| Exel. Report. -2- EFC2/Tl.2.26. It perhaps should be mentioned that these are not the first ammeters we have had from Messrs. Elliott. We have previously had an instrument which, although it did 10,000 miles reasonably satisfactorily, developed a fault which negatived the 10,000 mile test. It will be agreed therefore that for this reason it is desirable to have two positive 10,000 mile tests. The appearance of the instruments is practically identical with that of the Weston, with the exception, of course, of the name. EFC. JC.3 attached. | ||
