Setting the Timer
When power is switched on, the timer will first display the SPEX logo, followed quickly by:
SPEX SAMPLEPREP
8530 SHATTERBOX
The timer will then display the default timer setting of three minutes (3:00). Assuming a
grinding container is clamped into the capsule retainer and the lid is down, pressing START will
initiate a run of 3 minutes. First there will be a delay of several seconds for the lid latch to
engage, then the timer will start counting down in 5-second increments: 2:55, 2:50, 2:45, etc.
Every time power is turned off and back on, the timer will revert to the 3:00 default setting. To
keep another timer setting, leave the power on. If power is not interrupted, the timer will
display the most recently programmed setting.
Set the grinding time with the four buttons below the timer display. There are up and down
buttons for minutes, and up and down buttons for seconds. The MIN buttons will change the
minute setting 1 minute at a time, and the SEC buttons will change the seconds setting 10
seconds at a time. 10:00 is the maximum running time; increasing the minutes setting past 10
will take the setting to zero. 50 is the maximum setting for seconds; increasing the seconds
past 50 will take the setting to zero. If a button is pushed and immediately released, it will
change its setting by one unit.
