  • With Kelvin four-wire Connection
  • Product description: JYL600A/300A contact resistance tester can measure contact resistance of high-voltage switch and circuit breaker, also can test primar side resistance of transformer and grounding wire in groups.
  • INQUIRY

JYL600A/300A adopts the Kelvin four-wire measurement method, which effectively eliminates the influence of the resistance of the test line itself on the test results, this instrument can test contact resistance of high voltage switch and circuit breaker, also can test primary side resistance of transformer and  grounding wire in groups.





FUNCTION INTRODUCTION

With big test current can reach 600A.

The test output current is from high accuracy switch type constant-current source, no manual adjustment required, which will shorten test time by 3 seconds and improve test accuracy.

With four-pole wiring method to eliminate the effect of test wire resistance on test results effectively.

With overheat protective circuit which can ensure the instrument is reliable and stable during long time continuous work.

The instrument is simple in operation. With a light weight, it is suitable for outdoor work.

With U disk storage interface that can export data to form test sheet.

Can store 99 sets of data. the data will not be loosen as power failure and convenient for looking up.

With RS485 communication interface for remote control measurement(with operation software) .

With built-in thermal printer and permanent calendar.
