| TEMPERATURE COMPENSATION |
Contrary to some claims, all chronographs have
plastic parts in the product that relate to optics.
Like all plastics, these parts suffer from
the effect of
temperature variations.
These parts are present all over the unit, for example:
Sensor cavities, called skyscreens, are plastic.
Some manufacturers, including us, use plastic housings.
Some use lenses made of plastic.
Even rails to hold skyscreens in some cases are plastic.
Wherever there is plastic part, temperature variation causes considerable expansion and contraction problem. We are not aware of any competing chronograph manufacturer who has solved this problem. Some claim that their units are made of metal, however a closer look will reveal that the most critical parts are actually made of plastic.
We are the first manufacturer to solve this problem with digital control. Our plastic housing, top and bottom, are injection-molded on a single die to provide temperature-expansion tracking. An internal temperature sensor measures the ambient temperature. The computer then calculates correction factor required the instant the shot is detected. Each shot in the string has its own temperature stored with it.
If you are adventurous and dare to switch CE-2 into CF-2 mode, you can view each shot's temperature. You can also do statistics on the temperature.
To further improve our product, we have also incorporated
a digital temperature compensation control for the crystal oscillator used to measures
velocity.
