Look up the readily available data sheet for these devices 7106 and 7107 (one is for LED the other for LCD)

The data sheets give aplications data for designing 3½ digit voltmeters etc...

Dear Friend,

you could find the details for the multimeters and get inspired from the following.

Rishabh Instruments, a nasik based company, i suppose, is the worlds leading manufacturer of the Analog panel meters and it is also engaged in manufacturing of the digital instruments for easing the daily tasks of people like us.

Now i have herd that they are representing Gossen Metrawatt of Germany and METREL of Slovenia for the marketing and servicing of the same in India.

I have found the websites of all the three companies and i am glad to tell you they are:

www.rishabh.co.in

www.gossenmetrawatt.com

www.metrel.si

I have bought the multimeter from this company and i was amazed with the performance of the same. Rishabh provides a very wonderful after sales service for all its instruments and now i came to know why they claim "German Quality products at Indian prices". Isnt that wonderful. I have ccordinated with a lady there at marketing@rishabh-instruments.com and spoke to her on 02532202160 when i had purchased the meter.

Have a nice time...

you can use this IC: ICL7135, 4-1/2 digit, you must use another hardware but is simple
