When starting a thermocouple data logger in Tinytag Explorer you will see two
options specific to this type of logger that are not mentioned in the software’s
quick start guide.
Thermocouple Type Thermocouple Type Thermocouple Type Thermocouple Type
Select the thermocouple type you are using from the options listed.
If you are unsure what type of thermocouple you have, the plug or cable on it may
be coloured coded and you can match this to the diagram next to each option.
Colours for the different types of thermocouple are as follows:
Type K

Warnings Warnings Warnings Warnings
• This logger must be used in accordance with the information provided in this
manual.
• This equipment contains a lithium battery. Do not cut open, incinerate,
recharge or expose to temperatures in excess of 100°C (212°F). Danger of
explosion if the battery is incorrectly fitted.
• The battery should only be replaced with the battery type specified in this
document, observing the correct polarity.
•
This equipment should only be connected to a computer using a CAB-0007-
USB interface cable.
• This equipment should be used within the temperature range and other
environmental conditions specified in this manual.
Getting Started Getting Started Getting Started Getting Started
To use a Tinytag Ultra 2 thermocouple data logger you will require the following
items:
• A copy of the Tinytag Explorer software
• A CAB-0007-USB download cable
Install Tinytag Explorer and the USB download cable, as described in the
software’s quick start guide and plug the USB cable into the socket on the front of
the logger.
For further information on how to start the data logger recording and how to view
the results from the unit, please see the Tinytag Explorer quick start guide.

Burnout Response Burnout Response Burnout Response Burnout Response
The burnout response option allows you to tell the data logger what to do in the
event of a problem with the thermocouple being used.
If a faulty thermocouple is attached to the data logger it is possible for the logger
to show readings that may appear to be correct. The burnout response can
deliberately drive readings low or high in the event of a problem, to make it clear
to the user that there is a problem.
Choose what you want the data logger to do from the options listed.
Using the Thermocouple Data Logger

Using the Thermocouple Data Logger
To get the best results, ensure that the data logger and the thermocouple plug
have sufficient time to reach the same temperature before recording begins. If the
thermocouple has been stored at a significantly different temperature from the
logger, allow 30 minutes for stabilisation.
It is advisable to keep the logger at a constant temperature whilst recording, and
to avoid large temperature gradients across the unit (for example, avoid placing
the logger on a very hot or very cold surface).
Large fluctuations in logger temperature can cause temporary errors in the probe
measurement, although these are unlikely to exceed 1°C.
