Introduction
Datapaq
®Tracker systems, incorporating Insight™ software, are complete
systems for monitoring and analyzing the temperature profiles of products
within your heat-treatment process; accurate data acquisition and powerful
analysis techniques are combined with flexibility and ease of use. The Tracker
system’s power and flexibility make it a perfect tool for process-temperature
monitoring, from commissioning and troubleshooting to process optimization,
ensuring consistent quality of product and maximum efficiency.
Current temperature characteristics can quickly be compared with previously-
stored reference curves to detect operating abnormalities – and innovative
analysis techniques help in identifying problems, fine-tuning the process and
reducing running costs.
A powerful and flexible printing option allows the user to generate and
customize reports, including any or all of the analysis results or raw
temperature data.
The basic Tracker system hardware comprises:
•Data logger (including communications lead and charger) (p. 11).
•Thermal barrier and thermocouple probes (not covered here; see the
relevant manual supplied with your system).
•Hardwired telemetry (p. 55) as standard, and an optional TM21 radio-
telemetry system (described in its own User Manual).
This manual is for Tracker systems supplied with a Datapaq TP3 data logger,
and focuses on all aspects of using that logger. There is also guidance on setting
up the Insight software; complete information on using the software is con-
tained in the online Help system available after it is installed. For information on
choosing and using the logger’s thermal protection (barriers and heatsinks) and
thermocouple probes, as well as step-by-step instruction on how to collect
temperature-profile data on a product as it runs through your process, see the
relevant manual supplied with your system.
This manual, and other Datapaq user documentation, in various languages, is
available on the Insight installation DVD included with Datapaq systems. During the
software installation (p. 37), you may select documents to be copied to your PC
for rapid on-demand viewing through Insight.

10 Introduction DATAPAQ TP3

DATAPAQ TP3 Specifications and Operation 11
Logger Specifications and
Operation
The TP3 data logger is at home in a wide range of heat-treatment applications.
Its capacity for recording over 3.6 million data-points makes it a supremely
powerful, accurate and in-depth data-collection tool; combined with a built-in
transmitter to see temperature profiles developing in real time, this is an ideal
data logger for all applications.
The logger’s key features are:
•Two model sizes to suit different applications.
•Huge memory capacity for detailed process analysis: a total of over
3.6 million data-points (p. 13).

12 Specifications and Operation DATAPAQ TP3
•Ten or 20 thermocouple channels (depending on model size; see below)
for maximum data collection on each run.
•Can be specified for use with various thermocouple types (B, J, K, N, R,
S, T; see p. 14) and with analog inputs (current and/or voltage; see
p. 29) – or with a mixture of thermocouple types and/or analog inputs.
•Powered by standard alkaline AA batteries or by user-replaceable
rechargeable NiMH batteries; for high-temperature applications
involving logger operating temperatures (i.e. inside the thermal barrier) of up
to 110°C/230°F, can also be powered by non-rechargeable lithium
batteries. Any logger can use any battery-type interchangeably if
appropriate battery housings are used (available separately). See p. 17.
•Short sample intervals, to collect maximum data in minimum time
(p. 13).
•High accuracy for compliance to tight specifications (see p. 14):
for type K thermocouples, ±0.3°C/0.5°F (above −100°C/−148°F);
for type N thermocouples, ±0.4°C/0.7°F (above 0°C/32°F).
•Data gathered by the logger but not yet downloaded (‘hot data’) is
protected by non-volatile memory or by software warning if reset is
attempted before download.
•USB and Bluetooth communication (p. 29).
•Hardwired telemetry (p. 55) or (if specified for use with optional
TM21 system) radio telemetry for monitoring in real time – both with full
analysis functions and alarms to warn the user if the process is out of
specification.
•Four LEDs to show the exact status of the logger’s activity and its batteries
(p. 15).
•Start and stop buttons for easy user control (p. 17, p. 53).
•Rugged case and electronics allow operation in harsh environments of
dust, pressure and vacuum.
•Reset possible by start button alone, for speed and simplicity (p. 47).

run mode and 10 runs have been
performed (p. 45), logger powers
up (but will not start a new run or
delete data). If in multiple-run mode
and fewer than 10 runs have been
performed, logger starts logging.
Each run of a multiple run will
be performed using the same
data-collection options, until the
logger is reset.
Press RED button. Stops logging. Data retained in memory. Logger
cannot be restarted until data is
downloaded (unless in multiple-
run mode, p. 45). Red LED
flashes every 5 seconds to warn
of data in memory. If in telemetry
mode, will also send ‘end of run’
signal to end real-time run.
Press GREEN and
RED buttons together
and hold for 5 seconds.
Turns logger off. All four LEDs
flash together, once.
Data retained in memory. The
previous reset options are
retained as current default.
It is possible to set the logger up so that use of the stop button is disabled during
a profile run. See p. 53.
Battery
Every TP3 logger can use three battery types interchangeably.
•NiMH rechargeable (see p. 21).
•Alkaline AA (see p. 23).
•Lithium non-rechargeable for high-temperature use (see p. 25).
Each type uses a different battery housing, identified by a different-colored label
(see below) which also shows the logger’s permitted operational temperature.
All types can be replaced by the user.

