1) Transition zone is dielectric dependent: dK = dielectric permittivity. Unit will function but accuracy will decrease in Transition Zone.
2) Refer to Ambient Temperature vs Process Temperature graphs in instruction manual.
3) Bridging is defined as continuous accumulation of material between the probe elements.
