Chapter 1: Introduction

This manual will guide you through the process of validating the DatPass and MicroLab
software package to GMP 4 and FDA Title 21 CFR Part 11 guidelines. This manual will
provide users with a test plan for their own performance and operational qualification of
DatPass and MicroLab, together with the MicroLite data logger.
This document is comprised of the following main sections:

• Overview of FDA Title 21 CFR Part 11 and the implementation of these sections in
the Omega software package.

• Necessary validation test sheets for DatPass and MicroLab.

• User guide for using the DatPass software.

• User guide for using the MicroLite data logger.

• User guide for using the MicroLab software.

It is important to understand that the implementation of the CFR guidelines is not the
sole responsibility of Omega Engineering. The software user must undertake a large
portion of the responsibility through the appropriate validation tests.

The software package consists of two programs:

• DatPass –MicroLab administration application

• MicroLab – Data acquisition and analysis application

To validate the software package, start by testing DatPass, followed by MicroLab.
Some of these tests assume that the user is familiar with the Windows interface in
addition to the DatPass and MicroLab software.

Chapter 2: What is Title 21 CFR Part 11?

The Food and Drug Administration (FDA) issued the regulations Title 21 Code of Federal
Regulations Part 11. These regulations provide criteria for acceptance by FDA, under certain

circumstances, of electronic records, electronic signatures, and handwritten signatures executed
to electronic records as equivalent to paper records and handwritten signatures executed on
paper. The regulations apply to all FDA program areas, and are intended to permit the widest
possible use of electronic technology, compatible with FDA’s responsibility to promote and protect
public health. Part 11 applies to any record governed by an existing FDA predicate rule that is
created, modified, maintained, archived, retrieved, or transmitted using computers and/or saved
on durable storage media.

Title 21 CFR Part 11 Definitions

Electronic Record

Any combination of text, graphics, data, audio, pictorial or other information representation in
digital form, that is created, modified, maintained, archived, retrieved or distributed by a computer
system.

Electronic Signature

A computer data compilation of any symbol or series of symbols, executed, adopted or authorized
by an individual to be the legally binding equivalent of the individual’s handwritten signature.

Digital Signature

An electronic signature based upon cryptographic methods of originator authentication, computed
by using a set of rules and a set of parameters such that the identity of the signer and the integrity
of the data can be verified.

Closed System

An environment in which system access is controlled by persons who are responsible for the
content of electronic records that is on the system.

Open System

An environment in which system access is not controlled by persons who are responsible for the
content of electronic records that is on the system.

Standard Operating Procedures (SOPs)

Guidelines and rules defined by the organization implementing Title 21 CFR Part 11 compliance
to instruct users what they are and are not permitted to do and how they are to perform the
relevant tasks.

Omega's Software

The dual program software package achieves compliance with FDA Title 21 CFR Part 11 with:
MicroLab and DatPass. The DatPass software is the administration software, which includes
features that define the users that can log into the MicroLab software, their passwords and the
digital signatures the users are permitted to sign data within electronic records (files). The
MicroLab software is used to access the electronic records, display the logger data, analyze the
data and allow the user to add the appropriate digital signatures to the electronic records, in
addition to other features. An additional security feature is the USB port dongle, without which the
MicroLab and DatPass software packages will not operate.

Chapter 6: MicroLite User Guide

Introduction

The MicroLite is a compact 16-bit USB data logger designed for accurate temperature
monitoring for a wide range of applications. Due to its low cost, the MicroLite can be
used as a One Trip Logger, for monitoring temperature of perishable goods during
transportation, for example. Other typical applications include warehousing of food,
monitoring of controlled environments i.e. in the pharmaceutical industry, and many
more.

Using the MicroLite

The MicroLite can be used as a standalone device to monitor
temperature levels. The MicroLite LCD screen continuously
displays the current temperature recordings and the maximum
and minimum temperature readings. You can also define
minimum and maximum alarm levels for a specific data logging
session, and the LCD screen will also show any alarm levels that
may have been breached as well as the duration of the alarm.
The data stored by MicroLite can be easily downloaded to any
computer for further viewing and analysis using the MicroLab
software, and can also be exported to an Excel spreadsheet.

Getting Started

The MicroLite data logger you have purchased is shipped in a plastic box with a Quick
Start Guide printed on the rear of the box.
The box contains one MicroLite data logger and one small magnet accessory (located in
the placeholder on the MicroLite packaging). Read more about the purpose of this
magnet on page 34.

