Introduction UHADO-16 User Guide 6
Introduction
LogTag’s UHADO-16 is a fully configurable, multi-use USB PDF temperature and humidity
logger that shows the most recent reading on the built-in display and can create reports
without the need to install proprietary software or hardware at the destination. Minimum
and maximum recorded trip values can be reviewed directly on the display without the
need for a PC. The logger can be configured using LogTag® Analyzer, and is then placed
with the goods to be monitored. At the destination the UHADO-16 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. Additionally, logged data can be downloaded via a
standard LogTag® Interface to the free companion software LogTag® Analyzer, where you
can display data in chart, list or summary formats. The software also allows electronic
archiving and exporting or transmitting data in support of sophisticated data management
systems such as LogTag®Online.
Features
The UHADO-16 temperature and humidity logger features the familiar LogTag® case layout
and an additional USB socket at the bottom of the product.

logged data. In addition, a red alarm LED shows if an alarm event has occurred, and a
buzzer will sound.
Sensor
The UHADO-16 contains a digital temperature and humidity sensor. The logger comes
standard with a factory calibration certificate but can also be calibrated by third-party
laboratories for both temperature and humidity according to your needs.
PDF
The UHADO-16 will generate a detailed PDFreport when plugged into a USB port of a PC.
The PDF report shows a summary of the trip and presents the data in chart and list
format. A CSV file of the data list is also available.

Required Equipment UHADO-16 User Guide 8
Required Equipment
Aside from the LogTag® UHADO-16 USB PDF Temperature and Humidity Logger with
Display you will need the following items:
la micro-USB cable for communication to the PC (it is recommended that you connect
each UHADO-16 via a permanently plugged in micro-USB cable to protect your
computer’s USB socket, if you use the USB communication)
lone of the LogTag® USB interface models if you wish to use this method of
configuration/download
la PC running Windows 7 or later and LogTag® Analyzer installed if you wish to
configure and download the logger
la PC with PDF reader software installed for viewing the generated PDF files
Software Requirements
Software requirements vary depending on the type of file you want the UHADO-16 to
generate when plugged into a USB port.
If you wish to configure UHADO-16 products you will need to download the LogTag®
Analyzer software from LogTag®’s web site at
https://logtagrecorders.com/software/lta3/download/. Follow the instructions to install
and start the software.
If you only plan to view a report, plug the UHADO-16 into a computer’s USB port using a
micro-USB to USB-A cable. Depending on the settings made during configuration, a
number of on-board files will be generated1 and made available to you in a new drive:
la PDF file
you can open the file directly from the logger‘s USB memory storage with Acrobat
Reader 4.0 or later, or any other compatible PDF reader software of your choice2
la CSV file
this file can be imported into a spreadsheet program such as Microsoft Excel
lan LTD file
LTD files are LogTag® Analyzer's native, encrypted data files. You can open this file
in LogTag® Analyzer, where you can analyze data in detail, generate report files or
combine data from multiple recorders for comparison
You can also download data directly into LogTag® Analyzer without accessing the logger‘s
on-board files, using either a micro-USB lead or a standard LogTag® USB interface.
1 Depending on the configuration, the UHADO-16 may produce all, some or none of the files.
2 PDF files generated by any USB logger can be opened directly in LogTag® Analyzer.

Configuring the UHADO-16 UHADO-16 User Guide 9
Configuring the UHADO-16
UHADO-16 products can be ordered pre-configured, ready to start. Different profiles are
available; if none of these suit or the UHADO-16 needs different configuration settings to
those already installed, the unit can be configured using LogTag® Analyzer:
lStart the LogTag® Analyzer software.
lUsing the USB socket on the UHADO-16: Remove the protective seal and insert a
micro-USB to USB-A cable into the USB socket; connect the cable to a USB port on
your PC.
Please note the USB connector's orientation.
You will receive a message that a new USB device has been found, and a generic driver
will be installed3.
3 Depending on the factory configuration additional drivers may be installed at this time.

Configuring the UHADO-16 UHADO-16 User Guide 10
Once the driver is installed and the UHADO-16 is ready, it can receive configuration
data. Click LogTag - Configure; LogTag® Analyzer will scan all USB ports and
display the configuration options for connected UHADO-16‘s. Although you can
configure many devices at the same time, it is practical to limit the number of
devices to about 10, using a powered USB hub. It is not possible to configure different
models at the same time.
lUsing a standard USB interface: Insert the UHADO-16 into the interface, contacts
towards the rear. You can now use the UHADO-16 like any other logger with the 3
contact pins at the rear, both for configuration and for downloading data.
Standard Configuration Options
The standard configuration options are very similar to those of other LogTag® logger
products and include settings such as User ID, start method, pre-start recording,
logging interval and duration, start delay, and password.
For detailed information about each parameter please read the section about Configuring a
LogTag® for logging in LogTag® Analyzer’s User Guide or press F1 for help.
Temperature Alarm Configuration Options
LogTag® Analyzer allows up to 4 different alarm trigger conditions for temperature when
configuring a UHADO-16 for recording.
Each alarm trigger condition consists of a threshold temperature value, an activation type
(which can be instant, consecutive or accumulative4) and a delay time, if it is not an
instant alarm.
If an alarm trigger condition requires readings to exceed an upper threshold temperature it
is called an upper alarm . If an alarm trigger condition requires readings to go below lower
thresholds it is called a lower alarm .
An alarm event is generated, when either of the entered alarm conditions is triggered.
4
lInstant = one temperature reading is above (below) the threshold
lConsecutive = temperature readings are above (below) the threshold for the time defined in the activation delay without
interruption
lAccumulative = temperature readings are above (below) the threshold for the total time defined in the activation delay
time, but may not necessarily be sequential.

