Operation
The unit is ready for your immediate use. All control parameters, calibration and tuning has been preset. No adjustments are
necessary.
To turn on the incubator, switch the power switch located on the rear, to the ON position. Allow the incubator to reach the set
temperature and stabilize. The unit is ready for use. Operation and use of the incubator is relatively simple. Simply set your
desired temperature and allow the unit to stabilize. The incubator shelves are adjustable. The shelves may be placed on any
of the shelf pins to accommodate your samples. You may also choose to use only one shelf or no shelves if needed. If you
are running single or small samples, it is recommended that you place a shelf in the center of the incubator and use it for your
samples. The incubator temperature sensor is located in the center of the unit and this will provide the most even
temperatures.
The incubator should be placed several inches away from any wall or other equipment for proper ventilation.
Using the PID Temperature Controller
This incubator has been calibrated for accuracy and the unit has been shipped from LW Scientific set to 100 degrees
Fahrenheit. The PID Temperature controller will be illuminated when the power is turned on to the incubator. Once turned on,
the PID will show the actual temperature of the interior of the incubator, and the temperature will gradually increase until it
reaches the SET temperature. The incubator should reach 100 degrees within 30 minutes, depending on ambient/initial
temperature. It will possibly over-shoot the set temperature slightly, but will settle onto the correct temperature within a few
minutes. It is best to turn your incubator on at least 30 minutes prior to use.
LW Scientific has preset all programming functions of the PID controller as it shipped from the factory in Atlanta. There are
many complicated programming functions built into the PID controller, which should not be altered by the customer. The only
3 functions that may need to be altered by the customer are “Set Temperature”, “Change from F to C”, and “Temperature
Offset”.
Change Set Temperature
Press ^ or V once to display Set Temperature. The display will blink.
Press ^ or V again to increase or decrease the Set Temperature value.
Wait 8 seconds and the new Set Temperature value will take effect and stop blinking.
Change from Fahrenheit to Celsius
If the units need to be changed to Celsius, access the PROGRAM MODE on the PID controller as shown in the flow chart below.
Press SET
Enter code 0089 and press SET
Press the V until “CorF” shows
Press SET and use the ^ button to choose “O” for Celsius
Press SET, and then the ^ button until you see “END”
Press SET to exit
Change Temperature Offset
The temperature offset will not normally need adjustment; however, if the incubator ever needs an offset to correct for
differences between DISPLAYED TEMP and ACTUAL TEMP inside the chamber, the PID controller can compensate for that. If
the offset needs to be changed, access the PROGRAM MODE on the PID controller as shown in the flow chart below.
Press SET
Enter code 0089 and press SET
Press the down arrow until “PSb” shows
Press SET and enter the offset value (for example enter “1” to offset by 1 degree)
*For negative values, shift to the very left digit, press down key until “-“ shows
Press SET, and then the ^ button until you see “END”
Press SET to exit
If any other parameters need to be altered, please call the LW Scientific technical support team at 800-726-7345 before
making changes.
