My clamp meter is limited up to 600A
My last attemp measure current stops on 1230A / 3V and it was analog current clamp meter.
( if you want to known what the hell I am trying to do - I am trying repair spot-welder and calibrate ranges on front pannel which was damaged)
My new clamp meter will arrive into my location in 6-8weeks.(I hate this waitting)
From this reason I wish to make tempovery current meter from discrete parts (they are available in local DIY store)
I am able measure current with shunt resistor but I never measured so high current as I need now.
Could anyone help with any idea howto measure this current? I dont need high accuracy only to known how much flow over my 10mm (diameter cables to eletrodes TIG/1.6mm Cu-prum is melting very fast)
Howto implement Peak&Hold function ?