Configuring the UHADO-16 UHADO-16 User Guide 11
When an alarm is triggered, the display will show the alarm symbol ( ) instead of the tick
( ) and the red alert LED will blink every 8 seconds. If activated, a buzzer will also sound
(see Audible Alarm on page26). The alarms will be shown on the PDF and reported to the
software.
The UHADO-16 can have one or two upper alarms, and one or two lower alarms.
Figure 2: Alarm ranges and thresholds
Figure 3: Representation in LogTag® Analyzer
The following rules apply when entering alarm conditions into the configuration screen in
LogTag® Analyzer:
lA primary alarm condition must be entered before the corresponding secondary
alarm condition.
lYou can enter a different number of upper and lower conditions, or only upper, or
only lower conditions, or none at all.
lA secondary upper alarm cannot be entered with a lower threshold value than the
primary upper alarm. Similarly, this applies in reverse to the lower alarms.
lThreshold values can be equal and combined with different delay values. For
example, you can enter a primary upper alarm with 8°C threshold and 10
accumulative readings, plus an alarm with 8°C threshold and 5 consecutive readings.
In this instance the alarm will be triggered, if either 10 readings in total are above
8°C, or 5 consecutive readings above 8°C have occurred.

Configuring the UHADO-16 UHADO-16 User Guide 12
Humidity Alarm Configuration Options
LogTag® Analyzer allows up to 2 different alarm trigger conditions for humidity when
configuring a UHADO-16 for recording.
Each alarm trigger condition consists of a threshold humidity value, an activation type
(which can be instant, consecutive or accumulative) and a delay time, if it is not an instant
alarm.
If an alarm trigger condition requires readings to exceed an upper threshold humidity it is
called an upper alarm . If an alarm trigger condition requires readings to go below lower
thresholds it is called a lower alarm .
An alarm event is generated, when either of the entered alarm conditions is triggered.
When an alarm is triggered, the display will show the alarm symbol ( ) instead of the tick
( ) and the red alert LED will blink every 8 seconds. If activated, a buzzer will also sound
(see Audible Alarm on page26). The alarms will be shown on the PDF and reported to the
software.
The UHADO-16 can have one upper alarm, and one lower alarm.

next loggers into USB sockets, wait until they are ready for configuration and click Repeat

UHADO-16 Start Options UHADO-16 User Guide 15
Configure (or use the interface). Alternatively, you can use the Profile function to
configure multiple units with the same settings.
You can upload the configuration to a UHADO-16 logger as often as required.
UHADO-16 Start Options
During configuration with LogTag® Analyzer you can decide when the UHADO-16 starts
taking temperature readings:
Push button start
The logger will start taking temperature readings as soon as you have pressed the
START/CLEAR/STOP button).
When you choose the push button start option, you can Enable pre-start logging (or
disable it) and also Begin recording after a delay.
Pre-start readings
If you enable pre-start readings, the UHADO-16 starts recording as soon as it is unplugged
from the USB port5 and will continue to do so until you start the unit. No alarms are
processed while pre-start readings are being taken, pre-start readings will not appear in
the PDF file after the logger was started, and no PDF file will be generated if only pre-start
readings are present in the logger. Using pre-start readings is a good way to avoid data
loss if you forget to start the unit, as you can still access the data using LogTag®
Analyzer.
Start delay
If you configure the UHADO-16 to start after a delay period, the logger will not
immediately record temperature readings after you have pressed START/CLEAR/STOP, but
start a countdown timer instead, and record readings only after the timer has ended. The
value for the timer is set during configuration. If pre-start readings are enabled, these will
continue to be recorded during the delay period.
Date/Time start
The logger will start taking temperature readings at the date and time you specified during
configuration (local time). You cannot combine a date/time start with pre-start readings or
the start delay function.
5 The first pre-start reading is taken one log interval after you unplug the unit from the USB port.

Push Button Start with Start Delay
If the logger was configured for push button start with a start delay, the word DELAY is
shown instead ofthe symbol, once you have started the logger.
The delay time is shown in hours and minutes. The time counts down and the UHADO-16
starts recording when it reaches 0:00. If the start delay is longer than 199 hours 59
minutes, the clock will show 199:59 until the remaining delay is shorter than 199 hours 59
minutes.
Each time a user presses the START/CLEAR/STOP button during the start delay phase, the
start delay value is reset to its originally configured value.
Automatic date/time start
If you configured the UHADO-16 for a date/time start, it will record temperature values as
soon as the entered date and time have passed.
If the logger is still plugged into a USB port when the start time passes, the recorded
readings will show USB Paused on the PDFand in the software's reports.

Operating the Logger UHADO-16 User Guide 20
During Recording
During normal operation the display shows the most recently recorded humidity and
temperature values. The current time is also displayed in 24-hour format. A tick symbol
is shown as long as no alarm event has occurred.

Temperatures can be shown in Celsius (as on the left) or Fahrenheit (as on the right).
The temperature unit on the display is the same as used for the PDF and CSV files.
It is set during configuration.
Readings above or below alarm thresholds
If the most recently recorded humidity or temperature is above or below one of the alarm
thresholds, an alarm marker will be shown on the display.
The symbol will be shown when the most recent humidity or temperature recorded is
above the upper alarm threshold, the symbol when it is below the lower alarm
threshold.
The presence of an alarm marker on the display does NOT indicate an alarm event.
It only shows that the most recent humidity or temperature recorded was above or
below the corresponding alarm threshold value. If an alarm marker is shown, but
the display still shows a tick, a delayed alarm is configured.
In this example, the most recently recorded humidity is
above the upper alarm threshold and no alarm was
triggered:
