mga master may ask lang po ako about sa kit na power analyzer:

1.) alam niyo po ba kung paano pataasin ang Real Power ng Power Analyzer from 2200w to 10000W?... parang maliit po ata maxado ang 2200 W para sa mga load na gagamitan ko,.
2.) Pwede po makahingi ng data kung paano na formulate ang mga data ng power analyzer?
3.) Paano po ito e calibrate, mukhang iba ata ang ouput?
4.) Any suggestions po if paano ko siya ma test if calibrated or accurate tlga ang output data niya..

maraming salamat po sa mga nag basa

sir may questions lang ako sa power read ng Power Analyzer kit. Nag test po kasi ako ng 20Watts GE na bulb, bakit po sa reading umabot siya ng 320Watts? is there something wrong with the computation or the GE bulb?

malamang sa computation lang yan. Make sure tama unit mo before multiplying.

kasi ho, direct ko na connect between power analyzer and MCU(PIC16F877a) via UART then display sa LCD, then then i tried to input the 40Watts GE bulb, then ang reading 320watts, pati ung electric fan umbot ng 400w sel#1 pag Sel#3 aabot ng 740watts, tapos ung sony erricson na charger umabot ng 42 watts.. naga doubt lang po ako sir, bakit tataas ng reading.. sir ask lang po ako, REAL POWER po ba ang watts na gamit ng mga electric components?..

Bro, I sent you already the vb2010 gui I made for the e-gizmo power analyzer. Check mo muna dun sa pc/gui kung ganun talaga yung output.

Yung raw data, ayan yung exact data na galing sa power analyzer, it will also be the same thing you would see if you use hyperterminal instead.

Kung mataas talaga yung reading at hindi kapanipaniwala, return the power analyzer to e-gizmo, baka kailangan ireflash yung f/w ng zilog mcu or baka may na loose connection na wire. May wire na manipis sa ilalim nung coil (current sense resistor), baka loose connection na or natanggal.

sir figure 3b or 3c po ba gamit mo na connection dito from the manual?..
sir ano po ba ung current watt-hour jan?.. may computation ka nyan?..

sir pwd ba serial to usb ggamitin ko?.. vga pala itong port ko.. paano configure ang com port ng usb?
eto po ang pix, nag papayad na ata ang imageshack hindi na makuha ang direct link.. http://img809.imageshack.us/i/dsc01047z.jpg/

mga masters ano po problema nito nag load po ako ng electric fan http://img576.imageshack.us/img576/4008/questun.jpg

gamitin mo yung fig. 3c sa manual.

when you plug the usb-serial adapter, check mo sa device manager under ports kung anong port number ang lalabas. then when you use my gui, just select the com port na lumabas sa device manager.

ahhh.. ung 3b kasi gamit ko ito ang lumabas ??>

?

Oj0vO · « **Reply #12 on:** February 14, 2011, 08:21:53 PM »

ito pa lumabas nung gamit ko fig. 3b

i think sir mukhang sobra ng Wx10 ang reading ng true power na PowerANalyzer kasi instead of 32Watts ung bulb nagiging 320 watts, nakakapus na ako sa oras kung ipapadala ko pa sa Egizmo, kasi mindanao po ako, what if reprogram ko na lang sir, divide ko by 10?...

sir paano ko pag sabayin ung display sa PC visual basic at MCU through LCD?... dba pull up ung sa MCU then ibang connections sa Serial.. Paano kaya to sir?.

mukhang mali ang baudrate ah

ok na po ito, lumabas n po ang output, ang problema ko n lang ung reading ng power kasi masyadong mataas...

you can use fig 3b for that but use 5V only for the pullup. tapos tap ka na lang ng waire from pin 1 to the mcu at ground.
