To check and then set the IRGASON zero and span, follow the steps below:
1. Remove power from the EC100.
2. If not already done, clean the windows and snouts with alcohol and a non-scratching tissue
or cloth.
CAUTION:
Make sure the alcohol and any residual water completely evaporate from the analyzer
before proceeding with the zero-and-span procedure.
3. As shown in FIGURE 9-4 (p. 37), position the IRGASON zero-and-span shroud over the
upper and lower snouts. To do this, twist the two ends of the shroud together to minimize
the length of the shroud. Make sure the rubber seals on the ends of the shroud are clean
and in good condition. Position one end of the shroud over the lower snout and twist the
top part of the shroud, allowing it to extend and cover the upper snout; while doing so,
avoid making contact with the sonic transducers. Continue twisting the shroud until it is
fully extended and covering both snouts. Twist the shroud so that the gas tubes and
temperature thermistor cable are directed towards the back of the sensor. Hang the tubes
and cable over the trunk of the sensor to alleviate any strain on the optical arms. See
FIGURE 9-4 (p. 37).
