Hello George. Thanks for the quick reply! It works perfectly. I can defenitely use this emulator in class. Apparently, most of the students use a more recent model: the 82 Plus. The design is slightly different but I could not see any difference with repsect to the buttons of both models. However, do you, by chance, also have an emulator for the Casio fx-82 PLUS? Thanks in advance! Markus

Effective Clear Width is the width of the opening measured at right angles to the wall in which the door is situated from the outside of the door stop on the closing side, to any obstruction on the hinge side. Therefore, if the door only opens to 90 degrees, then the ironmongery projection must be taken into account, but if the door opens beyond 90 degrees, then the measurement can be taken from the door stop to the door leaf, as shown below.

When used near solar noon over multiple clear, unpolluted days during spring and summer months, accuracy of the Clear Sky Calculator is estimated to be ± 4 % in all climates and locations around the world. As an example, modeled incoming shortwave radiation (SWi) from the Clear Sky Calculator closely tracked measured SWi (data from a heated and ventilated Kipp & Zonen CM21 pyranometer) for a clear day (April 21, 2012) in Logan, Utah (Figure 1). The ratio of measured SWi to modeled SWi was between 1.00 and 1.05 (0 % and 5 %) from 9 A.M. to 6 P.M. (solar zenith angles less than 65°) (Figure 2). The average ratio from two hours before solar noon to two hours after solar noon was 1.02 ± 0.01 (2 ± 1 %). A more detailed discussion of Clear Sky Calculator accuracy is given here, where the necessary accuracy of the required inputs is discussed. (Source: www.apogeeinstruments.com)
