The Outline
Model AX-222, Digital LCR meter, can easily measure not only electronic part such as coil, electrostatic condenser, and resistor but also contact resistance like switch, relay and internal resistance of a battery and junction capacitance of semiconductor, and every elements.
Built-in comparator, it can be informed a judgment result by LED indication and buzzer also be printed out.
With a function of auto range and auto mode, it can measure to select the most approximate range automatically for measurement thing of an unknown value.
It is selectable a range by hand, will become shorten the measuring time by range switching.
Display shows a value of LCR for 3½ digits, at the same time indicates a value of D (loss factor) 3½ digit when L or C measurement.
Analog voltage outputs proportional to the measurement value, it can be connected to analog recorder or analog comparator, and others.
