| V4622 To Wd.{Mr Wood/Mr Whitehead} from EFC. c. ROY.{Sir Henry Royce} EFC1/T12.9.25. X.4622. ELLIOTT AMMETERS. With reference to the four Elliott ammeters recently received for test, two of these are slightly faulty; in one it is not possible to adjust the zero correctly; in the other there is a slight crack starting from the zero adjusting screw which crack would probably develop. We had a similar fault with the previous single sample ammeter which we had from Messrs. Elliott. I think the two ammeters should be returned to them for correction. (Nos. 140998 & 141000) The two of the four received which are O.K. are being put on two experimental cars. EFC. | ||
