Your DMM ,if like 99.44% of the others, ONLY samples every 3 reading per second, so you should adjust your DC amps function to be similar.
Also, instead of taking 100 samples, take 64 or 128. Makes ... |

It's worth understanding that the ADC's used on 99% of low priced DMM's
are what are knows as "dual slope integrating ADC's". These are one of the
few ADC's giving high accuracy at low pr ... |

Ok. I have applied the Olympic Averaging in simulator only for DC Current and other sensors are working. In the morning I will do it in hardware |

As I am using four ADCs, can I apply the Olympic Averaging only to the dc_current measurements. Can others still work the way they are? |

Hello honorable members and admins!
I am sensing AC and DC current and voltage and frequency. Everything is working but the Dc_current swings a lot. AC Voltage, AC Current, Frequency and DC Voltage a ... |

There are a couple of tweaks/comments.
First on the PIC, you should not use ADC_CLOCK_INTERNAL above 1MHz
CPU clock. Doing so results in poor ADC accuracy. You should instead be
using the master os ... |

I'm glad it works. I suggested division by 8 because it is slightly faster. But the biggest difference is defining avgResult as unsigned int 16. That way you always manipulate only two bytes instead o ... |

Some three posts back there is a complete code. That compiles without any problem.
@PrinceNai, the code is working now! So much thanks! I am so much happy for this!
Now, I have to study the cod ... |
