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
®
".

Single-handed operation
The ergonomic design allows both left and right handed users to rotate the
knob while holding the meter in one hand. While one hand keeps the probe
on the circuit, the other hand changes the meter’s function. This speeds up
troubleshooting because you don’t have to locate the probe point in the
circuit again.
This convenient feature allows you to
hang your DMM on any magnetic
metallic surface freeing up your
hands for troubleshooting.
