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.
Measuring Resistance
The Meter offers 2-wire and 4-wire ohms measurement. Press O to toggle between 2-
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.
2-Wire Resistance Measurement
To perform a 2-wire resistance measurement:
1. Connect test leads between the Meter and the circuit under test as shown in
Figure 3-5.
2. If required, press O to select 2-wire resistance measurement mode. 2*4 Wire is
displayed.
The function and measurement are displayed.
