        PCA xx
      WARMUP yy
Where: xx = Instrument Model Number
yy = Counts down from 60 seconds
As soon as the 
 
 key  is  pressed, the instrument’s serial number and
software version number are displayed for approximately 3 seconds. To
continuously display these items, hold down the 
 
 key  at  start-up. The
warmup cycle continues after the 
 
 key  is  released.
The Warmup Screen is displayed during the analyzer’s 60 second warmup
cycle, during which time the “Warmup” value (yy) counts down to zero.
After the warmup cycle is complete (and if the unit is working correctly)
the instrument will flash  
NO ERRORS DETECTED and go directly to
the Combustion Test Screen (Section 4.7). If there is a problem, however,
with one or more of the sensors, the Sensor Status Screen (Section 4.6) is
displayed with error message(s) appearing at the bottom of the screen.
