Docking Station

Normal Charge Cycle

x With the ThermoView unit powered off, place it on the docking station.

x Do not connect the USB cable to the computer at this point.

x The red LED (on the left) will flash several times as the circuit senses a rechargeable

battery pack and determines its state of charge.

Note:

If a non-rechargeable battery pack is sensed by the docking station, neither LED
will blink.

The remaining points assume that the imager contains a sealed, rechargeable battery pack.

x The red LED turns on continuously to indicate that charging is in progress. This process

can take from a few minutes to more than an hour.

x The red LED turns off once the battery pack is fully charged and the green LED (on the

right) turns on continuously.

x Momentarily lifting the ThermoView unit from the docking station for about 5 seconds

or longer interrupts the charging process. The green light will come on and no further
charging will occur. Press the Restart / Sync button between the LEDs to resume
charging. Pressing the button if the batteries are completely charged will have no effect.

x The imager may be removed from the docking station before recharging is completed

without harm. However, the imager may not be fully charged and its operating time may
be reduced accordingly.

x An imager containing single-use batteries may safely be placed on the docking station for

storage or image transfer. In fact, we recommend the imager always be placed on the
docking station when not in use.

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:

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.

Important:

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:

Temperature scale

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:

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.

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

i

i

Tel: [phone]- WWW.ISSLTD.CO.UK - Fax: [phone]

There are three measurement mode positions associated with this switch:

Automatic Semi Automatic Manual

In Automatic mode the ThermoView imager automatically adjusts the image to show
the lowest temperature value present in the thermal scene (MIN) and the highest
temperature value in the scene (MAX).

In

Semi-Automatic mode the ThermoView imager keeps calculating the MIN limit

(lowest temperature value on the thermal scene) automatically.

In Manual mode the user can adjust Gain and Level manually.

See Selecting the Measurement Mode on page 42 for more information. The default position
is automatic mode.

Gain and Level Thumbwheels

The Level Thumbwheel control adjusts the median point of a given temperature
scale.

The Gain Thumbwheel control adjusts the temperature band around the median
Level point.

See Gain and Level Thumbwheels on page 45 for more information about these controls.

Focus Wheel

The Focus Wheel is located on the bottom of the imager’s housing in from of the trigger as
shown in Figure 14. Adjust the focus by turning the Focus Wheel with your fingers or
thumb.
