Drucker Diagnostics Model 842HS Centrifuge - Manual (Page 10)

The Hematofuge 842HS centrifuge is capable of storing up to 10 user-defined presets.These
memory presets contain all of the settings needed to define a specific run, (run time, speed,
acceleration rate, braking rate, etc.). The user can use these memory locations to quickly configure
the centrifuge for a specific test type and ensure that the test is run in the same way each time by
recalling this same setting.
Store a configuration in a memory location
1. Adjust the various settings (speed, time, acceleration rate, etc.) for the
configuration to be saved.
2. Press and hold the PROGRAM button until the preset display begins to flash.
3. Press the MEMORY button to increment the memory location by one. Continue
to press the memory button until the desired location is displayed.
4. Press the program button to store the current configuration into the memory
location that is displayed.
Recall a configuration from a memory location
1. Press the MEMORY button until the desired memory location is displayed in the
memory display.
2. As you review the presets, the settings on the control panel will change to
reflect the settings stored in the memory preset currently displayed.
3. When the desired preset is found, pause and the memory display will
momentarily flash. The stored configuration is now loaded.
Notes:
Once a configuration has been loaded, it will remain active until any change is made on the control
panel. If for instance the user adjusts the time, the current configuration will no longer match the
previously loaded configuration and the memory display will change to a “-” dash. The previous
configuration may be recalled using the procedure described above.
Memory locations my be overwritten by selecting them during the store procedure.
DIGITAL CYCLE COUNTER:
This centrifuge is equipped with a digital cycle counter to monitor machine usage and for routine
maintenance.
To display the current cycle count, perform the following:
1. Unlock the lid by pressing the OPEN/STOP button.
2. Open the lid latch so that the yellow LOCKED indicator light is not illuminated.
3. Press and hold the START button for approximately five seconds. The word
“CYCLES” will be displayed in the speed display and the current cycle count will
be displayed in the time display. If the current cycle count exceeds 9,999
cycles, the cycle count will be displayed by showing the first part of the number
and then the end of the number. For example: the 1st shown is 0002 and the
2nd shown is 4537 represents 24,537 cycles.
