Copy range code options from example 1 here:

* Proper entries….

* Proper entries will vary with program and input channel usage.

** 25 mV range for CR10X, 50 mV for 21X and CR7

*** 4200 mV for 21X and CR7, 2100 mV for CR10X

+ 25 mV range for CR10X, 50 mV for 21X and CR7

++ 7.5 mV range for CR10X, 5 mV for 21X and CR7

7. Calibration

The CNR1 should be recalibrated every two years, or as an alternative, by

letting a higher standard run parallel to it over a two-day period and then

comparing the results. For comparison of pyranometers, one should use a clear

day. For comparison of pyrgeometers, one should compare nighttime results.

Deviations of more than 6% can be used to correct the calibration factors.
