1: Volt (Diff) (P2)
1: 1 Reps
2: 23 25 mV 60 Hz Rejection Range ;use the 50 mV range for the CR7, 21X and CR23X
3: 1 DIFF Channel ;use the 250 mV range for the CR10X if
4: 3 Loc [ Solar_Wm2 ] ;calibration factor is > 25 µV/Wm-2
5: 69.7837 Multiplier ;1000/14.33
6: 0 Offset
; Set negative values to zero
2: If (X<=>F) (P89)
