BATTERY INSULATION TESTER BT5525

Detect contamination that could cause defects. Improve battery cell productivity through high-speed testing.

Detecting minuscule insulation defects caused by contamination (Break Down Detect function)

The BDD function is a proprietary testing function that can detect minuscule internal short-circuits caused by contamination (with metallic matter) at the stage before battery cells are filled with electrolyte. By identifying and eliminating defective parts at an early stage in the production process, the BDD function helps prevent the risk of hazards such as fires and accidents caused by heating after battery shipment. In addition, minuscule internal short-circuits in cells accelerate battery degradation. The BDD function will contribute to the production of batteries with greater durability and electrical performance.

Preventing testing do-overs due to erroneous judgments

The BT5525 provides a contact check function to determine whether the instrument has made proper contact with the circuit under test by measuring the capacitance between the measurement terminals (stray capacitance and the capacitance of the circuit under test).

Stable insulation resistance testing, even in noisy environments

Hioki succeeded in significantly reducing the effects of external noise by drawing on insulation resistance tester measurement technology and design expertise cultivated over many years.
As a result, the BT5525 can perform stable, variation-free insulation resistance testing at a level of quality that lets its detect internal short-circuits caused by contamination.

*1: Constraints involving the output generator will result in an error, making measurement impossible, if a capacitive load of approximately 50 μF or greater is connected while using a current limit setting of 5.1 mA or greater.
*2: When using a current limit setting of 5.1 mA or greater, measurement will be forcibly stopped if the output voltage is not at least 20 V at 200 ms after the start of measurement. Measurement will be possible 1 s after forcibly stopped.
*3: If the set current limit value is from 5.1 mA to 50.0 mA, the current will be limited to 5 mA after the output voltage reaches the set voltage.
