Orbital Shaker
1. Place a 250ml Erlenmeyer flash (filled with approximately 100ml of
liquid) in approximately the geometric center of the platform.
2. Suspend an independent temperature measuring device of known
accuracy into the flask. The sensor should be submerged in the liquid
but not in contact with the bottom or sides of the flask.
3. Adjust the shaker temp setpoint at desired calibration temperature.
4. Set the shaking speed setpoint to 75 RPM.
5. Start the unit and allow a minimum of 2 hours stabilization of cabinet
and flask liquid.
6. Enter Calibration mode by pressing
the down arrow, the up arrow, the
Silence button. Then press the down
arrow twice. The screen at right will
appear on the display:
7. Press the Temperature button
beneath Temp.
8. Using the up and down
arrows, increase or decrease the
temperature value to match
the independent, accurate
temperature measuring device.
9. When complete, press the Time, Speed, or Temp button to save the
setting. The display will return to the Calibrate - RPM Temp screen.
(Or, if nothing is pressed for about fifteen seconds, the display will
return to the Operating Screen and the setting will be automatically
saved to memory.)
10. Allow the cabinet to re-stabilize for 1 hour. Recheck temperature. If
necessary, return to Step 6 until no additional adjustments are needed.
11. Temperature calibration is now complete. Remove calibration
equipment and resume use.
