C7 and C6 are nF filter capacitors not shown in schematic 3 years ago. There is given for DC voltage measurement,is it possible to measure for AC also or any modifications are required please give me suggestion.
For calibration, power up the circuit and short the input terminals. So you need a symmetrical power supply like the one here: Thanks for letting me know 3 years ago.
These are the input cs7107go the IC as you can see from its diagram. On the datasheet page 4 you can see the configuration for mV full scale. Admin i build this project together with your ct power supply but i have a little problem.

Thearmocouple sensor connect to The voltage to be measured is applied across points 1 datahseet 2 of the circuit and through the circuit R3, R4 and C4 is finally applied to pins 30 and 31 of the IC. How cani get -5V from my o-9v adapter?????? Feel free to send your PCB image to john circuitstoday.
It has been designed as a panel meter and can be used in DC power supplies or anywhere else it is necessary to have an accurate indication of the voltage present. Then a known reference voltage of opposite polarity is applied to the input of the integrator and datashet to ramp until the output of integrator becomes zero.

Leave a Reply Cancel reply Your email address will not be published. Kindly go through the following datasheet for 0 — 20VDC FS you have to use potential divider in the input. Audio oscillator circuit Simple function generator circuit Digital thermometer circuit Capacitance meter using LM Frequency to voltage converter using LM Can I use this circuit to measure V AC?
Audio oscillator circuit Simple function generator circuit Digital thermometer circuit Capacitance meter using LM Frequency to voltage converter using LM We recommend: Please double check connections and input voltage ripple. Its the trimmer potentiometer for calibration! DO NOT use soldering flux apart from that which is already included in your solder. Can I measure AC voltage with this, pls help 3 months ago.
Assemble the circuit on a good quality PCB. Hi Mahamoud please go through the intersil datasheet for your requirement http: On some applications negative supply can be omitted. The difference with is that has a hold pin to enable LED display freeze function. Use RS website for data sheets.
Will be very grateful. I assembled this circuit few years back and it is still working fine. Can you help me with a schematic diagram of a digital meter that can measure ampere 0AA pls. At the end of the preset period the integrator is fed with an internal reference voltage and the output of the circuit is gradually reduced until it reaches the level of the zero reference voltage.
The process taking place inside our ADC can be stated as follows. If nevertheless you have to use extra flux, as it is the case when you have to tin copper wires, clean it very thoroughly after you finish your work. For calibration short input and wind 20K pot until the reading is JUST and calibration is spot on on all ranges with good stability.
In the above circuit the maximum reading can be The working of this electronic circuit is very simple. And how will it affect the datashheet
Right most three displays are connected so that they can display all digits. In order to solder a component correctly you should do the following:. The IC includes internal circuitry for seven segment decoders, display drivers, reference voltage source and a clock.

Hi, I have assembled all the parts as per the diagram. How would you supply -5v to the IC? To find out the correct PCB dimensions you have to print it some times at different scales and try to fit the IC on the print.
Are you shure that decreasing the value for R4 you increase the range? Can the wise men in electronics guide me to any schematic, showing how to connect this display or any other to a zero to 30 v current limiting power supply I built recently. If the tip cannot be cleaned, replace it. The tip should be fine and must be kept clean at all times. So avoid touching the IC pins with your bare hands.
In detail the circuit works as follows. This work is not very difficult and if you stick to a few rules you should have no problems.
