    It indicates the maximum demand of a particular consumer over a period of time. It is used in calculating the electricity bill under KVA maximum demand tariff category.

    Can you do a one ms or even one us delay? If so, then just use a counter. You can have as long of a delay as you want.

    Explain properly otherwise no body could help you.Which input you are talking about?
    Do you want to measure current or voltage using 8051's ADC module like a digital multimeter?

    Next time you post please be a bit more clear.

    Good luck

    Do you have an output from your DVM? I haven't seen too many like that except for the very expensive type used in a lab.

    Actually, I want to program the 8051 to work as the maximum demand indicator. By this, I want to measure my college maximum demand. For this, I take the input from my college panel board and I will check it from previous values at regular intervals of time. I considered as this interval as an hour. Now, anyone suggest me how can I interface the 8051 with my college panel board. If my panel board consists of analog meters.
