| Ha/Wst.1/AD.14.12.31 contd. -2- on these test results and also we should be interested to have from you a statement as to what is the maximum momentary discharge which can be sent through these instruments without their accuracy being affected. We should prefer this figure to be not less than 60 amperes. Yours faithfully, FOR ROLLS-ROYCE LIMITED. | ||
