      Are any of the question asked already going to be answered? or am I just wasting my time even looking? Should I just find a Fluke dealer?

          what feature will log the highest amps or volts for bursts such as measuring welding current only while the current is flowing?

          Answer This Question

          When the "MAX/MIN" button is pressed, the meter keeps track of the Maximum and Minimum values and the difference between the Maximum and Minimum values as the meter continues to take samples. 1. When measuring, press "MAX/MIN" button to toggle between the Maximum value (MAX) and the Minimum value (MIN). If a new Maximum or Minimum occurs, the display will update with the new value. 2. Press "MAX/MIN" button for more than one second to return to normal measuring mode. For the full features/instructions please see the Instructions/Assembly document under Additional Resources From the Manufacturer
