| E.{Mr Elliott - Chief Engineer} From Ha/Wst. c. to By.{R.W. Bailey - Chief Engineer} Ha/Wst.1/MA.3.9.34. AMMETER FOR R.R. & BENTLEY CHASSIS. We have now arrived at the stage when our ammeter range should be increased from 20 to 30 amperes and we propose to obtain one or two ammeters for experimental test with such a range, i.e. central zero 30 amperes full scale discharge and 30 amperes full scale charge. We think such a procedure will help to protect the ammeter andwe shall not then have to be so particular about accessory current passing through the ammeter or not. Ha/Wst. | ||
