<Calibration Procedure>
Perform a calibration using the procedure shown below.
Warm up the gas monitor for 60 minutes or longer before performing the fresh air
adjustment to ensure more accurate adjustment.
The gases may be introduced in random order.
 Combustible gas (%LEL)
 O
2
gas *1
 CO gas
 H
2
S gas
 100% N
2
gas
(If the measurement is done in inert gas, use the inert gas for zero adjustment.)
 Combustible gas (vol%) in N2 balance
(If the measurement is done in inert gas, use the span gas for high concentration
combustible with inert gas balance.
WARNING
About the calibration gas
Calibration gas is a hazardous gas (toxic, oxygen deficient, etc.). Handle the gas and related jigs
and tools with due care (e.g., the gas must not be inhaled).
About the calibration location
 Perform the calibration where no silicon, organic solvent, spray can gases, etc. are used.
 Perform the calibration indoors at normal temperature without remarkable fluctuation (within ±5C).
 Perform the calibration in an exhaust booth.
CAUTION
Do not connect any tubing to the GAS OUT fitting during calibration.
