Re: Ac measurement up to 400 vac

Thanks sir for your advise, I used a transformer and I was able to read Ac up to 300 vac and the circuit was very accurate same reading with my Unit digital meter now am ready to make my voltage stabilizer it will have a low and high cut option and display both input voltage and output voltage on lc...

Re: Ac measurement up to 400 vac

But i have an ac voltage stabilizer here with me that has worked for months very well but is using that second setting that i posted, i have every notes about it apart from the code so i thought i could make my own code using flowcode,But what i dont undestand now is how did that programmer make tha...

Re: Ac measurement up to 400 vac

Ok then i get you a transformer is a safe way to go that i know but expensive, anyway since u recomend it can u help with a full drawn diagram on paper and the calculations in flowcode calculator on how to display Ac voltage on lcd just help with diagram with all the components and flowcode calculat...

Re: Ac measurement up to 400 vac

Ok if that wont work advise me also on this second setting will it work, and if it will how do we go about the calculation to display Vin on the LCD?

Re: Ac measurement up to 400 vac

Yes sir you know am looking foward to making an ac voltage stabilizer but coded in flowcode because i just find my self liking flowcode very much so in my ac volt stabilizer am looking at 130vac to 280vac to give me an out put between (200 - 250vac) so me talking about 400vac (which is 565 peak givi...

Re: Ac measurement up to 400 vac

Thank you very much sir but also educate me here were i may be wrong 400 x 2 x √2= 1131
Where is the 2 coming from and what is it for i thought it would be 400 x √2= 565 peak volts only.

Ac measurement up to 400 vac

I got this circuit were gain is: Gain= R8/(R1+ R2+ R3) ; Gain= (22K)/( 1.2M + 1.2M + 2.2K) = 0.0091 And voltage out is: Eg: 220vac = 311 peak. Vout =0 .0091 * 311 = 2.8301 volt (peak output voltage) As you can see R7 resistor is used to increase DC voltage level op-amp output. Now output peak voltag...

Re: Dc voltmeter 0-55v

Ok it works fine in simulation but when i built it in real time and connected a 9v battery to be measured it showed me arround 4v and when i switched to calibration mode it could only go upto 4.99v and dvf did not go above 1 yet its supposed to go up to 11 and when i disconnected the 9v battery from...

Re: Dc voltmeter 0-55v

Then how will it affect the value of ADCvolt coz it needs to be that when ever an active low button is placed it enter calibration mode then turn 5k to affect values of measuredVoltage,after a required value is read on LCD,turn off the active low button and chip exits calibration mode and saves the ...

Re: Dc voltmeter 0-55v

Yes it must be from 0-11 but remeber the 5k variable pot on real circuit has a maximum input of 5v(VDD)

Yes u are right am using a mobile but ive seen one of your 0-15 voltmeter and there is were u did the math may u can help me from here 920 *5/(1023/100)*3 = 1380 am failing to know were u get the 100 in your calculation what is it please my math is not all that good
