Brief Introduction
JK628/JK629/JK629B handheld DC low resistance tester is a high precision and wide range portable handheld instrument controlled by high performance 32-bit ARM microprocessor.
The built-in large capacity lithium battery can measure passive components accurately and conveniently in any situation for a long time.JK628 is equipped with 5.6 "high-definition color LCD display, large font display is more convenient for you to read data.he instrument can measure the resistance of 0.1μΩ～200MΩ with a maximum display number of 20,000.It has a current test mode that can be adapted to different requirements of the test. It is equipped with Mini-USB communication interface for remote control and data acquisition and analysis.
JK628 hand-held low resistance tester can measure various high, medium and low value resistors. JK628 hand-held low resistance tester is widely used in various kinds of switching contact resistance; connector insertion resistance; relay package and contact resistance; transformer, inductor, motor, deflection coil winding resistance; wire resistance; metal riveting resistance of car, ship and aircraft `printed board line and hole resistance'.
Performance characteristics
●0.1uΩ resolution
●Four-wire test rod and four-wire crocodile clamp (to offset the contact resistance on the line), thus providing high-precision measurement;
●The upper and lower limits can be set for comparative measurement to facilitate component sorting and automatically judge whether the measurement object is qualified or not.
●Built-in rechargeable lithium battery, long service life;
●1000 pieces of data can be saved, read and deleted.
●USB Data Transfer (Installation-Free Driver) and Bidirectional Data Exchange with PC
●Data retention function, keep measurement results, read at any time
●LCD backlight function, can also effectively read in dark environment
●ZERO Zero Clearing Function, Relative Value Measurement Mode
●IND Inductive Resistance Measurement Mode
