Introduction
Principles of Data Logging
Before working with a data logger, you need to be familiarized
with a few basic terms:
Sensor Ð A component that transforms physical data to electronic
data recorded by the OaktonLogÕs processor.
Selected Sensors Ð As a user, you can decide which of the
sensors will participate in the data recording. You select the
sensors by using the MicroLab software.
OAK ON
TempLog
Min/Max
%RH
Hour(s)
Sample Ð A single measurement taken by the data-logging
device, and stored in its memory. In this manual, we refer to a
sample as a single measurement from each of the selected
sensors.
Memory Ð The OaktonLog's memory is where the recorded data
are stored. The OaktonLog has 16,000 bytes of memory capacity
and can therefore store up to 16,000 different measurements. A
sample can take 1-3 cells of memory (depending on how many
sensors were sampled). The OaktonLog Device

The LCD display is used for viewing data without downloading
them to a PC. The left and right keys are used to view the Min
and Max values of the OaktonLogÕs measurements and to
download recorded data to a computer via a cable or the IRDA
port.
The infrared LED transmits data to a portable printer or a
computer via an IRDA port.
The external sensor/communication port is designed to connect
an external temperature sensor or a computer. The computer
connection cable and external sensor cable are sold separately in
the OaktonLog PC kit.
Battery Replacement
A 1/2AA 3.6V lithium battery powers the OaktonLog and should
last for 1.5 years. If you use an external sensor, or transmit often
via the IRDA port, this period is shortened. To replace the battery,
simply open the 4 screws in the back of the OaktonLog, replace
the battery, and reassemble the OaktonLog. Make sure that you
place the positive (+) pole towards the + sign on the OaktonLog
circuit board.
NOTE: BEFORE REPLACING BATTERIES,
MAKE SURE YOUR HANDS ARE CLEAN AND DRY.
OaktonLog Factory Settings
The OaktonLog is initially configured to work in a Cyclic Run
mode, taking a sample every 6 minutes from each sensor. The
Cyclic Run mode means that the OaktonLog continuously
records data until its memory is full, and to overwriting then the
oldest samples. To change the initial configuration you have to
use the MicroLab software (see page 3).
The OaktonLogÕs Buttons
The OaktonLog device has 2 keys used to display and transmit its
data and status. The following pages deal with the functions of
these 2 keys:
Viewing Min/Max Values in the Last 1 to 24 Hours
You can view the minimum and maximum values measured
during a specific time period up to 24 hours by using the
OaktonLog's right key. To view those values, you need to perform
the following 3 steps:

%RH
1. Select a time period Ð when you press OaktonLogÕs right
button, the LCD will start displaying the number of hours.
When you reach the desired time period (ranging from 1 to 24
hours), release the right key.
2. After releasing the right key, the OaktonLog will display the
Min and Max values of the selected sensors, for the selected
time period.
3. (Optional) After releasing the right key, the OaktonLog will
send an IR signal of the Min and Max values for the time
period selected in step 1. To receive a printout for these data,
point the OaktonLog to the IR printer (HP portable printer Ð
model No. 82240B).
NOTE: You cannot enter a time period greater than the time
elapsed since entering Run mode.
Viewing Min/Max Values in the last 1 to 30 Days
You can view the minimum and maximum values measured
during a specific time period up to 30 days by using the
OaktonLog's right key. To view those values, you need to perform
the following 3 steps:
1. Select a time period Ð When you press the OaktonLogÕs left
key, the LCD will start displaying the number of days. When
you reach the desired time period (ranging from 1 to 30 days)
release the left key.
2. After releasing the left key, the OaktonLog will display the Min
and Max values of the selected sensors, for the selected time
period.
3. (Optional) After releasing the left key, the OaktonLog will send
an IR signal of the Min and Max values for the time period you
selected in step 1. To receive a printout for these data, point
the OaktonLog to the IR printer (HP portable printer Ð model
No. 82240B).
You can also find a scheme of this procedure on your minimanual reference card.
NOTE: You cannot enter a time period greater than the time
elapsed since entering Run mode.
Viewing the OaktonLogÕs Status
The OaktonLog is always in one of the 4 possible modes:

The LCD displays
the current status of
the OaktonLog
Run Ð The OaktonLog is recording data. It will stop recording
when the memory is full.
Cyclic Run Ð Same as Run, but the OaktonLog overwrites the
old measurements (starting with the oldest one) when the
memory is full.
Timer Run Ð You can configure the OaktonLog to start recording
at a predetermined time. When the OaktonLog is set for such a
delayed run, the OaktonLogÕs status will is set to Timer Run.
Once the OaktonLog starts recording, the status changes to either
Run or Cyclic Run, depending on your configuration. The
following diagram indicates how to view the status of the
OaktonLog:
When you press both keys simultaneously, the OaktonLogÕs LCD
will display the status of the OaktonLog. It will also Òwake upÓ the
OaktonLog device for communication with a computer.
Downloading Data to a computer via IRDA Port
The OaktonLog is equipped with an infrared transmitter. Using the
OaktonLogÕs keys you can transmit the data stored in the
OaktonLogÕs memory to your computerÕs IRDA port. To perform
this function you need to perform the following 4 steps:
1. Open the MicroLab software on your computer.
2. Point the OaktonLog towards the computerÕs IRDA port.
3. Hold both keys down for 2 seconds. The OaktonLogÕs LCD
will change to PC.
4. The OaktonLog downloads all the data to the computer and
displays a graph of them.
The following scheme shows how to download the data:
The MicroLab Software
