This output voltage is perhaps not too useful for meter calibration, but adding one opamp and a few precision resistors will give you 10 volts RMS which is a whole lot better. The frequency is set with two floating capacitors, so a four-pole switch is needed to change frequency. Also, be...
the air conditioner works fenumenal i was skeptical with some of the reviews and decided to try it i love it highly recommend now i havent needed to try the heater so cant comment on that one yet Kat 00 3 out of 5 stars review 7/7/2024 It wo...
I don't have a voltage connection (that would be for next time!), but I measure 48 cycles of current and compute the Fourier coefficients at 50 Hz. I'm assuming that if the load is not too reactive, the 50 Hz component of the current should be mostly in sync with the voltage.I a...
Well, I went with the low ball because I just needed the leak fixed and currently do not want to take out credit for a larger job. If they offered part of the $1,100 as a credit towards a water heater in the future, I would go with them. But since I felt a high pressure ...
trying different control modes. I can’t figure out how to set up this app without knowing that what it says it does isn’t what it actually does and some non-obvious way of fixing it. I’m sure it’s something to do with the light outlet, but I’d rather just not use it. At...
He does an excellent job, is very professional, and extremely knowledgeable. Ann Russell 00:18 27 Oct 20 We had them out for repair summer 2019. Fixed and told us AC was old and probably should be replaced, but heating unit was ok. Not wanting it to go out again in 2020, had them...
We got this after our old portable started crapping out on us, and not only does it assist it in its job, it's replaced it completely. Not just for the upstairs bedroom, but the entire upstairs, and even helps with the rest of the ho...
These precautions include, but are not limited to, the following: Power supply/AC adaptor • Do not connect the instrument to an electrical outlet using a multiple-connector. Doing so can result in lower sound quality, or possibly cause overheating in the outlet. • When removing the ...
Works well You must be within 10 ft or so of unit but it does work good. Sana Ur Rehman Dogar,2023/09/09 Doesn’t work It’s a scam or a trash, doesn’t work. I even tried from 1 feet Arial Lollipop,2017/04/29 This app is only to play with buttons. It does nothing at all...
A ductless mini-split is a type of air conditioning system that uses an outside condensing unit to HVAC Experts PTAC Specialist locally. The HVAC Experts PTAC Specialist is not delivered through ducts but through a wall-mounted or ceiling-mounted blower unit. Several indoor blower units can op...
