8530 Shatterbox Manual 100713 abridged - SPEX SamplePrep

5.0 OPERATION8530 ShatterboxThe following sequence is typical. It supposes familiarity with the chief features of theShatterbox, as described in “SETTING UP.” First, these cautions:Never operate the Shatterbox without a grinding container and friction disc clamped firmly inplace. (If it is necessary to run the Shatterbox without grinding a sample, remove the grindingelement(s) from the container.) Never remove the access panel in the back of the cabinetunless the mill is first unplugged.1. Switch the power on. The timer display will light up. Initially it will flash the SPEXSamplePrep logo and then display SPEX SAMPLEPREP/8530 SHATTERBOX, but this willshortly change to the default timer setting of 3:00.2. Program the timer, using the buttons immediately below the numerical display. The lefthandpair of buttons controls the minutes, and the right-hand pair of buttons controls theseconds.3. Load the grinding container with sample. If running the Shatterbox without grindinganything, remove the grinding element(s) from the container. Clamp the container into thecapsule retainer. Make sure that the friction disc is properly placed and the grindingcontainer is firmly seated. If the clamp is properly adjusted, the clamp lever should worksmoothly with some resistance at the top of its arc, but you should not be able to rotate thecontainer in place once the clamp lever is down. If the clamp is too tight or too loose,adjust it.4. Shut the lid, and press the start button. There will be a brief pause while the lid locks down,and then the Shatterbox motor will start. As it runs, the timer display will count down theminutes and seconds remaining, in 5-second increments. When the timer reaches zero,RUN COMPLETE will appear in the timer display for five seconds while the lid remainslatched; this gives the grinding mechanism time to slow down. Then the timer setting willre-appear and the lid will unlatch, with an audible click. Always wait for the lid to unlatchbefore opening it.Open the lid, unclamp the grinding container, and remove it for emptying and cleaning.If ERROR: LATCH FAILURE is displayed instead of numerals when the start button is pressed, theinterlock has not properly engaged. Clear the timer by pressing the stop button, and correctthe problem.Page 12 of 28 SPEX SamplePrep LLC January 2010
