Chroma 11210

Chroma 11210 Battery Cell Insulation Tester  The Chroma 11210 battery cell insulation tester is an instrument used for accurately measuring leakage cur (LC) and insulation resistance (IR) of battery jelly-roll/dry-cell as well as various insulation materials. In addition to standard LC/IR measurement, it has a unique function that detects partial discharge (PD) or flashover that may have occurred inside the insulation material during the high voltage insulation testing process. Due to special circuitry used in the Chroma 11210, no extra time is required for the PD detection function. Both LC/IR measurements and PD detection tests can be performed simultaneously and both test results will be reported automatically.With an ample charging cur capability, the Chroma 11210 can easily achieve high speed testing with automatic execution of the test sequence. This sequence can be automatically executed in 20ms or less for a single DUT (Device Under Test); meaning tests performed in the production line can achieve process rates of 50 pcs/sec or more. The contact check function in the Chroma 11210 employs advanced technology to instantly detect those which do not make secure contacts during the tests. It takes only 5ms to do a thorough contact check before and/or after the measurement. Specifications for the Chroma 11210 Battery Cell Insulation Tester Include:
