how to check maximum current drawn in a month in PM 8000 pmu meter ??

Hello @hariqatar80 ,

The answer depends if you are trying to setup the meter to collect this information or if you have a meter already in the field and you are trying to determine this information from the collected data.

If new setup, you can use a maximum module, data recorder and feedback module. The maximum module would be linked to the measurement desired, a maximum module can only have 1 input so if you need for each phase you will need 3 maximum modules. The data recorder would have the maximum module's output as a source and the clock module's new month pulse as the record input. Link the record complete pulse output from data recorder to input of the feedback module. The output of the feedback module would link to reset input of the maximum module.
At the start of each month, the data recorder would record the maximum value for the month, then reset the maximum module. The feedback module is required to prevent logical looping inside the meter between data recorder and maximum module.

If you already have a meter in the field and has a moth of data collected, you can look at the HIST log log in ION setup to see the last 35ish days. This logs the maximum current every 15 minutes. You can take the maximum of the individual intervals to get the maximum for the 35 days. 

If you are using software like PME to collect the logs you could look into the database to go back further is time than last 35 days.
