CMP6-L, CMP11-L, and CMP21-L Pyranometers

Wiring for the example is given in TABLE 7-9.

TABLE 7-9. CR10X Wiring for CMP6 Example Program

Wire Color Description CR10X Jumper*

White Solar Signal (+) 1H

Black Solar Signal (–) 1L

Clear Shield AG

* Jumper 1L to AG terminal on CR10X with user-supplied 26 AWG or larger

wire.

;{CR10X}

*Table 1 Program

01: 10.0000 Execution Interval (seconds)

; CMP6 measurement in W/m2

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)

1: 3 X Loc [ Solar_Wm2 ]

2: 4 <

3: 0 F

4: 30 Then Do

3: Z=F x 10^n (P30)

4: End (P95)

; Calculate units in MJ, where MJ = m * t * 0.000001.

; m = Solar_Wm2 from above, and t = 10 (scan interval).
