The following paragraphs provide step-by-step instructions for verifying the operation of 
your PI-SCX system. The intent of this simple procedure is to help you gain basic 
familiarity with the operation of your system and to show that it is functioning properly.  
The procedure does not require an X-ray source.  
Once basic familiarity has been 
established, then operation with other operating configurations, ones with more complex 
timing modes, can be performed.   
Once the PI-SCX system has been installed, operation of the camera is basically 
straightforward. In most applications you simply establish optimum performance using 
the 
Focus mode (WinView/32), select full frame, set the target camera temperature, and 
watch the dark charge decrease as the CCD temperature approaches the set temperature. 
Cabling 
If the system cables haven’t been installed, connect them as instructed in Chapter 4. 
Getting Started 
1.  If the system is water-cooled, double check that the circulator is filled with a 
50:50 mixture of ethylene glycol and water and that the hose connections are 
secure. When satisfied that these requirements are met, do the following. 
 
Turn on the circulator. The circulator will power up and begin pumping 
coolant through the camera. See the circulator instruction manual for 
detailed information.
 
 
Inspect the coolant hose connections to be sure there are no leaks.  
 
Turn on the refrigeration, if this feature is available, and set the coolant 
temperature (+5° for PI-SCX:4096  with ≤1.5:1 ratio and PI-SCX:4300, 0° 
for PI-SCX:4096 with >1.5:1 ratio, and +25°C for other PI-SCX models, 
unless otherwise specified). The compressor will start and cooldown will 
begin. 
2.  Verify that the line-voltage setting of the ST-133 is correct for the available 
power and switch ON the ST-133. 
3.  Turn on the power at the computer and start the application software 
(WinView/32, for example).  
Setting the Parameters 
Note: The following procedure is based on WinView/32: you will need to modify it if 
you are using a different application. Basic familiarity with the WinView/32 software is 
assumed. If this is not the case, you may want to review the software manual or have it 
available while performing this procedure. 
Set the software parameters as follows: 
Environment dialog (Setup|Environment): Set the DMA Buffer size to 
32 Mbytes (96 Mbytes for PI-SCX:4096), reboot the computer for this memory 
allocation to be activated, and then restart WinView.
