Subject: PM-128 meter


I just got myself a pm-128 voltmeter to make into an O2 analyser.
Anyone done that before? What is simplest solution so that 50mV 
from the sensor reads 100? I'm looking into making a simple DC voltage 
amplifier using an op-amp. Is there something easier,like shifting the
output of the ADC by one bit? 

                                                                    [\]
