GENERAL
OPERATION
To turn ON your Bullard TXS, depress the green power button located
on top of the unit. The screen will display the Splash screen and the
green power button will illuminate. A thermal image will appear within
a few seconds. This image consists of black, white, and grey ele-
ments which indicate heat signatures of objects and scene dynamics.
Warmer elements appear as lighter shades, while cooler elements
appear as darker shades.
To turn OFF your Bullard TXS, depress and hold the power button until
the “red” power icon located in the top left of the display lights up
and a countdown timer appears until the imager powers off. When the
icon changes from red to green, release and the unit will power off.

ON. In addition, the same LED changes colors to communicate other
system conditions related to charging, as indicated below.

SUPER RED HOT (SRH) COLORIZATION
The Bullard TXS utilizes easy-to-use Super Red Hot colorization which
displays heat levels in yellow, orange, and red hues. This feature iden-
tifies specific heat layers, thus alerting firefighters to areas of intense
heat through visual awareness of the hottest objects in a scene. The
SRH feature automatically adds colorization at temperatures above
500°F/260°C.

800°F - 999°F
427°C - 537°C
> 1000°F
> 538°C
The SRH overlay remains semi-transparent, allowing the scene detail
such as thermal flows to remain visible under the SRH colorization.
SRH has a Heat Color Reference Bar adjacent to the Temperature
Bar. The temperature is illustrated by the filled height of the Tem-
perature Bar and by the Numeric Temperature Indicator below the
bar. The color reference bar is a visual indicator to quickly allow the
user to determine the meaning of the color displayed on the screen.
For example, if the Temperature Measurement Zone is pointed
to an object at 1000°F/538ºC the bar fills to the 1000°F mark.
TEMPERATURE BAR
The Temperature Bar is a bar-graph style temperature gauge in the
right portion of the display. The bar/numeric indicator displayed
represents the approximate temperature of the object viewed within
the Temperature Measurement Zone in the center of the display.
Accuracy of indication is dependent on numerous factors including
the distance from the object being viewed (accuracy decreases as
distance increases) and its emissivity (heat radiation properties).
Your Bullard TXS is factory-calibrated to emissivity corresponding
with normal construction materials. Objects with emissivity varying
greatly from this norm (particularly reflective objects such as met-
als and shiny materials) will see a reduced accuracy of the tempera-
ture indication.
