Introduction

LogTag’s USRID-16W models are pre-configured, single use USB PDF temperature
indicators with a data logging function.They feature a display, which allows select
statistical data to be reviewed directly on the unit without the need for a PC. Trip reports
can be generated without the need to install proprietary software or hardware at the
destination.

Each model is pre-configured to the requirements of the WHO PQS Shipping Indicator
specification (while still allowing limited configuration using LogTag® Analyzer) ready to
be started and placed with the goods to be monitored . At the destination the USRID-16W
can be plugged straight into a computer’s USB port and generates a PDF file, which can be
accessed using PDF software such as Acrobat Reader. For further analysis, data can be
downloaded using the free companion software LogTag® Analyzer, where you can display
data in chart, list or summary formats.

Alarms

Configuring alarms for WHO PQS qualified USRID-16W1 and USRID-16W2 models is not
permitted. The alarm trigger requirements are set out in the WHO/PQS/E006/TR07 PQS
performance specification for Electronic Shipping Indicators. Each indicator is configured
with 3 different alarm trigger conditions for temperature.
Alarm trigger conditions consist of a threshold temperature value, an activation type
(which can be instant, consecutive or accumulative) and a delay time. If an alarm trigger
condition requires readings to exceed an upper threshold temperature it is called an

alarm

called a

An alarm event is generated, when at least one of the alarm conditions is triggered. The
threshold values themselves are included in the alarm range, i.e. if an upper alarm
threshold is set at +30.0 °C, a value of +30.0 °C will trigger an alarm, but a value of 29.9 °C
will not.
According to the PQS specification, alarms are triggered for different models as follows:

Pressing STOP/Review for a second time will show the
lowest recorded temperature during the trip, indicated
by TRIP MIN.

The example screen shows that the minimum
temperature recorded was -1.5 °C.

Pressing STOP/Review again will show up to three more screens, one for each of the
configured alarm trigger conditions.

A screen for a specific alarm condition will only be shown if an alarm was triggered by this
threshold. If no alarm was triggered during the trip, only the MIN and MAX screens are
shown.

The additional alarm screens will show the alarm threshold values in descending order,
starting with the upper most alarm threshold.

In this example, all three alarms triggered, so all three screens are shown.

The first of the alarm screens shows the uppermost
alarm threshold, and the time that elapsed between the
start of the trip and the time the alarm was triggered.

In the example, the temperatures were equal/above +45
°C for one complete hour, and the alarm was triggered 17
days and 6 hours into the trip.



The second alarm screen shows the next threshold. In
the example, the temperatures were equal/above +30 °C
for a total of 10 hours, and the alarm was triggered 16
days and 21 hours into the trip.



The third alarm screen shows the lowest threshold. In
the example, the temperatures were equal/below -0.5 °C
for one complete hour, and the alarm was triggered 10
days and 4 hours into the trip.

Pressing STOP/Review again starts the review cycle again
with the MAX screen.

Plugging the USRID-16W into a USB port

As soon as you plug the USRID-16W into a USB port, the word USb appears.

If you have configured the logger to generate files, USb remains turned on until all files
have been generated.

Find Quality Products Online at: [e-mail]

www.GlobalTestSupply.com

Operating the Logger USRID-16W User Guide 21

As soon as the file generation is finished, USb will blink every second to indicate these files
can now be accessed.

The files are generated each time you plug the logger into the USB port, regardless
of whether the logger is still recording readings or not.



What happens on your computer depends on the operating system of the computer, the
settings made during configuration and whether or not LogTag® Analyzer is running.

Microsoft Windows

Up to four drivers will now be installed, depending on the USRID-16W's configuration.

All drivers are part of the operating system and will typically not require administrator
privileges for your computer.

1. Mass Storage Device

2. LogTag Mass Storage USB Device

These two devices are required so you can access the data files in the same way as a
USB memory stick. These drivers will not be installed if the USRID-16W does not
generate files.

3. USB Input Device (HID)

This device is used for communication to LogTag® Analyzer and its driver will always
be installed, even if LogTag® Analyzer is not present on the computer.

4. USB Composite Device

macOS and Linux

Typically, in these operating systems a new drive will be mounted, from which you can
open the PDF file. You will not be able to configure the USRID-16W using either of these
operating systems, unless you use virtualization software such as Parallels, Fusion or
VirtualBox to create a hosted Windows environment. You need to discuss these options
with your network administrator.

While a USRID-16W is plugged into USB, no temperature readings are taken. The
graph will display a gap and the data list will show --- followed by the # symbol.

Accessing the files

If the logger was configured to generate files, a new drive letter or mounted device will
appear. The device name will be created from the serial number of the USRID-16W. You
can access the files by browsing to the newly created drive and double-clicking the PDF,
CSV or LTD files.

l For PDF files you need Adobe Acrobat Reader or a similar PDF viewer.
l To open the LTD file you need to install the free LogTag® Analyzer software.
l CSV files can be opened with a text editor, or imported into a spreadsheet program

such as Microsoft® Excel.

To retain the logger-generated files, copy them to a permanent storage location
on your computer, such as the Documents folder, as they are not automatically
copied.
The data on the logger is retained. Each time you plug the USRID-16W back into
the computer the files are re-generated. Once the battery is exhausted, the real
time clock on the unit stops and dates and times for the retained data may no
longer be accurate. You will, however, still be able to access the last trip's data.

Logger Statistics Overview

This section gives a brief overview of the temperature data collected during the trip. It
shows minimum and maximum values, when these occurred and also shows average,
standard deviation and MKT values.

Recorded Data Chart

The chart shows a graphical representation of the data during the trip. As part of the
USRID-16W configuration process you set the parameters that influence how the chart is
presented.

File Information

This section shows general information about the PDF file, such as generation time, date
and time formats used in the chart and the data list as well as the file name, which is
compiled from information about the data it contains:

LogTag_[serial_number]_[trip number]_[file creation date]_file creation time]_[OK or ALM].pdf

Other files that may be generated have the extensions *.csv and *.ltd.

Logger Information and Configuration

This section shows general information such as serial number, model number, trip
number, battery status and description. It shows how the logger was started, if a start
delay was active and the interval used for taking readings.
