LCR Meter – 104A

Model AB-104A is a Micro –Controller based precision LCR meter. With basic accuracy of 0.1 %.it offers various test frequencies ,can display two selected parameters simultaneously, has internal Bias for electrolytic capacitors. Auto mode gives auto ranging & automatic component identification. Four wire measurement minimizes error in reading. RS232 Communication & Binning facility upto 8 bins possible. Loading of pre-setted parameters also possible to save time.

Reading can be Hold for documentation. SER & PAR modes are available.

Instruments are calibrated with our calibration & service facility center with standards having traceability to National standards.

Optional accessories are Kelvin clip, SMD tweezer,capacitor insertion jig.
