Min/Max/Avg Measurements

Min/Max/Avg mode captures the minimum, maximum, and average readings of a given output
signal over an extended time. The Clamp beeps when it senses a new high value or new low
value. It applies for both reading except for Inrush Current/Peak Current. Push
reading update (recording continues).
This function works in current, voltage, and frequency modes:
1. Push M to enter the Min/Max/Avg mode.
The maximum reading shows on the display.
2. Continue to push M to select between the maximum, minimum, average, and live readings.
The cycle continues each time you push M.
3. To exit Min/Max/Avg mode, push and hold M for >2 s.
The Min/Max/Avg function does not support Auto Hold and Inrush Current/Peak Current.
Auto Power Off is always disabled when you use the Min/Max/Avg, Auto Hold, and
Logging functions or Fluke Connect is active.
