    Doest not work on line

    We have purchased one no. BAT 500 model. Impedance value measured on batteries off line, it working well. Where as it is not working on-line. In the technical catalog it is clearly mentioned as battery impedance can be measured without shutting off the battery, where as at site it is not happening. We have taken this issue with service department, after long wait they have given one more meter as replacement. The replaced meter is also behaving in the same way as the earlier one. Hence this meter is not worth for buying as it is not meeting the ground situation.

    ✘ No, I do not recommend this product
