I have breadboarded a voltmeter circuit using ICL7107. When I tested it, on power on itself it shows readings like 340 and 120 instead of zero.. My doubt is if this IC had been affected by electrostatic charges during handling, what would happen to the output? Due to breadboard limitations, I guess some component is not seated perfectly.. It has about 50 wires running to 4 seven segment displays... Should I go for soldering this and what could be its problem and how to solve it??? Varying the variable resistor doesnt help..