Interchangeable battery-packs and housings:
NiMH rechargeable (left, p. 21), alkaline (center, p. 23)and lithium (right, p. 25).
The logger automatically detects the type of battery in use, which prevents
damage to non-rechargeable batteries if the charger is connected by mistake.
To remove the battery housing from the logger (in order to replace with a
new one or to change the battery type in use), see p. 23.
For disposal of batteries, see p. 34.
When the communications lead is attached, the logger is powered via USB.
Batteries can be left in the logger, but they are not then required (except when the
logger is being reset for a non-telemetry run; see p. 41).

DATAPAQ TP3 Specifications and Operation 19
Battery Life
For a given battery type, battery life is affected by the following factors.
•Operating Temperature – Essentially, the higher the ambient
temperature the battery operates in, the shorter will be the life. Batteries
that operate for a large part of the process cycle at relatively low
temperatures will have a longer life than those that operate for the majority
of the process cycle at the maximum operating temperature.
•Sample Interval – The shorter the sample interval, the shorter will be the
battery life. This is because power is being consumed each time the logger
takes a reading. A short sample interval will achieve the maximum amount of
information, but this must be balanced against the greater battery charge
required.
•Bluetooth – Bluetooth communication causes extra battery drain, and
should be turned off (see p. 31) if not used.
•Operating with Radio Telemetry – Sending data to a receiver outside
the oven, furnace or kiln requires more power than that needed simply to
read and store the data.
Given the factors that can affect the life of a battery it is obviously difficult to
predict accurately. The LEDs on the logger will give the best indication of when
the battery is low. In the user’s own conditions, experience will quickly indicate
typical battery life, and a log should be kept for the first few runs, noting sample
interval and whether radio telemetry was used.
See the sections below on specific battery types for guideline battery-life data.
The Logger Reset dialog (p. 42) shows actual battery use: the time since
the battery was last charged or last changed.
Charge Level of Batteries
When the battery’s charge drops to 20% of the full level, this will be shown by
the logger LEDs (p. 15).
For NiMH and alkaline batteries only... When connected to the PC, the
Insight software shows the logger’s battery-charge level as a percentage of full
charge, as follows:
•In the main Logger Reset dialog (p. 41).
•When using wizards which reset the logger.
•During communications setup (p. 40).
•When using the Real Time Tool dialog during Bluetooth telemetry (p. 32)
or during use of the optional TM21 radio-telemetry system.

20 Specifications and Operation DATAPAQ TP3
For alkaline batteries, the battery-charge level displayed by Insight will be valid
only if Duracell or other quality batteries are fitted. Using inferior batteries may
cause misleading percentages to be shown.
Battery Voltage
The logger records the battery voltage during a profile run. This is then
downloaded to be stored in the paqfile and can be displayed on screen alongside
the temperature profile. See p. 53.
Auto Power-off
To save battery life, the logger will power-off automatically in the following
situations.
•The communications lead is unplugged when the logger does not contain
data which has not been downloaded (e.g. after a data-download) and the
logger has not been reset.
•The PC is powered down while the logger is connected to it.
•The logger contains data from a previous run which has not been
downloaded (the logger-status red LED will be flashing every 5 seconds), and
has been in this state for 5 minutes (or for 30 mins if Bluetooth is turned on;
see p. 29). Note that:
○The power-off will not cause this data to be lost.
○The data will continue to be marked as ‘not yet downloaded’, reducing
the chance of it being accidentally deleted later.
•The logger-status LEDs have been indicating an error (red LED will be
flashing every second) for 5 minutes.
•The logger has Bluetooth turned on but there has been no Bluetooth
communication for 30 minutes.
When the communications lead is attached, the logger is powered via USB (see
p. 18)and will not automatically power-off.
The logger will automatically power-up in the following situations.
•The communications lead (connected to a powered PC) is plugged in. The
logger is then ready to communicate with the PC.
•The start button is pressed. The logger will then resume the mode that it
was in when it powered-off, e.g. not-yet-downloaded data will continue to
be protected from accidental deletion.
