    I have a requirement for running hours counter - analogue (non-tempered type) by the customer. What does non-tempered type means?

    Tempered or tampered ?


    Tampering means unauthorized resetting of the meter

    Tamper proof would be a meter that cant be altered.

    Perhaps this is what they ask

    The customer means to say "tamper proof", as opposed to digital devices that can be altered without leaving traces.
    The classic hour counters can also be tampered with if taken apart and reassembled, alas not without breaking the seal of the recessed screws.
