;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)
