Hi. I'm looking for any documentation for this display. It has being pulled off from a energy meter type Nemo 96. A traditional web search doesn't return any usable results. Thanks
Hello experts, I am working with pi3, 3.2 inch touch LCD and temperature sensor. I got output for temp sensor, touch LCD. Now i have displayed my sensor reading to the touch display in terminal . But i need to display the temperature reading in GUI like graphical thermometer or analog speedo (...)
Sorry for the long post I have a UT60E meter which sends out RS232 data to serial port and would like an Arduino to receive and display the data on LCD(with the idea after to send via NRF24L01'S) for data logging to SD card, Now I know how to do the SD part, But fairly new to Arduino and don't really know how to do it, I found a couple of web sit
hello everyone I m designing a metering circuit based on a microcontroller and 7 segments, which will be used as display the value of a certain physical variable in industrial process. my problem now is which power supply to choose. I thought about transformerless power supply, but I think it will cause heavy losses and decrease efficiency ,
Does the meter display any status message, to indicate it has received communication? Or sending communication. I have never used this type of meter so all I can think of are general questions. You'll need to test any commands, in an effort to find anything that works. Start with the most basic commands. Watch for any sign that you achieved (...)
hi, i need to measure resistance of a 1m(minimum) length 0.2mm(minimum) diameter copper cable resistance with 1 micro ohm resistance least count. is there any commercial product available for this task. I have a 4 Wire Low Ohm meter using a 3 1/2 digit display, so it will only measure to .001 of an ohm. If a
Hi! I got a nice Digimess DM200 bench dvm (Mastech M9803R clone) sold as seen on ebay but it looks like the NJU9210F dvm chip has died - no display, backlight works but nothing else! Can anyone point me in the direction of any new (preferably less than ?20!) cheapo DVMs that use '9210F's I can use for the chip and any other odds and ends I mi
i thought i posted this but not seeing my post so excuse me if i am posting twice. I am trying to measure a current consumption of my circuit and i am putting the voltmeter in series on the positive terminal of the power supply and getting a 1.4mA rating. The issue is that the circuit is using a display and the display manufacturer says (...)
Hi! I may be wrong, maybe it's a faulty batch of DMMS, but "1" on the display can mean over-range. Are you measuring something under 200mV on the 200mV scale? If what you are measuring is over 200mV on the 200mV scale the DMM will say "1" "OL" or something like that.
hello sir i am doing my project on embedded pic controller 16f877a and i have got the meter for reading the solar panel data such as volts ,amps, freq etc .and this data is taken from MODSCAN software ,but i want to use or import the data from MODSCAN to MATLAB please do tell me the procedure to import the data and display in matlab.
Use a Battery and a variable resistor to set the current and to simulate changes in sunlight. Use a watt meter to display the power.
hello... i am working on flow meter project. in which i want to display total liter of water. i am just increment variable value on each pulse. i define variable for it "unsigned int TOTALIZATOR", my microcontroller is ATMEGA32A. My problem is that when i am trying to display this variable value in 16x2 LCD display, (...)
I have analog circuit that generate several type of waveforms (sine, tri, and sqrt) of frequencies from 10Hz to 1KHz trying to display the current and the frequency both on a LCD or through usb port in a PC. any selections
Dear all, O need to design digital meter that display current and voltage of three phase systemk 380v-400v please guide me how to make the connection and isolation ,i think aboit cts but not sure the way i will do it I am using pic18f and mikroc for pic, please post some link if possible thanks in advance
hello, Give more details.. what is your full scale of milliamp for 5V on RA3 ADC input ? with ADC 10 bits => you will get 1024 pts for the full scale... How do you display the result ? UART -> RS232 -> terminal or on LCD 2x16 car or ?
I build a poptronix some years ago and it's still working I changed the output because I didnt have an analog meter so I use a simple LM3914 and a bargraph display module, I copied the datasheet example. and it works fine. here is the original poptronix pdf, along with tons of others esr meters schematics (I did not try them all...) [URL="kr
I am writing a program which can take the analogue voltage reading and use adc to convert this signal into digital signal and display In terms of digital values. Initially I was using a digital lcd and displayed the above mentioned data on lcd. Now I need a program which can display the data in the form of a dial (gauge) on GLCD with a (...)
What can a dual display meter do? and what are dual display meters used for mostly? to do what kind of measurements?
Using C language: Develop a C program to turn off/on the analog meter. Develop a C program to vary analog meter from minimum value to maximum upon the key press. develop a C program to display the status of panel meter in LED. it would be nice if somone could help me out with the source codes as i am a beginer. Thank (...)
Hi all fellow electronics engineers. We are currently working on a two-display ARM processor solution and have finished our PCB but seems to be having some issues with the cabling. Our current configuration consists of a single SSD1963 LCD display connected by a 1 meter long 40-pin flat ribbon cable. The display doesn't (...)
