SRamakrishnan youcan try using. make sure the comparator IC do not burn out.0-26 would be fine not 26-0-26 (dont use)

SRamakrishnan the input diode connected at NR connected in reverse. if you are connecting battery at output, there is risk of diode blast. make sure you set input source higher voltage and then connect output load/battery with diode.

سؤال: DC current measures are not accurate. where AC current is good. does anyone face the issue

السؤال بواسطة SRamakrishnan على 2024-07-05 01:33:50

mauro070463 perché bisogna rilevare la continua con un campo magnetico variabile e amplificare il segnale, quindi in circuito abbastanza sofisticato e non preciso a bassi prezzi, per misure accurate il cavo deve essere nel mezzo della pinza, in più la distanza (il diametro della pinza) influisce sulla precisione e sensibilità.
