I have been using accuraspray for measuring inflight particle temperature as well as velocity. But I was facing some problem like when I decreased the arc current, the accuraspray was showing more than 10,000 C temp. And when the arc current was being increased (upto 700A), the accuraspray was showing more relevant value (3800C). Also the size of plasma plume got reduced at the time of 700 A.
