This instrument integrates the strong function, excellent performance and simple operation. It either suits the needs of high-speed measurement on production site or meets the requirements of precision test for quality inspection, metrology and lab.
Model LDG2817D LCR Meter is a test instrument with high price-performance ratio, newly researched and manufactured by our company. It is used automatically for testing component parameters including inductance (L), capacitance (C), resistance value (R), complex impedance (Z), phase angle (θ), quality factor (Q) and dissipation angular tangent value (D). The instrument integrates the strong function, excellent performance and simple operation. It either suits the needs of high-speed measurement on production site or meets the requirements of precision test for quality inspection, metrology and lab.
Comparing with the former general component parameter test instrument, Model VT2817D instrument has improved in the following fields.
In order to improve the immediacy and readability, a large-sized LCD display screen is designed for Model VT2817D instrument, displaying the test condition and the measured results. Model VT2817D instrument is also equipped with the man-machine interface convenient for application.
In order to meet the needs on the different sites, the instrument has two sets of sorting process with multi-digit parameter setting and high-resolution. The instrument can be connected to automatic test unit through the sorting interface, thus realizing automation test.
This instrument is equipped with RS-232 interface. It has effectively realized the communication with computer and provides the possibility of remote control and data collection.
This instrument is designed with constant signal source inherent resistance. It ensures that the voltage applied on the same measured part or the current signal does not change as the measurement range is adjusted. For this purpose, it avoids the phenomena that it is difficult for instrument to select the measurement range of the measured part located at the borderline of the measurement range.
This instrument has the key lock function and the status-holding function. It avoids the false operation and meanwhile, the instrument with customization of individual character has the default function when it is started up.
The instrument has the multiple variable measurement conditions. The typical functions are shown as follows:
- Test frequency: Eight selective frequencies: 100Hz, 120Hz, 1kHz, 10kHz,20kHz,40kHz,50kHz,100kHz
- Testing signal electric level: Three selective testing signal electric levels: 0.1V, 0.3V, 1.0V
- Test speed: Fast speed, middle speed and slow speed for selection;
- Clearing zero: The instrument can carry out the zero-clearing by sweep frequency on the ends of measurement in open-circuit and short-circuit. The stray capacity remained at the test end of instrument and lead wire resistance are eliminated so that test precision may be further increased.
The instrument has three data reading modes and two sorting modes.
Direct reading: Directly display the parameters on the measured part;
Absolute error: Read the differential between value and nominal value;
Relative error: Read the percentage error between value and nominal value;
Components sorting: The test instrument provides two sorting modes: Three selectors status (sorting for three selector major parameters and one selector minor parameter); one selector status (sorting for one selector major parameter and one selector minor parameter)
The instrument provides two communication interfaces.
Serial line interface: RS-232 interface provides the convenience for instrument and the communication between the instrument and peripheral serial communication. The instrument transmits data to peripheral equipment. The peripheral equipment shall set up functions and parameters on the instrument through the interfaces. It can be basically substituted for function of key board.
Handler Interface: This interface synchronizes the instrument with the component mechanical treatment equipment and does the test and sorting to the component. The selected results are outputted to mechanical treatment equipment.
