40000 Count handheld LCR meters measures inductance, capacitance, and resistance quickly and precisely. The meters also includes handy functions such as data hold, Minimum/Maximum/Average recording, tolerance sorting, and relative mode. Measurement data can continuously transfer to a PC via the meter's mini USB interface, using either the provided data logging software or SCPI commands sent from a custom program. Fast auto range design for rapid, easy component measurements. USB (Virtual COM) interface. Software for datalogging and front panel emulation available as free download. Selectable auto-power-off options. Applications: Passive component trouble shooting. Electronic assembly. Quality control (component sorting). Measurement parameters: L/C/R/Z/D/Q/Theta/ESR.