In order to save battery life, MicroLite is shipped in Stop Mode. This means that before
you can start recording, you must first connect MicroLite to the PC and set it up with the
MicroLab software.
Refer to Chapter 8: MicroLab User Guide to learn how to run the MicroLite from the
software, including how to set up the logger. Once MicroLite receives the Setup
command from the software, it begins logging the temperature data immediately or waits
for a predefined time to start logging.

Reading the MicroLite Display

The MicroLite has a 3-digit (with one decimal place) 7-segment LCD screen, which is
able to display the following information:

• The temperature reading currently recorded

• The lowest and highest temperature recorded to that point

• Low and/or high alarm level breach

• Duration of low and/or high alarm level breach

• Low battery warning

- 30 -

Data Displays

The LCD displays the data in a continuous cycle, alternating in duration according to the
order shown in the table below:

Time on

Screen

(seconds)

8 Temperature (in Celsius

2 Low alarm duration *

2 High alarm duration *

2 Minimum temperature

Current Temperature Reading

This is the last temperature reading recorded by the MicroLite. If the sampling interval is
once per second, then the reading will be updated for each of the four seconds it
displayed on the LCD. Therefore you will be looking at the actual temperature recorded
at that very moment.

MicroLite Alarm

MicroLite displays an alarm notification whenever any alarm level is exceeded.

AL-L – The temperature reading is lower than its low alarm level (as defined in the logger

Setup).

AL-H – The temperature reading is higher than its high alarm level (as defined in the

logger Setup).
The alarm notification remains until the next time you download data to a PC.

The alarm duration on the logger’s LCD is calculated in hours. For example, the shortest
possible duration of 0.01 hours means the logger has been in alarm for between 0 and
36 seconds.
A duration of 1.55 hours means the logger has been in alarm for 93 minutes.
If the MicroLite is in a Low and High alarm simultaneously, then it will show the duration
for both alarms.

Note: When the MicroLite is in Cyclic mode, the Low or High alarm level displayed
represents the lowest or highest readings recorded since the MicroLite starting logging
data, irrelevant of how many cycles the logger has recorded.

Minimum and Maximum Temperature Readings

The logger display automatically scrolls through the Min/Max temperature readings while
sampling.

- 31 -

These readings are simply the minimum and maximum temperature values recorded by
the MicroLite up until that point. If your logger has breached an alarm level, look at the
MIN and MAX readings to see the extent of the low or high alarm level breach.
These readings are constantly updated.

MicroLite Working Modes

MicroLite is always set in one of five possible modes. These modes are all activated via
the MicroLab software.

Stop

MicroLite is idle and is not recording.
When pressing Stop in the MicroLab software, the logger LCD immediately ceases to
record data, instead displaying STOP and scrolling through the alarm durations (if
alarms were previously recorded).

Run

MicroLite is recording data. It will stop recording automatically when its memory has
reached full capacity (8,000 or 16,000 samples depending on the model).

Cyclic Run

Similar to Run mode, but MicroLite will continuously sample data, recording over old
data when the memory reaches its capacity, beginning with the earliest data recording.

Timer Run

MicroLite can be configured to start recording at a predetermined time. When MicroLite
is set for such a run, its status is set to Timer Run. The logger LCD displays tRUN.

Push to Run

MicroLite will only begin logging data when the user operates the logger’s reed switch
with the MicroLite magnet. The logger LCD displays PUSH.

USB Port Connection

The MicroLite interfaces with the computer via any of its USB Host ports. In order to be
detected by the computer and by the MicroLab software, the USB driver must first be
installed. USB driver installation is part of the software installation.

MicroLite LCD Status when Connected to USB

The USB connection status is always displayed on the MicroLite LCD when connected
or disconnected from a USB port.
The LCD flashes USB ON once when connected and flashes USB OFF once when
disconnected from the USB port.
The logger LED (located adjacent to the logger’s USB connector) also lights up green
when connected to the USB port.

If the MicroLite is in Run mode when connected to the USB port, the LCD will only
display the current temperature reading and will not scroll through the other readings.

- 32 -

If the MicroLite is in Stop mode when connected to the USB port, the LCD will display
STOP. If the logger had recorded an alarm during the previous data logging session,
then the LCD will also scroll through the alarm durations.

The MicroLite Battery

The MicroLite runs on a standard 3V CR2032 lithium battery.
The battery maintains the MicroLite’s Real-Time Clock (RTC). The logger’s time/date
settings are synchronized with the PC when you perform a Setup. Removing the battery
will return the logger’s time/date settings to the default of 01 Jan 2004.

