The Orbital/Microplate Shakers have been designed for the speed and time functions
to work independently of one another. The speed can be reset without resetting
the timer and the timer can be stopped and started without interrupting the shaking
function.
1. Getting ready:
a. Plug the power cord into a properly ground outlet. The standby indicator light
will illuminate, verifying power to the unit.
b. Press the standby button to move the unit from standby mode. The standby
indicator light will turn off and the speed and time displays will illuminate,
displaying previously used settings.
2. Setting speed:
a. Press the up/down arrows below the speed display until you reach the desired
speed. When you release the button, the display will blink off and then on
indicating the new set speed has been accepted.
b. Press the on/off button to start the shaking function. The indicator light below
the speed display will illuminate to indicate the shaking function is in use and
remain lit until shaking has ceased. The microprocessor controlled ramping feature
slowly increases speed until the set-point is reached which helps to avoid
splashing, and provides excellent low end control.
c. Speed adjustments can be made without interrupting shaking by using the up/
down arrows below the speed display. After the change has been made and
you release the button, the display will blink off and then on indicating the new
set speed has been accepted.
d. To stop the shaking function, press the on/off button below the speed display.
The speed indicator light will turn off.
3. Setting time to zero (0:00) and continuous mode: Accumulated time.
a. Press and hold the on/off button below the time display. After three (3) seconds
the display will indicate the previous set time.

b. Simultaneously press both the up and down arrows, the display will indicate
zero (0:00). The unit time is now set to zero (0:00) minutes. Alternately, you can
use the up/down arrows to get to zero (0:00).
c. Press the on/off button below the time display. The display will indicate
accumulated time. The up/down arrows will become inactive. To stop timer,
press the on/off button again. IMPORTANT: This will NOT interrupt the shaking
function. Press the on/off button below the speed display to interrupt the
shaking function.
d. To reset, press and hold the on/off button below the time display. After three (3)
seconds the display will indicate the previous set time, which was zero (0:00).
4. Setting timed mode: Programmed time.
a. Press the up/down arrows below the time display until you reach the desired
time.
b. Start this function by pressing the on/off button below the time display. The unit
will run for the selected time, the up/down arrows will become inactive while the
timer is running. The unit will stop shaking when the time display reaches zero
(0:00). Four (4) audible beeps will indicate the count down function is complete.
The time display will default back to the set time. To repeat for the same time,
simply press the on/off button again.
c. To interrupt an automatic timing cycle before it is completed, press the on/off
button below the time display. The display will flash off and on to indicate the
time function is on "hold". IMPORTANT: This will NOT interrupt the shaking
function. Press the on/off button below the speed display to interrupt the
shaking function. Restart the timer by pressing the on/off button below the
time display. Unit will continue counting down to zero (0:00). When the display
reaches zero (0:00), you will hear the four (4) audible beeps that indicate the
count down function is complete and shaking function will cease.
