| Roy.{Sir Henry Royce} From Ha/Wst. Ha/Wst.2/MA.5.4.34. FERRANTI AMMETER FOR R.R. CHASSIS. We have just received back the sample Ferranti ammeter which was returned recently to the makers due to the case not being insulated. The instrument has now been retested and we find that there is still an earth between the terminals and the case. We think it a good plan if you will invite the Ferranti Representative to visit us so that the instrument can be examined in his presence to discover the cause of the failure. Ha/Wst. | ||
