Product Details

Introduction

GKT2818A/B precision LCZ tester is an impedance measuring instrument with high precision, high stability, fast test speed, wide test range and large data storage space. It uses an advanced 32-bit microprocessor and a 4.3-inch color display. , Humanized interface menu design, convenient and quick operation, can perform routine, comparison, sorting, scanning measurement, can save or read test data and related content in large capacity, provide a basis for users to control product quality and analyze product characteristics, and It greatly meets the different testing needs of users; at the same time, the instrument also provides Handler interface and RS-232C serial communication interface, which provides conditions for automatic measurement, remote control, and data transmission.

Performance characteristics

■ 4.3 inch color screen display,

■ Test frequency: 50Hz to 200KHz, arbitrarily set (only 2818A)

■ Test frequency: 50Hz to 200KHz, 37 fixed frequency points can be selected (2818B)

■ Test level 10mV ~ 2V, 10mV stepping (when the internal resistance is 10Ω, the highest setting voltage is 1V)

■ Basic accuracy 0.05%

■ High-speed and high-efficiency measurement: the fastest 32 times per second

■ Load correction: According to the specific sample and parameter instrument to calculate and correct, get the required test data.

■Comparator function: After setting one or more sets of range values of the product measurement parameters, the instrument can compare the obtained measurement value with the set value and judge whether it is a qualified product or a defective product.

■ Real-time recording of measurement results, with measurement date, product measurement data file name, statistics on the number of measurements in a day and other related information, the data will not be lost when the machine is turned on and off

■ File management function: 100 sets of product test data can be stored

■ Sorting function: to subdivide the product level, cooperate with the control mechanical sorting system to sort and classify the products.

■ V, I test signal level monitoring function

■ Up to 8 points of frequency or 8 points of voltage can be scanned and measured, and the measurement results can be displayed at the same time

■ Communication interface: RS232C/HANDLER
