2. The Sample and Hold measurement mode is available to facilitate data recording when testing multiple packages or sites In this mode the analyzer draws gas for measurement over the user specified sample period 900141 product is shipped with the factory default setting of 15 seconds then turns the pump off and freezes the display The displayed values are held until the next measurement cycle is executed The UP ARROW button puts the analyzer in the Sample and Hold Measurement Mode and initiates the first test cycle Pressing this button will cause the analyzer to count down the sample time selected then turn the pump off and freeze the displays 3 4 3 When the button is pressed for the first time the analyzer will indicate execution of a sample period by flashing the display every second while taking measurements At the end of the test interval it will turn off the pump and freeze the displayed readings as described above Consecutive measurements may be taken by pushing the UP ARROW button again This process continues indefinitely until the analyzer is either powered off or set back into Continuous Measure Mode done by pressing the DOWN ARROW button Changing the Sample time from the factory default The sample time used in the sample measurement mode may be easily 6 6 adjusted by the operator from the factory default value This is done by first putting the analyzer in Continuous Measurement M

Port 9600 baud 11 7 2 RESET the CO2 andO2 Channel Calibrations to Factory Settings Use the UP DOWN Arrows If you suspect that the analyzer is operating incorrectly and has been previously mis calibrated you may RESET previous calibrations and revert to the as shipped factory calibration constants Use this procedure if calibration values have been saved but you want to restore default starting calibration values To do this simple enter the Calibration Mode as described above and then press the DOWN and UP arrows simultaneously for 1 second When CAL disappears from the display the Calibration Mode has been terminated and the analyzer calibration constants have been reset to the original as shipped factory values After the calibration constants have been reset the analyzer may be operated with factory calibration constants or may be re calibrated as described above The previous calibration values are permanently erased The factory default calibration values are used and stored in power safe memory for later use when powered down Consumables Spare Parts and Accessories The following spare parts consumables and accessories can be purchased from Bridge Analyzers Consumables P N Part Name Life 001015 1 16 Thk Sticky Nickel Septum N A 108126 Sample Filter 6 pack 6 12 months 001140 Oxygen Sensor 12 24 months Spare Parts P N Part Name Life 000617 Sample Needle N A 001370 Sample Line w

12. n gas usually does not contain any O2 The analyzer Low O2 calibration is used to set the zero reading of the O2 channel and is actually an O2 offset adjustment and is only active with O2 levels less than 2 000 When the indicated O2 is less than 2 000 the Low O2 calibration mode may be used to adjust the O2 reading to agree with the level of O2 in the calibration gas which is generally 0 000 This can be done on a gas mix containing CO2 but the presence of CO2 will not have an effect on low O2 measurement so N2 or some other oxygen free gas mix may be used If a small amount of O2 is specified to be present in the calibration gas the Low O2 calibration mode can be used to adjust the analyzer to correctly read the trace O2 value Conversely because the O2 sensor is automatically span calibrated to ambient air every time an analyzer Zero is performed Hi Span calibration of the O2 sensor is not generally necessary unless the customer wishes to have High O2 substantially above 20 60 process gas read correctly The High O2 calibration mode is activated only at O2 levels above 2 000 When the non active O2 calibration mode is selected during calibration it flashes indicating that it is not usable NOTE Hi Calibrating the O2 channel will cause the analyzer to read other than 20 60 when it is Zeroed on ambient air 6 1 Customer Span Cal and Cal Verification Procedure Power up the analyzer and pe
