a model # would probably have helped your causeanalog vs digital

go with the SMAN3, Russell Harju with Fieldpiece has always answered any concern I've had.i've got 2 of the testo 550,, good thing- because they alternate being sent back to testo to get repaired, after warranty is up, will probably 86'em.
Fieldpiece now has the SMAN3 in a blow molded case (haven't seen it-personally)
the supply house you get them from (whichever one) will make the experience good or bad...........
if you don't understand what you are measuring, stick with the analogs until you do,
go behind "techs" with digital gauges that can't see/understand what the gages are telling them, just because they don't understand what all those #'s indicate
also,,, "charge is good" is not appropriate..my reply to that statement (whether seasoned "tech" or not) is PROVE IT

personally, I'd lose the "edge", it's one of the biggest pieces of junk to come from carrier in a whilejust a little read
@ July 7, 2011 9:45 PM in Condenser fan motor?
from Fasco Motor FactsFACT Modern multi-speed motors are really not multi-speed,
but multi-horsepower. The speeds are simply taps at different
points in the coil. The higher speeds are tapped at a point with
fewer turns as compared to where the subsequent speeds are
tapped in the same coil. The more turns that are wound before a
tap is brought out, the lower the horsepower will be each time.
Obviously, the lowest speed lead is connected to the end of the
last turn on the coil. These added turns weaken the motor. This
field weakening allows the load to slow the motor down each
time a slower speed is selected. With no load mounted on the
shaft, as with a bench test, no difference between speeds will be
seen. If too strong a replacement motor is used on a unit, there
may be no appreciable difference when the speed is changed in
the unit. Remember, the motor relies on the load to slow it down
between the speeds. As an example, if a 1/2 HP three speed
motor is used instead of a 1/4 HP three speed, there might not be
any noticeable difference between Hi, Med, and Low.
NOTE: A motor nameplate showing 1350 RPM is a special design
and must be replaced with an OEM direct replacement. This is a
high slip 4 pole motor, which is not generally available in a general
line of motors. If one is available, it would be marketed as an OEM
direct replacement motor for a specific piece of equipment. These
motors are specially designed for a very specific load.

it does depend on what t-stat ypu are usingif O?B it's for reversing valve, engage in heat or cool
if the O and B are in different locations, you really have to be careful what you hook to
those terminals..........
