Viewing and capturing real time values of Electronic balance measuring instrument on television set and computer monitor larger screens
Three possibilities come to mind:
(1) Purchase a scale with a digital output e.g, https://www.arlynscales.com/digital-indicator/industrial-scales-with-analog-and-digital-outputs/ , send it to your computer, and output it to a monitor (depending on the scale's output format, it may be possible to send it directly from the scale to a monitor)
(2) Point a USB webcam towards the scale's digital readout, plug that into to your computer, and then display on a monitor.
(3) Same as no. 2, but use a digital camcorder that has a digital output that can be displayed directly on a monitor, without the need for a computer.
