hi paul,
oh, please don't blame atven, he is a super nice guy. it is just that i find it confusing.
perhaps, you misunderstood me. i mean, the new model ppp. there is no trimpot whatsoever.
atven's manager told me to press both the mode (up) and mode (down), then press the power up button, followed by display button. the output voltage will show up, and then i would use the mode (up) or mode (down) to adjust till 240v.
but when i powered up again, it drops to 233v. i also notice there is a "CUT 12V" reading on the display. btw, the input voltage is 245v.
what's happening?
thanks.
I don't mean to blame Atven at all - I was just responding to your comment about him. Atven's the nicest man on the planet actually.
There is a trimpot, trust me. The method that the tech is describing is not correct. What he is telling you to do will only mess up the calibration of the PPP metering system. What his is telling you to do is a method we use to calibrate the unit and does not affect the operation at all.
Turn the PPP upside down. Look at the bottom, near the front panel. Look carefully, you will see the trimpot. It is inside a hole
got it! piece of cake ;-)
but i have played with the "calibration" using the method that the tech manager told me, any issue with that?
thanks for your super prompt reply, paul!
Well, I don't know how much you changed the calibration. It is only the meter we're talking about so from a performance standpoint, no worries. Someday, you may want to check the meter accuracy against a voltmeter to see how close it is.
hi paul,
the difference between setting the output voltage from 230v to 240v is drastic! with 230v, music is lethargic; with 240v, music comes alive! i believe ppp is catered to countries where voltage is 230v?
i am going to tell atven tomorrow; i need him to buy me lunch for discovering that ;-)
thanks to you too, paul.
