But why pay that much for an antique, low spec, low performance, device?, when you can get much higher spec, better performance, opamps for less money?. The TL07x or TL08x series are cheap and just so much better than the crappy old 741- the 741 was a great device back in it's day - but it's day was just so long ago (probably before most members on this forum were even born!).
I don't think you want to use pins 1 and 5 to correct offset in another device. The offset circuitry in the 741 is there to correct op amp input offset voltage. Adding input offset to the op amp to correct for the offset of an external device will make the op amp's input offset temperature coefficient worse. Also, I doubt you could even get 0.2V of offset range.
You can add an offset adjustment to the single op amp noninverting circuit that Gramo posted, but the offset adjustment affects the gain unless you add another op amp to buffer the offset adjustment pot. I would probably just use two cascaded inverting stages, with the offset adjustment added to one of them.
Paul2000, is your offset 0.2V before the gain stage, or after it? How stable does your zero point have to be?
A 741 opamp has an input offset voltage of only 7.5mV max and its offset adjustment might adjust for 15mV. It certainly won't adjust for a 200mV error somewhere else.
Maybe the resistance of the sensor is very high and the input current of the opamp is creating a voltage drop? Then an opamp with FET inputs like a TL071 will fix it.
