This could have been avoided if I had just pushed the LCD all the way in to begin with. Your name or email address: Electro Tech is an online community with overmembers who enjoy talking ca3162 datasheet and building electronic circuits, projects and gadgets.

Taking this into consideration ca3162 datasheet max input voltage of mV ca3126 the CA might not be exceeded when measuring the boiling temperature darasheet altitude. Thank you in datasheeg, Joshua in England View attachment View attachment This site uses cookies to help personalise content, tailor your experience and to keep you logged in if you register.

Any and all help would be appreciated. All questions will be answered promptly. Oct 22, Messages: Jan 12, Messages: I have attached the schematic that I used. Sep 11, Messages: The correct value ca3162 datasheet The temperature of boiling water decreases with increasing elevation. View attachment Here it is with the LM in some warm water. And can anyone ascertain whether I should try a larger or smaller value in the gain resistor if I need to try dayasheet new pot?

I am a new member, and first time poster. Even so, the application is a solar cooker, so it only ca3162 datasheet to measure temperatures between ca3162 datasheet room temp and or so.


Jan 26, Messages: So it took longer than expected but the learning curve was at work and you come away from each project datasheft lessoned learned beyond what the book covers. I lit up the cq3162 ca3162 datasheet digit decimal point by hooking it up to ground, and it magically made sense. Share This Ca3162 datasheet Tweet. I will update again with pictures. I also isolated pin 10 on the CAE so that it only connects with the LM35 and its own ground It was sharing a ca3162 datasheet and a connection cq3162 with another capacitor.

I replaced the battery. I may be off base with this but reading dxtasheet CA data sheet I see the max input as mV. I did’t want to force it at first, and later, I fell into the trap of not double checking it.

ReloadronJan 26, Log in or Sign up. Ca3162 datasheet ended up soldering two of my spare meter leads to the board to constantly monitor the LM35, so I could compare it to the screen.

Nov 10, Ca3162 datasheet Electronics Forum Circuits, Projects and Microcontrollers. Good going and pictures would be nice. No adjusting with either the zeroing pot nor the gain adjust pot can make it read zero ca3162 datasheet ice water and in boiling water.

I built ca3162 datasheet circuit on strip board, using a published circuit diagram. Ex Yorks’ Hants UK. No adjusting at the 10K pot will change this.

ca3162 datasheet I cannot tell wether it happens slower or quicker with more or less resistance. No, create an account now. Click here to register now.

Then after hours of adjusting, I ca3162 datasheet that the number one digit was not coming on sometimes. Do you already have an account? BoncukJan 26, The thermometer as assembled powers up and reads digits on the LCD display, and I can use the zero adjust pot to change the temperature. Could it ca3162 datasheet that a voltage divider is necessary, or could it be that this thermometer as constructed can still be adjusted to read in Datsheet Yes, ca3162 datasheet password is: I think that I spent over 40 hours on this project, and I am happy that it now works to my satisfaction.

However, the LCD races datashet in 2 – 5 step increments until it is well over the actual temperature. JimBJan 26, I did these things just to make sure nothing was back feeding anything else or making a weird connection. I made a substitution where Ca3162 datasheet is now a. ca3162 datasheet

I have seen ca3162 datasheet CA and CA used ca3162 datasheet a digital multimeter, and some of those diagrams use voltage dividers before they datasheet to the CA In summation, it is working perfectly, and much more brightly. Jan 4, Messages: Could it possibly be the. It still responds by increasing digits in hot water and decreasing digits in cold water, it just seems to be logarithmically off somehow.
