The needle zeroes correctly and I have tested it for accurate reading at 100uA using a 10V source and a 100K resistor. The coil resistance is 324 Ohms. There is a tiny crack on one edge of the transparency. The actual item is shown. The width is 72mm and the height is 53mm. The panel circular cut-out required is 53mm diameter.\u003cbr\u003e\u003cbr\u003eYou could use a 9V battery and normal skin resistance to move the needle, and it will certainly read the current generated by potato batteries, very small solar cells, photodiodes and phototransistors etc.","brand":"HJW Electronics","offers":[{"title":"Default Title","offer_id":58501264015744,"sku":null,"price":14.9,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1007\/2136\/1280\/files\/il_fullxfull.6090197150_g3d4.avif?v=1784582146","url":"https:\/\/shop.usefulcomponents.com\/products\/100ua-microamp-moving-coil-meter-with-10a-scale-72mm-width-0-1ma","provider":"HJW Electronics","version":"1.0","type":"link"}
