Once this screen appears, the Current Error Time
n.
counter will begin to count. The Current Error
Time counter will continue to count until the
chamber temperature is within ± 0.5° C of the
Chamber Setpoint. The Accumulated Error Time
counter does not increment until the Current Error
Time counter stops counting. At that time, the
Current Error Time counter value will be loaded
into the Accumulated Error Time counter. If the
temperature or pressure inside the PAV goes
outside of the allowable limits, the Current Error
Time counter will reset and begin counting until
the temperature and/or pressure has returned
to within allowable limits, and the Accumulated
Error Time counter will again be updated. The
Accumulated Error Time counter will only update
after the Current Error Time counter has quit
counting.
NOTE: It is possible that the Current Error Time
counter will continue to count for several seconds
or more when the Chamber Temperature displayed
is within ± 0.5° C of the Chamber Setpoint. This is
normal and is due to the fact that the Chamber
Temperature display is 1 decimal point of precision
and is rounded up, while the error time is based on
3 decimal points of precision.
