How to use this Guide
Using the Guide
MicroLog is a compact data logger used to monitor the temperature
and humidity of perishable goods. It can also be connected to
external sensors in order to monitor additional parameters, and can
be mounted onto a cradle for use with the Sound Alarm feature as
well as the wireless Daily Download tool.
MicroLog Plus is a sophisticated data logging system, which can
remotely monitor up to 200 MicroLogs simultaneously.
Chapter 1 of this guide details the operation procedures for
MicroLog as a stand-alone device, as well as how to work with its
software program, MicroLab.
If you are using the wireless MicroLog Plus system read Chapter 2,
which details the setup and operation of the wireless MicroLog

MicroLog
1.1. Overview
MicroLog can be used as a stand-alone device to monitor
temperature and humidity levels. All viewing, exporting and
printing of the data obtained is done with just two keys. MicroLog
continuously displays the most recent recordings, along with the
maximum and minimum values for a selected time interval. Users
can also define minimum and maximum alarm levels for a specific
shipment, and the display screen will begin to flash if either level is
breached.
(Instructions for using the Sound Alarm feature can be found in
section 3.1.1)
The data stored by MicroLog can be downloaded to any computer
for further viewing and analysis using the MicroLab software, and
can be exported to a spreadsheet.
18
MicroLog
Chapter 1
1.2. Getting Started
In order to save battery life, MicroLog is shipped in Stop Mode.
This means that before you can start recording, you must first
connect MicroLog to the PC and set it up with the accompanying
software. To set up MicroLog with the MicroLab software, refer to
section 1.4.
Once MicroLog receives the setup command, it begins logging the
data immediately.

Data Displays
1.
Current data
When MicroLog is recording, the data from the sensors is
displayed alternately. The data obtained from external sensors is
displayed with a small EXT symbol.
When MicroLog stores the data, the LCD display briefly changes
to a “double dash” (- -) symbol.
2.
Minimum and maximum values
You can display minimum and maximum values for any hour from
the last 24 hours and for any day from the last 30 days by using
MicroLog’s left and right keys:
20
MicroLog
Chapter 1
Viewing Min. and Max Values in the Last 1-24 Hours
1. Select a time period by
pressing the right key on the
MicroLog. The LCD will
begin displaying the hour
number, ranging from hours 1
MicroLog
to 24. Once you’ve reached
the desired time period, release
the right key.
2. Once you’ve released the right key, MicroLog will display the
Min and Max values logged by the sensors during the selected time
period.
3. (Optional) Once the left key is released, MicroLog will send an
IR signal of the Min and Max values for the selected time period.
21
Chapter 1
MicroLog
To receive a printout of this data, simply point the MicroLog to the
IR printer (HP portable printer – model No. 82240B).
Viewing Min. and Max Values for the last 1-30 Days
1. Select a time period by pressing the left key on the MicroLog.
The LCD will display the day number, ranging from days 1 to 30.

an IR signal of the Min and Max values for the selected time
period. To receive a printout of this data, simply point MicroLog to
the IR printer (HP portable printer – model No. 82240B).
3.
Status messages
When both the left and right keys are pressed simultaneously, the
MicroLog LCD will display MicroLog’s status. This will also
“wake up” the device, a step necessary for its communication with
a computer. The status messages include:
23
Chapter 1
MicroLog
MicroLog
– Run
– Cyclic Run
24
MicroLog
Chapter 1
– Timer Run

1.3.2.
Working Modes
MicroLog is always set in one of the 4 possible modes:
Stop – MicroLog is idle and is not recording.
25
Chapter 1
MicroLog
Run – MicroLog is recording data. It will stop recording
automatically when its memory is full (16,000 recordings).
Cyclic Run – Same as Run, but MicroLog will record over the old
data when the memory is full, beginning with the earliest data
recording.
Timer Run – MicroLog can be configured to start recording at a
predetermined time. When MicroLog is set for such a run, its status
is set to Timer Run. Once MicroLog starts recording, its status
changes to either Run or Cyclic Run, depending on the desired
configuration.
1.3.3.
MicroLog’s Connections
Note: MicroLog ships with a rubber plug that covers the rear
socket. The plug protects the socket from moisture. Unless you are
using the socket leave the plug in.
26
MicroLog
Chapter 1
1.
Connect MicroLog to a computer
For this you will need a serial communication cable (catalog
number DT058).
The serial communication cable ends
with a type D 9-pin female plug. Plug
this in to any free COM port on your
computer.
27
Chapter 1
The other end of the
serial
communication
cable ends with a small
black flat plug. Plug this
end into the socket at the
back of the MicroLog.
Note that the socket has
three pins, with one
further away from the
other two (Figure 1).
Take care to plug the
cable in correctly.

2.
Connect MicroLog to an external sensor
Use the same PC connection socket to connect to an external
sensor (see Figure 1).
Note that the socket has three pins, with one further away from the
other two (Figure 1). Take care to plug the cable in correctly.
Note: You can also connect the external sensor to the Cradle
(see page 159).
29
Chapter 1
MicroLog
1.3.4.
Sleep Mode
The MicroLog battery's maximum lifespan is approximately 1.5
years. This long battery life is achieved by MicroLog putting itself
"to sleep" between recordings, or after 4 minutes goes by without
communication with the computer. While sleeping the data logger
consumes a minimal amount of power.
MicroLog "wakes up" every second for a very short time (a few
micro-seconds) to check if one of the keys has been pressed or if
there is a message coming in from the computer. This is the reason
you have to press and hold a key for at least two seconds before a
status message appears.
If you use high sampling rates, the MicroLog battery’s lifespan will
be considerably shorter (see Figure 2).

MicroLog Plus
Overview
MicroLog plus enables wireless communication between a PC and
up to 200 MicroLog devices simultaneously. Furthermore, realtime temperature and humidity readings from the MicroLog are
automatically delivered directly to the PC. Data from external
sensors can also be transmitted in the same manner. The complete
MicroLog Plus system includes the MicroLog data logging device,
the cradle that the data logger is mounted on, a small receiver that
is placed on the PC, and the user-friendly software that allows for
convenient central management.
MicroLog Plus uses MicroLog data loggers to record temperature
and humidity readings. The cradle that the data logger is mounted
on is a wireless transmitter that can transmit measurements to a PC
from up to 300 meters. Since each cradle is tagged with an ID
number, the cradles can be programmed to transmit data at various
90
MicroLog Plus
Chapter 2
time intervals based on the criteria defined in their IDs. This
advanced feature prevents data collision between two or more
loggers.
The MicroLab Plus software reports on the status of up to 200
MicroLogs on a single color-coded interface. Other features that
help automate all aspects of the industrial data logging procedure
include the ability to store the data of each MicroLog, to set
MicroLog alarm levels and to define sampling intervals, as well as
any other necessary parameters.
The Logger menu handles all communication between the PC and
MicroLog such as programming the desired MicroLog and Cradle,
calibrating sensors, as well as defining new sensors.
The View menu controls the various data display options. Online
data can be viewed in multiple meters format (the default view), in
multiple graph format, or Cradle map format. The stored data can
be viewed on an off-line graph and table.
91

The Offline Graph menu contains all the commands needed to
format and edit the graph.
The Cradle Map menu contains all the commands needed to setup

The most common tasks and commands are available as buttons on
the Main toolbar (upper toolbar), the Graph toolbar (lower
