Once Calibration menu option has been selected, the analyzer will purge itself,
perform a zero, and then proceed to the next step. When zeroing is complete, you will be prompted to
Enter Tag Values. The tag values should be entered just as they are on the calibration bottle. You are not
required to calculate the PEF value for HC. Instead enter the propane value and the analyzer will
internally convert it to a hexane HC value. When entering tag values for CO and CO2 are entered are
percentages. For HC and NOx, values are entered as ppm. Any gas you do not wish to change the
calibration on should be set to ¯ ¯ ¯ which indicates no value change. O2 is self calibrating on atmospheric
O2 (air). To enter the tag values of your calibration gas, use the GAS key to select the gas. Press + to
change the value of the highlighted numeral and select the
NEXT
key to advance to the following
numeral. When finished, press Continue to advance to the next sequence serene. The screen will prompt
you to Turn Cal Gas On and all the values will be shown below. Once the cal gas has been turned on, wait
for the values to rise and stabilize then press Continue. This is when the analyzer performs its actual
calibration. Do not disturb the analyzer during this period or the accuracy of your calibration could be
jeopardized. When calibration is complete, you will be prompted to Turn Calibration Gas Off. When this is
completed, press
