The Elmo CL (Xenon) I am borrowing is running around 28 fps. I've seen posts and the Elmo manual explaining that an incorrect running speed can be changed by moving the belt to the different set of pulleys, changing between 50 & 60 Hz. However this model I'm working with only has one set of pulleys. Maybe this is a newer model? On the serial number plate it does say both 50 & 60Hz.
There is room on the teethed pulleys for the belt to move to the left but I swear it is the same tension. No significant difference. Not sure what else to do. Appreciate any suggestions. -alee
