4: Beginning of Loop (P87)
1: 0
Delay
2: 8 Loop Count
;Square La/L to convert to dielectric constant:
;Note: The user must manually allocate 8 input locations "WC_1" through WC_8".
5: Z=X*Y (P36)
1: 1 -- X Loc [ LaL_1 ]
2: 1 -- Y Loc [ LaL_1 ]
3: 11 -- Z Loc [ WC_1 ]
;Multiply the dielectric constant by 0.1 to prepare for the 3rd order polynomial
;with the appropriately scaled coefficients for Topp's calibration:
6: Z=X*F (P37)
1: 11 -- X Loc [ WC_1 ]
2: 0.1 F
3: 11 -- Z Loc [ WC_1 ]
;Apply Topp's 3rd order polynomial:
7: Polynomial (P55)
1: 1 Reps
2: 11 -- X Loc [ WC_1 ]
3: 11 -- F(X) Loc [ WC_1 ]
4: -0.053 C0
5: .292 C1
6: -0.055 C2
7: 0.0043 C3
8: 0.0 C4
9: 0.0 C5
8: End (P95) ; End of the Loop.
;Measure the datalogger power supply voltage:
9: Batt Voltage (P10)
1: 19 Loc [ Bat_Volt ]
;Set the Output Flag to output data each time measurements are made:
10: Do (P86)
1: 10 Set Output Flag High (Flag 0)
;Output a time stamp; year, day, and hour/minute:
11: Real Time (P77)
1: 1220 Year,Day,Hour/Minute (midnight = 2400)
;Output the 8 water content measurements and battery voltage:
12: Sample (P70)
