Appendix C

**Note** The elevation correction chart supports new style Meth-

ane ODORATORS only. Instruments manufactured

before July 1997, that have not been upgraded or cali-

brated to a methane reference other than 1.00% will not

use the elevation correction charts. Consult the factory

for using older style ODORATORS at elevation. To

identify an ODORATOR’S style or to tell if an upgrade

has been performed, check the top panel to see if there

is a snap-in bezel or a clear window in the overlay cov-

ering the display (“LCD”). Older style ODORATORS

have a snap-in bezel over the LCD. ODORATORS not

calibrated for 1.00% methane have correction charts

for that gas or reference level and can be identied by

the chart as the reading and actual values will be equal

at the reference level.
