2、ngs. It is a lightweight and compact unit incorporating advanced design, features and capabilities. Many battery customers are requesting baseline data in order to perform long term evaluation of their battery installations. Having baseline readings can enhance battery manufacturers rapport with the

3、ir customers for enhanced customer service. The data derived can also be used as a quick QA/QC check for process control of individual cells. Impedance is the measurement of electrical path components in a battery whether lead-acid or nickel- cadmium. A capacitively coupled AC current is applied to

4、the cell via two of the four points of the dual point probes. The other two points are used to take the measurements. Therefore, a true four-wire measurement is taken. The resultant effect is measured as impedance using the following electrical equation: E = I * Z whereE is the measured cell ac volt

5、age drop, I is the applied ac current, and Z is the calculated impedance, which has two (vector) components: resistance, R, and capacitive reactance, Xc. The vectors comprising impedance: But the MBITE does this automatically so there is no need for complex mathematics to derive impedance data. (Ple

6、ase note that impedance should be higher in value than resistance.) Furthermore, the test data can be verified by the operator and then stored by pressing the data send button on the probe. The operator is able to view the data via the 5 in. (12 _-cm) LCD. This easily enables the operator to find ou

7、t-of-range cells for further analysis and evaluation. The impedance data measured by the MBITE is identical to the impedance data measured by other Biddle BITE“ products operating. Other features of the MBITE are: Configurable for cell-only measurements, as well as cell/strap and strap-only modes. S

8、imultaneously takes impedance and cell voltage readings. Takes cell readings in less than 5 seconds. Integrated bar code wand for complete traceability to lot number and individual cell. Standard code 3 of 9 bar coding. Does not discharge the cell compared with other techniques. Numerous accessories

It displays and prints cell impedance and voltage data as well as the time stamp of the measurement. The MBITE calculates the (lot) average

10、impedance, the minimum and the maximum of the data set.
