Uses:
Used to measure the transformer, motors, transformers and other inductive device DC resistance, it can quickly make the test current reach a steady value to shorten the measurement time significantly.
Features:
Advanced large-scale integrated conversion circuits make high measurement high sensitivity, digital display and visual clarity. High automation of equipment: Automatic digital-zero, automatically discharge on DUT (Device under Test) , it has the automatic protection function because of misuse of a variety of human mistakes.
