Frequency Ranging
Frequency measurements are automatically ranged so that a frequency measurement is
always displayed with maximum resolution.
To select a range manually, press F to select the frequency function, and then press
U or V to select a range manually. Manual ranging can be performed on readings
displayed in the primary display only.
If you manually select a frequency range and the measurement exceeds the full-scale
value of that range, 0L is displayed to indicate an overload. Refer to the “Electrical
Specifications” section in Chapter 1 for frequency ranges and full-scale values.

wire and 4-wire measurement modes. The Meter displays 2*4 Wire at 2 wire or 2x4 wire
resistance measurement and displays 4 Wire at 4 wire resistance measurement.
