2.1 Operation Instruction

The Incubating Orbital Shaker has been designed for the temperature, speed and time functions to work
independently of one another. The temperature and speed can be reset without resetting the timer and the
timer can be stopped and started without interrupting the heating and shaking functions.
1.
Getting ready:
a) Plug the power cord into a properly grounded 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 temperature, speed and time displays will illuminate, displaying the previously used
settings.
NOTE: ISHD23CDG units have a toggle switch on the left side. This switch must be in the "on"
position (depress "I") for the unit to function properly.
2.
Setting temperature:
a) Press the up/down arrows below the temperature display until you reach the desired temperature.
When you release the button, the display will blink off and then on indicating the new set temperature
has been accepted.
b) Press the on/off button to start the heating function. The indicator light below the temperature
display will illuminate to indicate the heating function is in use and remain lit until heating has
ceased.
c) Temperature adjustments can be made without interrupting heating by using the up/down arrows
below the temperature display. After the change has been made and you release the button, the
display will blink off and then on indicating the new set temperature has been accepted.
d) To stop the heating function, press the on/off button below the temperature display. The heat
indicator light will turn off.
CAUTION HOT indicator:
The caution hot indicator light warns that the temperature of the air in the chamber is above
40°C (104°F). The light will illuminate and remain lit when the temperature of the air in the
chamber reaches approximately 40°C (104°F). When the heat is turned off, the caution hot
indicator light will stay lit until the temperature of the air in the chamber is less than 40°C
(104°F).
3.
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 and blink until the set-point is reached. Once the set-point is reached the light will stop
blinking 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.
To stop the shaking function, press the on/off button below the speed display. The speed indicator
d)
light will turn off.
4. 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.
