| Continuation No.3. rate the Pointer would reach the Red line on Blue portion of scale before the Battery is actually fully charged. We can supply both these Instruments compensated for variation of charge rate. They can be corrected for variation of 50% above normal charge. We enclose Blue Print showing how this particular type should be connected in the charge circuit and you will observe that both the Battery Voltage as well as the charge current passes through the Instrument. | ||
