What is Min/Max/Avg recording mode and how we use it in Fluke 77 IV series Digital multimeter?
The main function of the Min/Max/Avg recording mode is to capture the minimum and maximum input values and calculates a running average of all readings. When a new high or low value is detected, the meter starts beeps.
Following steps you have to follow to use Min/Max/AVG recording mode:
- Ensures that the meter is in the desired measurement function and range (Auto-ranging is disabled in the MIN/MAX/AVG mode).
- To activate MIN/MAX/AVG mode, press MIN/MAX labelled button. After pressing the highest reading starts displaying on the screen.
- Again Press MIN/MAX labelled button to step through the low, average and present readings.
- To pause MIN/MAX/AVG recording without erasing stored values, Press HOLD labelled button.
- Again press the HOLD labelled button to resume MIN/MAX/AVG recording.
- To exit and erase stored readings, press MIN/MAX for 1 second or turn the rotary switch.
