| Y4118 To Hm{Capt. W. Hallam - Head Repairs}/Mr. Chandler. From EFC. EFC1/T16.2.26. RE WESTON AMMETER NO. 282467. - EX CHASSIS GPK.14 - We have tested this ammeter and can find no fault. Herewith is the wording of my assistant's report. "This ammeter seems to be quite O.K. There is not the slightest sign of sluggishness or sticking. The same reading can be obtained with the same load any number of times on any part of the scale, on both 'charge' and 'discharge' sides. The needle oscillates quite freely and is very sensitive to small variations of current. It reads about 1.5% high at 20 amperes on both sides of the scale." Herewith we return the instrument to you.
