1. 15 March 2001Absorber Review Meeting at NIU1 DAQ for Pressure Test, and later... Michael J. Haney University of Illinois m-haney@uiuc.edu

2. 15 March 2001Absorber Review Meeting at NIU2 In Hand at UofI 1 GHz PC, 512M RAM, 20G disk Labview, NI-DAQ 3 National Instruments PCI-MIO-16E-1 –1.25 MS/s, 12 bit ADC –16 SE / 8 Diff analog input channels –100mV - 10V (FS) programmable gain range –  11V max CM;  25V OVP (on)

3. 15 March 2001Absorber Review Meeting at NIU3 Enroute to UofI National Instruments PCI-GPIB –and cables for 3 peripherals GPIB software Labview.VI’s (work in progress) –multichannel logger –file reader

4. 15 March 2001Absorber Review Meeting at NIU4 Enroute (elsewhere) Keithley 220 current source Keithley 7001 switch Keithley 2001 multimeter –all are GPIB peripherals ?

5. 15 March 2001Absorber Review Meeting at NIU5 DAQ Plan for Pressure Test every millisecond –read (up to) 24 stain gauges –via PCI-MIO-16E-1 boards –common-mode permitting... every second –read strain gauges, pressure, flow –all (40) channels –via Multimeter/GPIB

6. 15 March 2001Absorber Review Meeting at NIU6 DAQ Plan for Pressure Test (continued) Spool everything to a file –10 GB / (24 * 12 bits * 1 KHz) = 77 hours –“start” and “stop” are moot... Analyze later –find quasi-static measurements between fills –look for vibrations –examine rupture
