Digital Gram Scales Sydney My Digital Scales Read "E" Everytime I Turn Them On?

My digital scales read "E" everytime i turn them on? - digital gram scales sydney

I have a few digital scales Ohaus CS200. Weighing 200 grams and up to a week ago, which worked perfectly, but now every time you activate it with "E", which probably means the error? How do I solve this problem?
