    keyword=target temperature

    When we asked MCC to increase the current from 35uA to 70uA, the target temperature jumped above the hihi limit and could not automatically come back
    to normal level. So we had to ask MCC to lower the current to 50uA and the temperature dropped below the hihi level but stayed at hi level. It seems the PID
    is not working very well. Is it because somebody adjusted the PID parameters?
