;CNR1 sensitivity for program example = 7.30 uV/W/m^2

;Multiplier for measurement instructions = 1000/7.3 = 136.99

*Table 1 Program

01: 2 Execution Interval (seconds)

;Measure CM3 Up and CM3 Down (shortwave radiation)

;Note: Multiplier (Parameter 6) will be different for each CNR1

1: Volt (SE) (P1)

1: 2 Reps

2: 22 50 mV, 60 Hz Reject, Slow Range

3: 1 SE Channel

4: 1 Loc [ CM3_up ]

5: 136.99 Mult ; mult = 1000/CNR1 sensitivity

6: 0 Offset

;Measure CG3 Up and CG3 Down (longwave radiation)

;Note: Multiplier (Parameter 6) will be different for each CNR1

2: Volt (SE) (P1)

1: 2 Reps

2: 21 10 mV, 60 Hz Reject, Slow Range

3: 3 SE Channel

4: 3 Loc [ CG3_up ]

5: 136.99 Mult ; mult = 1000/CNR1 sensitivity
