Select between Auto or
Manual ranging
The 2712 is a full featured auto ranging true RMS DMM that combines
performance, value and functionality. The 40000 count LCD has a green back
light that allows the meter to be used in dimly lit environments. The 2712 can
measure resistance values up to 40 Mohm and capacitance to 40 uF 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.
