46. ANALYZER OPERATION MANUAL Figure 3 5 SO Calibration Using a Permeation Tube Temperature control is the primary concern in using an SO permeation device as a standard SO source For example a change in temperature of about 0 5 C effects a change in the permeation rate of the device of about 4 For this reason it is important that the temperature of the device be maintained at a constant value within 0 1 and that it be closely monitored when the device is in use Generally the SO permeation device is housed in a temperature controlled glass container that has an entrance and exit port at opposite ends a glass thermometer accurate to 30 05 C can be placed beside the device to monitor its temperature A small fixed zero air or nitrogen flow about 100 SCCM that is maintained at the same temperature as the permeation device flushes the SO out of the device housing into a mixing chamber where the SO is diluted with clean dry zero air A valve e g a three way stopcock placed at the exit of the device housing may be used to divert the SO stream to a vent when clean air is required at the manifold for making the necessary zero adjustments to the analyzer To maintain the temperature of the permeation device within 0 1 C of the desired value the device and housing may be placed either physically inside a constant temperature chamber as shown in Figure 3 5 or they can be located outside the constant temperature chamber with the

56. O ANALYZER OPERATION MANUAL 2 4 Analyzer Calibration When the EC9850 analyzer is powered on for the first time the analyzer must be calibrated to ensure accurate SO measurements The analyzer does not require recalibration after further power interruptions or resets However if the instrument is transported to a new location or maintenance work is performed the instrument may require re calibration To determine weather the instrument requires a calibration a precision check can be performed as discussed in the following sections 2 4 1 Precision Checks A precision check is a Level 2 calibration as discussed in section 3 4 This means that the instrument is only checked against a know calibration source and is not adjusted A precision check can be performed either manually or automatically 2 4 2 Automatic Most modern air quality monitoring systems have data acquisition systems which can automatically initiate and record the results of a daily precision check The means by which the analyzer is externally controlled is via the 50 PIN IO connection or via the RS232 multidrop connection Refer to section 4 0 for more details on interfacing to these ports 2 4 3 Manual A manual precision check can be initiated as follows 1 Connect a source of span gas to the analyzer through the Auxiliary port see chapter3 for instructions on preparing calibration gas 2 From the CALIBRATION MENU set CALIBRATION tO MANUAL and CAL MODE to
