RJ3545Precision DC Resistance Tester
RJ3545 High precision DC resistance tester can measure the resistance of motors, transformers and other coils and the contact resistance of relay contacts through the four-terminal method, and measure the DC resistance of fuses, resistors and various conductive materials. The built-in OVC thermoelectric potential compensation function makes the test results more accurate.
The RJ3545 not only meets the high-precision testing requirements of the laboratory, but also has a variety of communication interfaces to meet the requirements of automatic production line mass testing.
Main feature
Wide measuring range 0.01μΩ~1200MΩ, 12 steps, max. 6.5 display digits
Maximum test current 1A
Flexible I/O interface, compatible with various test systems
OVC thermoelectric potential compensation function, effectively eliminate the effect of thermoelectric potential
Low current mode test prevents the object under test from fusing, heating or magnetizing
Multi-channel scanning mode can be set, external RJ35-SXX multi-channel scanning unit (optional), to realize multi-channel test
