is done in a particular way, and why it is done at
all, and why it can't be done more efficiently,
if it must be done at all."-- T.J.Watson
No.(well,you will not -damage- the cell,just alter(screw-up) it's
calibrated voltage)
You need a very hi-Z meter(=/> 100Meg) to avoid disturbing the voltage.
SC's were originally measured using the differential voltage method,using a
adjustable voltage source and a null meter.(At null,impedance is extremely
high,theoretically infinite)

The small current drawn will greatly affect the accuracy of your
measurement, and probably affect the cell. You should adjust a
precision power supply such as the HP 6111 to the cell voltage, then put
your microvolt meter between the cell and the 6111, and adjust until the
6111 is the same voltage. Then use the 6111 for your measurements. HP
6111 and similar precision PSes go for $40 to $100 on Ebay.
