Aplab Autocompute LCR-Q Meter – Model 4910

Aplab Model 4910 is a microprocessor based digital Autocompute LCR-Q Meter that meets today’s laboratory requirements, in the production line and the quality assurance area. It features fully autoranging and automatic operation over a wide range of measurements.

Model 4910 measures inductance, capacitance, resistance and quality factor to a basic accuracy of ±0.25% of the reading for values upto 2000H, 2000μF, 2M ohm and Q factor upto 99 respectively. Measurements can be made at a frequency of 100Hz or 1KHz as required and either the series equivalent or parallel equivalent component values can be displayed. Range selection is fully automatic and the LCR-Q meter automatically discriminates between inductors and capacitors. An internal DC bias voltage of 2 volts can be selected for use when testing electrolytic capacitors.

The operating system of the LCR-Q meter provides assistance to the user in selecting the measurement mode and frequency to give best accuracy. If a wrong selection is done, then the corresponding LED flashes prompting the user to change to the proper setting. Loss of basic accuracy due to poor quality of component and operation beyond the operating range of the instrument is also indicated by flashing the measurement units LEDs. Measurements upto 9999H, 9999μF and 100M ohm can be made at a degraded accuracy.

Model 4910 incorporates 4 terminal measuring technique which reduces errors due to electro-magnetic coupling of leads as well as reducing residual inductance and stray capacitance. The integral test jig accepts most common diameters of component leads. Radial and axial components can be directly plugged into the jaws.

The insertion of components with particularly flexible leads will be aided by the operation of the release buttons situated directly below the insert jaws. The unit comes with remote cord to simplify testing of small/large size components
