Description

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 *-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 *0 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.
