Introduction

The Raytek ThermoView Ti30 imager is a state-of-the-art, lightweight, gun-grip
style thermal imaging unit that lets you obtain instant and accurate thermal images
and radiometric readings at a remote distance from your target. Ergonomically
designed for either left or right-handed use, the ThermoView imager captures
thermal images and data with a simple click of the trigger. The unit can store up to
100 images that can then be downloaded to your personal computer where the
images can be stored, evaluated further or added to reports and presentations.

The ThermoView’s docking station allows effortless connection to a host computer,
and offers rapid data downloading and uploading. The docking station also
automatically recharges the (rechargeable) batteries when the unit is not in use.

The companion software application, InsideIR, included with the imager lets you
display, examine, and analyze your images and data to discover qualitative and
quantitative trends associated with the target. InsideIR software allows you to define
maintenance databases based on your specific equipment condition, monitoring, and
asset management needs.

The ThermoView imager contains 100 image storage locations that can also be
predefined with unique equipment data and parameters. Notes and comments can
also be included for the technician performing the given maintenance routine.
Maintenance reports and follow-up actions can be created quickly and accurately
using information carried over from image files. Reports can be easily printed or sent
electronically.

Using the ThermoView imager’s structured database, maintenance professionals can
ensure consistent, repeatable measurements over time. They can efficiently and
accurately communicate with co-workers, management, equipment manufacturers,
and service providers by incorporating thermal images in emails and reports. In
addition, customers can easily create permanent inspection records indicating
temperature behavior before and after repairs, and monitor thermal trends over long
periods.

We are confident the ThermoView Ti30 imager is both an easy-to-use, yet powerful,
thermal imaging tool on the market today. We know you will find it a valuable and
indispensable tool for your workplace and for your professional growth.

Chapter 2 Getting Started

Your ThermoView imager has settings and capabilities that let you customize its
operation for the task at hand. The following section describes each setting on the
imager.

Attaching the Wrist Strap

Your ThermoView imager comes with a wrist strap, which can be attached by
clipping the metal part of the strap to the small metal bar at the base of the imager
(see Figure 5 below).

Attach wrist strap

Figure 6. Powering the ThermoView Imager On and Off

Note:

Important:

The unit is self-protected against excessive levels of infrared radiation and it will
cause the unit to automatically shut down. If that happens, slide the lens door
closed, wait a minute and slide it open again.

Always dock the imager in the docking station when not in use. By doing so,
you will assure the batteries will be always fully charged when using the
rechargeable battery pack. The image will not show thermal images or
respond to controls while it is in the docking station.

Displaying Images

The ThermoView imager performs an initial auto-check each time it is activated and then
immediately shows the Information Screen. The Information Screen displays the
following information about the ThermoView imager unit:

Figure 8. Normal Mode

Take time to experiment with the imager and become familiar with how the thermal image is
updated on the display as you aim the imager at different targets with different thermal
patterns. Notice how images display in varying colors, which are related to the different
target temperatures. The color scale at the bottom of the thermal image shows the minimum
and maximum temperature value in the thermal scene at any moment. These values will
change as you point the imager at other targets, or if the temperatures of the current target
change. The sequence or progression of different colors along the color scale indicates the
distribution of the different temperatures on the thermal scene. Notice how the colors along
the beginning of the color scale represent lower temperatures and colors along the end of
the color scale represent higher temperatures.

Note:

The ThermoView imager settings can be customized for your particular application. The
following sub-section reviews the settings and controls.

At this point you probably have noticed that the image freezes briefly from time to
time while an hourglass icon is briefly displayed. This is a normal process that
happens when the unit momentarily shuts down the optical channel to eliminate
offset errors. This is a recalibration sequence that begins immediately after the unit
is turned on. Recalibration occurs at 5 seconds, then 10 seconds, then 20 seconds,
then 30 seconds and then finally at every other minute. It is a good idea to keep the
unit On if you are using it constantly over a period of time to avoid resetting the
recalibration procedure counter.
