The limit compare mode provides pass/fail indicators to quickly show if a test passes or fails to help eliminate mistakes, especially for results that are close to the limit.

5.5 digit resolution Measure volts, ohms and amps with a basic V dc accuracy of 0.015%. Frequency measurements Save cost and bench space by replacing a multifunction DMM and counter with one instrument.

DC leakage current measurements Make sensitive low current measurements with 1 nA resolution. Dual display Measure two different parameters of the same signal from one test connection. PC Connectivity Easily connect to a personal computer using RS-232 or USB.
