Minimum/Maximum values

When any one-second real-time reading reaches its highest or lowest value, the meter saves the minimum and maximum values in its nonvolatile memory.

From the meter display, you can:

View all minimum/maximum values since the last reset and the reset date and time
Reset minimum/maximum values

All running minimum/maximum values are arithmetic minimum and maximum values. For example, the minimum phase A-N voltage is the lowest value in the range from 0 to 1 MV that has occurred since last reset of the minimum/maximum values.

The meter provides time stamping for 6 minimum/maximum values.

The following table lists the minimum and maximum values stored in the meter:

Characteristics	Description
