During cooling down of the cryocooler, until it stabilizes at a low temperature, the electric current value is
about 10% larger than the stationary electric current.
Longer flexile hoses also increase the electric current. (A set of 20m flexible hose will increase the electric
current by 5% compared to the nominal value.
