You adjust the reading to attempt to get them to the same scale, then
apply some loose fuzzy logic - don't worry about sharp boundaries.
If the bg is 59 or 62 don't make a big change in the reaction based
on a small change in the value.  I adjust amount of carb (sugar tabs)
based on the value and what was going on before the low and what I
anticipate for the next hour or so.  I adjust the extra bolus amount
using a somewhat linear function - easier to do now since the pump
allows me to use bolus in tenth of a unit increments.

You should attempt to use the same meter most of the time so you get
accustomed to it.  I use three meters regularly, but every few days I
parallel test on all three to get a comparison figure.  I can then
see how the readings relate and how to manage the data they provide
in my decision making.  The key is to get familiar with your meters,
your protocol and how the particular meters perform.
