Pressing SET CLASS brings up a screen listing all applicable FS 209E and ISO 14644 classes Pressing the key of the desired class will cause the key to turn green enabled and any key previously enabled will turn yellow disabled ISO 14644 allows the exclusion of a measurement from the ISO calculations when the 95 Upper Confidence Limit fails due to an outlier that skews the standard deviation used to calculate the 95 upper confidence level The ISO standard does require that the suspected cause of the outlier be documented When the ISO EXCLUDE LOCATION key is pressed the ID menu appears If one of the locations is to be excluded from the calculations highlight the location on the ID list then press EXIT If you do not want to exclude any data press NO EXCLUDE which will return you to the previous menu screen without excluding any data This feature is only available for ISO 14644 calculations Once the exclusion has been made the report can be printed by pressing 1SO 209E and then PRINT from the following screen 2 14 2 Settings A printout of the settings can be useful They can be used to maintain a record of different program settings Such a record becomes valuable if a program is cleared from memory A printout of a program s settings can be used as a permanent record of the settings to be kept with the data collected using a given program The printouts can also be used to see all settings at once without having to

9. Place that side of the battery into the compartment first with the Molex connector resting on the left recessed part of the battery pack so that there will be room for the connector within the battery compartment Push the battery fully inside the compartment with the Molex connector resting on the angle of the battery pack Make sure that the battery wires are not pinched against the metal enclosure or the battery door Once the battery is properly installed replace the compartment cover and secure the door by turning the 4 turn screw until it locks 6 1 2 Fuse replacement The AC line fuses are located in the power entry module There is a lock that is released by pressing down on the tab in the center of the fuse module The fuse module projects out from the power entry module and can be easily grasped between the finger and thumb and pulled from the power entry module The fuse holder contains two 5 X 20 mm fuses Use fuses identical to those installed if replacement be necessary 6 1 3 Long tem storage Nickel Metal Hydride batteries like other types of batteries will discharge gradually when left in circuit A deep discharge of the battery could damage it When stored for extended periods particularly if the unit will be stored for 3 months or longer the battery should be disconnected To disconnect the battery lay the unit on its back with the AC power cord disconnected and open the battery compartment door The door is S
