This is a Keithley DMM7510 Digital Multimeter.  This unit is in GREAT condition, and guaranteed fully operational.  I have several of these, one per bid.  Each unit comes with a test lead set and quick-start manual as shown. 

The DMM7510 7.5 digit multimeter combines a precision, high-resolution digital multimeter (DMM), graphical touchscreen display, and high-speed, high-resolution digitizer to create the first graphical sampling multimeter. With pA-level sensitivity and 1Msample/s sampling, it accurately measures ultra-low sleep mode currents and transmit drain currents from wireless devices.

Best Accuracy (one year):
DC Volts: 0.0014%
DC Current: .0060%
Resistance: 0.0024%
Digitizing Rate:
1,000,000 readings/s

Display:
Touchscreen Display

High sensitivity enables the DMM7510 to measure very low levels of voltage, current, and resistance, and detect small changes and signal drift.

Highlights

  • DC voltage sensitivity: 10 nV
  • Current sensitivity: 1 pA
  • Resistance sensitivity: 0.1 µΩ
