5. 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 the shaking function will cease.
6. Turning unit off:
a. To turn the unit off, press the standby button. The temperature, speed and time
displays will be blank, the standby indicator light will illuminate. The Incubating
Light Duty/Microplate Shaker should be kept in standby mode when not in use.
To completely cut off power to the unit, disconnect the power cord from the unit
or unplug from the wall outlet.
OPERATING TIPS
As a safety feature, a built-in program will shut power off to the motor if the tray is
prevented from rotating, or the unit is overloaded beyond its recommended weight
capacity.
Built-in memory maintains the last used temperature, speed and time settings during
a power interruption.

SINGLE POINT CALIBRATION PROCEDURE
This procedure is used to fine tune and calibrate the Incubating Light Duty-Microplate
Shaker at a specific temperature setting. This process may be repeated for up to three
(3) separate set-points. If a fourth calibration set-point is entered, the first set-point
entered will be overwritten.
1. Turn unit on.
2. Set desired temperature.
3. Stabilize one (1) hour or more, measuring the temperature with a temperature
probe/thermometer.
4. Press and hold standby button, then press the temperature up arrow once. The
unit will beep two (2) times, confirming calibration mode. The display will now be
flashing.
5. Press the temperature up/down arrows until the display matches the temperature
probe/thermometer.
6. Press standby button to exit calibration mode and return to normal heating.
This process may be repeated at the same set-point, multiple times for fine tuning if
desired.
The unit will now use the biased offset for that specific temperature setting and
increase or decrease temperature accordingly to bring the temperature to set
temperature. The decimal point of the display will flash to indicate a biased offset is
being used. All other temperature settings will use the standard internal calibration.
This offset will be stored in memory and retained until reset.
To restore unit to factory setting:
Press and hold the standy button while pressing the temperature down arrow once.
The reset will be confirmed with two (2) audible beeps. Press the standby button to
exit calibration mode and return to normal heating.
During operation, any rattling or ticking sounds may indicate a loose screw on the tray,
a tray attachment or an accessory. All accessories should be sufficiently tightened in
place before starting the unit.