Battery Level

The MicroLite battery level indication is provided in the MicroLab software’s Setup
dialog.
The MicroLite battery’s maximum lifespan is approximately two years. This long battery
life is achieved by the MicroLite putting itself to sleep between data recordings. While in
sleep mode, the data logger consumes a minimal amount of power.
MicroLite wakes up for a few micro-seconds whenever it has to record a data sample or
display new data on the LCD screen.

Moving the Current Database

The Current.mdb file is by default located in the DatPass directory on your local
computer. This file contains the current audit trail of user activity in DatPass and
MicroLab.

When the Current database is located locally, it only tracks user activity on your
computer. In order to maintain an audit trail of user activity over a network, rather than
locally, you must store the DatPass Current.mdb file in a directory on the main network
server to which the MicroLab users are connected.

To move the database file in DatPass:

1. Click Move Database on the File menu.

- 45 -

2. In the Set Database Path dialog box, click Browse and browse to the new
location of the database file.

3. Ensure that all MicroLab software is closed and exit DatPass, then re-enter
DatPass.

4. You should receive a system message confirming the database move, and you
should also be able to view the action in the Audit Trail.

Note: You will only be able to move the database if you have the Group privilege to do
so. The Move Database check box must be checked in the Group Properties dialog
box.

When the Current.mdb file has been moved using DatPass, the database path must also
be updated for all MicroLab software users on the network.

To correct the database file path in MicroLab:

1. When logging into the software for the first time following a database move, you
will see a system message stating that the database file was not found.

In the next dialog box, enter the default system password (refer to the

Move Database Password section below) and click Browse.

2. Browse to the new path of the database file, as defined in DatPass, and click OK.

3. Login in to the software as you normally would.

The DatPass Admin will now be able to view the audit trail of all users of the MicroLab
software on the network.

Move Database Password

The default password allowing users of MicroLab to correct the database file path once it
has been moved is:

omega

This password is case sensitive and cannot be changed.

Viewing more than one Data Set on the Graph

MicroLab lets you view more than one data set in Graph and Table view at the same
time, allowing you to compare the data from several data sets side by side.

Note: To use this feature the data sets must have been recorded using the same
sampling rate e.g. every 1 minute

There are two modes when using the Multi-graph feature:

Standard mode

The time scale of all data on the graph is the same. The time and date of data recorded
in the first data set included on the graph is used.
For example, if you have a graph whose data was recorded starting 10:00AM on August
11, then all additional data added to the graph will be displayed with the same recording
date.

The MicroLab data table below shows all data in the graph having the same time scale:

Figure 6: MicroLite data table

Plot sync mode

To display data on the graph using the data’s actual time scale i.e. the time and date
when the data was actually recorded, use the Plot sync feature. This will also shift all
data in the data table accordingly.
Once you’ve added the data to the graph, on the Graph menu, select Plot sync to
enable the feature. To return to Standard mode, unselect Plot sync.

Note: The time scale of all data is rounded to the same resolution as the time scale of
the original data on the graph.

Analysis Tools

Setting the Analysis Tools Parameters

1. Click Analysis on the menu bar, then click Set Functions’ Parameters to open a
dialog box:

- 59 -

Figure 7: Functions Parameters

2. Type in the desired parameters, and then click OK.

Histogram

Use this tool to create a frequency distribution of the selected data set.
To create a histogram:

1. Use the cursor to select a plot on the graph.

2. Click Analysis on the main menu bar, then click Histogram.

MicroLab displays a histogram of the selected data and creates a new entry in the Data
Map.
Use the Data Map (refer to page 55) to hide the histogram or to return to the original
data sets.

You can modify the histogram to your needs. You can set the upper limits of the first bin
and the lower limit of the last bins, and refine the histogram by increasing the number of
bins.

To modify the histogram:

1. Click Analysis on the main menu, then click Histogram a second time to open a
dialog:

Figure 8: Histogram settings

2. Enter the desired values for the first bin, the bin width and last bin, and then click
OK.

You can repeat the process for further modification.

Use the statistics tool to display statistics of each data set in the graph.
The statistics include:

Minimum – The smallest value in the data set.
Maximum – The largest value in the data set.
Average – The average of all the numbers in the data set.
MKT – The Mean Kinetic Temperature.

To display statistics:

Click Statistics

MicroLab will display the statistics in the information bar at the bottom of the graph
window.
