DC multi-resistor tester

The THT-DZY-A DC multi-resistor tester can test transformers, motors, switches, relays, connectors and other types of resistors with the measuring range of 1 uΩ~2MΩ. The instrument produces high-precision constant current flowing through the DUT (device under test) for 4-terminal measurement, able to effectively eliminate the lead errors and applicable to users’ high-precision measurements. The DC test is adopted and it can fast scan and test up to 10 groups of loads, so it is particularly suitable for measuring the copper resistance various types of transformers and inductors; this instrument has extended the functions of similar instruments, and users can directly set the two groups of nominal values, namely, direct-reading display upper/lower limit of the resistance, nominal values by the percentage and percentage error values. Moreover, all set judgments target the full scale, which has greatly improved the application scope of the instrument; in addition, the change of test speed (fast, slow), the whole-state and full set value power-off protection, as well as other functions also greatly facilitate users’ application of the product.
