Appendix C
Calibrating the Innova SV and FV
The Innova automatic calibration (AUTO CAL) displays all active sensors on
the display screen at the same time. You can calibrate all active sensors
simultaneously using a gas cylinder available from Thermo
Fisher Scientific.
WARNING
The instruments is calibrated in the methane elimination (ME)
mode using the %LEL range mode. The instrument is calibrated
with hexane. To measure other gases, use Table B-2 in Appendix B.
The concentrations set in the Auto Cal Gas Value screen must match the
multi-gas mixture, see Chapter 4, User Program, Setting Auto Cal Gas
Values.
NOTE
The Innova Soil and Fuel Vapor Monitors use a 3-foot, teflon-lined
hose to minimize absorption of hydrocarbon vapors. Use of longer
hose lengths is not recommended.
Auto Calibration
WARNING
Calibrate the Innova in a “fresh air” environment (environment
known to be free of combustible and toxic gases and of normal
oxygen content).
NOTE
If you use the automatic adjustment method to calibrate the sensor,
make sure the gas cylinder contains the same concentrations of the
target gas as the values set in the
“AUTOCAL GAS VAL”
menu, see
Chapter 4, User Program, Setting Auto Cal Gas Values.
