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.

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.

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.

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 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:
