a sample program to measure voltage of a 1.5V battery jst to test the program but i dont seem to get any readings (test program below)

;sample program to measure voltage *Table 1

Program 01: 20.0000 Execution Interval (seconds)

1: Volt (SE) (P1)

  1: 1 Reps

  2: 15 2500 mV Fast Range

  3: 1 SE Channel

  4: 1 Loc [ voltage ]

  5: 1 Multiplier

  6: 0.0 Offset

2: If time is (P92)

   1: 00 Minutes (Seconds --) into a

  2: 10 Interval (same units as above) 

  3: 10 Set Output Flag High (Flag 0)

3: Set Active Storage Area (P80)  

  1: 1 Final Storage Area 1

  2: 1 Array ID

4: Real Time (P77)

  1: 1220 Year,Day,Hour/Minute (midnight = 2400)

5: Average (P71)  

  1: 1 Reps

  2: 1 Loc [ voltage ]

6: Sample (P70)

  1: 1 Reps

  2: 1 Loc [ voltage ]

7: End (P95)

*Table 2 Program

  02: 0.0000 Execution Interval (seconds)

*Table 3 Subroutines

  End Program

kindly advice on the steps needed ,Am getting the End without if loop error

Be sure you connected the positive of the battery to SE1 on the datalogger and the negative end to analog ground of the datalogger.

Okay will try to do that ,does the program look okay because am getting the End if /loop error
