Adjustable start and stop voltages for decay tests A serial interface and applications software to control ionization tests from a computer The Model 288B has been improved to provide the following capabilities: The ability to resolve the plate voltage with 100 mV resolution ... -
Page 7: General Information
Section 2 GENERAL INFORMATION Model 288 performs manual or automatic decay and balance tests for qualification and periodic verification of ionization equipment. It then stores the results and balance averages for manual tests and complete automatic test sequences up to a maximum of 1500 tests. Temperature and relative humidity are displayed real-time and recorded with the test data. -

RAM/EE – The first screen under this option asks, “Clear all test data – Y/N?” A “Y(es)” response will permanently erase all accumulated test data from memory. The next two windows prompt a similar decision for whether to restore defaults to Group/Location names and test setups. These decisions should not be taken lightly as deletions are irreversible. -

Page 13: Programming Features For Manual Test
Confidence Test – One of the major weaknesses in all CPM’s has been the inability to properly verify the main function of these devices, DECAY. In all the existing instruments it is possible to test the plate voltage, timer performance and other parameters but not the actual decay function. -
Page 14: Automatic Operation
AUTOMATIC OPERATION: Once the desired test parameters are set up, the user simply selects the “start” button to begin the tests. All the parameters are shown in the automatic screen. Figure 14. Auto Sequence Test ___ From the MAIN screen, press AUTO: AUTO 06/18/08 This shows the... -
