This Measuring Testing Instrument, backed by the Mikrosize supplier, features a user-friendly Windows Chinese window interface that allows for intuitive setting of test conditions. Users can easily store critical test data, including test parameters, load curves, and detailed inspection reports, and it supports seamless conversion to Excel format for convenient data analysis and documentation. Such functionality makes it a versatile tool for quality control and R&D departments in industries relying on key and switch performance.

Core Testing Capabilities

Developed with the expertise of the Mikrosize supplier, this Measuring Testing Instrument excels in multiple testing scenarios:

It performs 2D curve testing of gravity and displacement for silicone keys (such as those used in keyboards), metal keys, and light touch switch keys, capturing precise force-displacement relationships to evaluate mechanical behavior.

During conductive button testing, it can accurately measure the dynamic resistance of contacts during the "OFF→ON" and "ON→OFF" transitions, ensuring the electrical performance of conductive keys meets industry standards.

It enables comprehensive parameter detection for PS2 port keyboards and USB port keyboards, focusing on the conduction status and resistance parameters of each key contact to verify keyboard functionality.

High-Performance Configuration

To guarantee reliability and accuracy, this Measuring Testing Instrument (supplied by Mikrosize supplier) is equipped with top-tier components:

It adopts a Japanese Panasonic servomotor and a high-sensitivity load sensor, ensuring stable and precise operation. The test speed range is adjustable from 0 to 100mm/min, with a stroke display accuracy of up to 0.01mm—ideal for capturing subtle changes in mechanical performance.

The load unit supports flexible switching between N, Ib, gf, and kgf, accommodating different measurement standards and user preferences.

Key Product Features

As a leading Measuring Testing Instrument from the Mikrosize supplier, it boasts a range of user-centric features:

Critical parameters such as Peak Force, Return Force, Distance, and Click Rate are directly displayed on the test chart, eliminating the need for manual calculation and reducing human error.

Test curves are stored in the computer, allowing for on-demand enlargement to analyze local details. Additionally, users can arbitrarily specify the number of curves to be placed on a single A4 paper, facilitating side-by-side comparison of multiple test results.

For quality control purposes, users can input upper and lower limit specification values for each test item; the instrument then automatically determines whether the measurement result is OK or NG, streamlining the inspection process.

It supports setting the maximum measuring stroke and stores load-stroke curves and inspection reports digitally—no need for traditional square paper, as reports can be printed on standard A4 paper.

Test data is securely stored on the hard drive, with no limit on the number of stored data sets, enabling long-term data retention and traceability.

Test conditions (including test course, speed, number of test cycles, air pressure, and pause time) are set via the computer in a written format, ensuring consistency and repeatability of test procedures.

The header of inspection reports can be modified at any time, supporting both Chinese and English, to adapt to different regional and corporate documentation requirements.

Inspection reports are generated automatically, requiring no additional manual input, which saves time and improves work efficiency.

Reports can be converted to popular document formats such as Excel, making it easy to share data with team members or integrate into larger quality management systems.
