stratus
quick start guide
Step 1: Get Started.
Conrm receipt of all components and device
(shown at left). The microSD card may already
be installed in the Stratus. Download the Cerillo Device Man-
ager onto your computer at cerillo.bio/software. Then con-
nect your device to your computer, open the Cerillo Device
Manager Software, then open the settings window to set up
your device.
Step 2: Location.
Place your Stratus where you’d like to measure.
This is anywhere your samples will be happy—incubator, an-
aerobic chamber, benchtop, hood, etc.
Step 3: Power the Device.
First, insert the microSD card. Then, plug the power adapter
into a standard wall outlet, and the USB cable into the power
adapter and the Stratus. Alterativly, you can use a computer
or battery pack to power your device.
Step 4: Allow for Equilibration.
The Stratus needs 60 minutes to equilibrate to new
environmental conditions. This can be a good time to
do your experimental prep work.
Step 5: Go!
(See reverse.)

Collected measurements are automatically stored on the on-board microSD card. You
can use any commercially available adapter to access the data from the card. When in-
serting the card into the Stratus, do so with the Stratus unplugged; otherwise, the card
will not be recognized and future data will not be recorded.
Data les are stored in order of when your experiment took place (in “YYYYMMDD”
format). Inside each day’s folder are data les titled by the time the experiment was
started (in “hh-mm-ss” format). These are saved as standard .csv les, and can be
opened in any spreadsheet or data analysis software. The Stratus’ internal clock is
already set to your time zone by Cerillo at the time of shipment.
The Stratus can be operated by plugging the provided USB cable into a computer’s
USB port instead of the power adapter. If you would additionally like to control the
Stratus and read its data from that computer, you can download Cerillo software at
cerillo.bio/software. This software enables direct control, data access, and congura-
tion of the Stratus.

1. The Stratus needs calibration after equilibrating to a new environment. Hold down
the Stop (right) button until the status light ashes. Then release it. When the status
light turns off, calibration is nished. The calibration process takes about 3 minutes; do
not press any buttons during calibration.
2. Insert the plate, then press and release the Start (left) button on the Stratus to read
your plate once.
Press the Start button and hold until the status light begins to ash white. After a 10
second delay the Stratus will auto-calibrate and then begin to continuously read. To
stop a reading in progress, press the Stop (right) button until the status light turns red.
