Signal diodes also have many uses in processing signals in electronic equipment; they are used to obtain the audio and video signals from transmitted radio frequency signals (demodulation) and can also be used to shape and modify AC signal waveforms (clipping, limiting and DC restoration).
What is acceptable air conditioner outlet temperature? I have a 1996 Nissan Maxima. It was about 95 degrees today (measured with my own thermometer not what the weather report says), and my air conditioner outlet temperature was reading about 50 degrees. that would be temperature differential of about 45 degrees. I had the fan on second lowest out of 4 settings and on recirculation.
Here's a quote taken from a previous thread regarding the coolant temp light staying on more than a few seconds after startup: XterraVersa wrote:This is normal for all cars. Most take a few minutes to warm up the coolant even in 100 degree temperature. I am not sure with the Versa, but normal on my Xterra is 170.
