Three channel transformer DC resistance tester

Product Introduction

The instrument can complete a single measurement, three-channel simultaneous measurement, three itemized test volume, automated testing to help magnetic, temperature conversion function, with a data interface, one connection, the testing process down the line without stitches .

1, the instrument automatically selects the output current ( maximum possible output 40A).
2 , wide measuring range (0Ω-50Ω), capable of measuring transformers, transformers and other inductive DC resistance.
3 , 480 * 272 dot matrix display with 65K -color screen, display data legible.
4 , the instrument with a perpetual calendar , 100 sets of data storage , temperature automatic conversion functions, shutdown without data loss . The machine also has a printer can print the test data output , "U disk" interface to facilitate the export data for inspection editing.
5 , the instrument has RS485 communication interface , with PC control software, remote control measurement.
6 , the same measurement instrument has three features to cope with star connection wiring to complete the three-phase windings of a direct resistance measurement, automatic calculation of the three-phase unbalance , greatly saving measurement time and improve efficiency. Test can also be used by the phase function -by- phase test for YN, D (Y) connection of the transformer , the test is completed , automatic calculation of the three-phase unbalance .
The instrument is also equipped with automatic aid magnetic feature, then the five core transformer windings for low- angle test column , using high and low string excitation methods for testing , helping magnetic circuit inside the instrument automatically linked windings can be quickly and accurately test the low voltage winding DC resistance.
7 , the machine has a sound alarm discharge , discharge instructions were clear , to reduce misuse.
8 , the machine has misconnection AC380V power input protection alarm protection, reducing misuse damage to the instrument , the machine also has a perfect arc tensile EMF protection ability .
9 , the machine has a wide application temperature , high precision, shockproof , anti-jamming , high stability, easy to carry and so on.
