Function: Unknown
Technical: PORTABLE INSTRUMENTS IN CONSTRUCTED TO BE MOVED FROM PLACE TO PLACE FOR TESTING PURPOSES. THEY ARE USED MORE OR LESS FOR EXACT MEASUREMENTS & THEREFORE ARE DESIGNED FOR GREAT ACCURACY. ANCESTORS OF MOVINGCOIL INSTRUMENT WERE 'SIPHON RECORDER' DEV'D BY WILLIAM THOMSON (1867) FOR TELEGRAPH INDUSTRY & AND 'FISHBONE GALVANOMETER' INVENTED BY MARCEL DEPREZ (1880). JACQUES D'ARSONVAL SUGGESTED FIXING THE 'FISHBONE' IN DEPREZ'S INSTRUMENT, & MAKINGS ITS COIL MOVEABLE. MAIN DISADVANTAGE OF THE D'ARSONVAL VOLTMETER WAS THAT TO WORK PROPERLY, IT REQUIRED A VERY LIGHT MOUNTED COIL SO AS TO BE READILY MOVABLE. AS SUCH, IT DIDN'T MEET CRITICAL SUCCESS TIL TOWARDS THE END OF 19TH CENTURY.
