T^{RUE RMS}
Auto/ Manual Ranging
Select between Auto or
Manual ranging
The 2708B is a full-featured auto ranging true RMS DMM that combines
performance, value and functionality. The 3400 count LCD has a 34 segment bar
graph that simulates analog responsiveness. The 2708B can measure resistance
values up to 34 MΩ. With the auto power-off-feature you won’t have to worry
about accidental battery consumption. Value-packed features make this meter a
must in every "Tool Kit^®".
