When the damping of an instrument is adjusted to enable the pointer to rise quickly to its deflected position without overshooting in that case the instrument is said to be?

Right Answer is:
Dead beat
SOLUTION
- If the instrument is under-damped, the moving system oscillates a lot before it dismally settles down to its steady value.
- ln case of critically damped instruments, the pointer reaches its final steady position rapidly and smoothly. Such an instrument is also called dead-beat instrument.
- An over-damped instrument produces damping torque more than the required value, as such the pointer moves slowly to its final steady-state value.
