DS-e/d Series Armature Tester

DS820e DS820d
.
Scope
Applicable to accurate test of armatures made by single-fork, double-fork or large and small bar winding process; and test of armatures made by piezoresistor, carbon commutator, equalizer, double-insulation and other special process
Functional Features
● All electrical performance test items of an armature, including insulation resistance, AC HIPOT, bar-to-bar resistance and transresistance, winding hook direction, welding resistance, turn-to-turn surge test, are completed automatically at one time;
● Measure the welding resistance accurately to the micro-ohm level; the automatic judgment threshold for armature welding resistance can be set to 100 micro-ohms (ie 0.100 milliohms) or even smaller; discover armature rosin joints and nonconforming welds fast and accurately; the screen provides fault location information to facilitate armature troubleshooting
● Unique automatic range switching and test tracking; therefore a higher accuracy than other similar instruments throughout the measurement range. It is not required to set the instrument measurement range as the armature resistance range is not required to know beforehand; even an ordinary operator can sample an armature with its parameters unknown very easily and formulate the automatic judgment criteria
● Proprietary bar-to-bar resistance fuzzy sort and identification; automatically identify single-fork, double-fork or large and small bar winding process, and hookup direction; automatically track and test an armature regardless of where it is placed;
● Automatic judgment of turn-to-turn surge test between any bars under any form of surge; more accurate identification of turn-to-turn faults in a large number of armatures with significant difference in process
● HIPOT, turn to turn surge test voltage settable, automatically generated and regulated; test data immune to fluctuations from external grid; offset the inherent leakage current of test system automatically
● Enable or disable any test items, set pass criteria; release automatic light or sound alarm upon test result over-limit
● Excellent dustproof, cooling, double-station lighting design
