2. Maximum test time was extended to 255 min-
utes.

4. Asphalt content expressed in percent loss on

Version G: Several new operating features were added.
They include:
1. Programmable time/date function. (This allows
operators to program the NCAT to begin heating
up automatically at a specific time/date.
Operators can arrive to work in the morning to
find the NCAT unit all ready up to burn tempera-

a 24 hour time format. The unit must be in the
inactivity mode of operation in order for pro-
grammable timer to function properly.
2. Inactivity mode. (If no keys are pressed in 4
hours of operation, the display will read “In Ac”
in the chamber temp window. This feature will
benefit operators with NCATs in remote loca-

power off unit in times of non-use.) The unit
must be in the inactivity mode of operation in
order for programmable timer to function proper-
ly.
3. Test interrupt/Power interrupt. (If power to the
NCAT is interrupted during a burn and then
restored, the furnace will continue the test, pre-
venting smoke buildup in the lab. The burn ticket
will print “Results Invalid” with “Test Interrupted”.
4. Auto-Shutdown Mode. Software can be toggled
by performing a hidden temperature key routine
to toggle between Auto and Manual mode of
operation. In Auto mode, the unit will recognize
the endpoint of a test, stop the blower motor
and print the results. The unit will beep once
every minute to alert operator the test is com-
plete. In Manual mode, the unit will recognize
