DCM300 and DCM320 Digital Clamp Multimeters
The DCM300 and DCM320 Digital Clamp Multimeters measure AC current,
AC voltage, and resistance/continuity. The meters use a current transformer to
measure current without opening the circuit.
The meters automatically select the correct measurement range and have a 4000
count resolution. (The maximum reading is 3999.)
The DCM320 meter provides true RMS readings for both AC volts and AC
current.
