1.3 Safety Warnings and Exclusions

All users of ISG INFRASYS Thermal Imagers must read the following safety warnings and exclusions carefully.

1) ISG INFRASYS thermal imagers must only be used by personnel familiar with the usage and limitatio ns of a thermal imaging camera, including a g eneral understanding of thermal images and how they are interpreted. It is recommended that the user has gained experience with its usage in simulated fire condit ions, such as a controlled live burn situation. Usage of the ISG INFRASYS thermal imager by unauthorised, unfamiliar or untrained users in a hazardous atmosphere may result in injury or death.

2) The ISG INFRASYS thermal imager is not life support equipment and should not be used as such.

3) The ISG INFRASYS thermal imager provides a thermal image in normal visionimpairing conditions and is designed to augment your existing Standard Operating Procedures. Failure to follow Standard Operating Procedures in a hazardous atmosphere may result in disorientation, injury or death, in the unlikely event t hat the equipment should fail.

K250 / SD250 Operating Manual

4) Always perform a visual check on the equipment prior to use to vali d ate that it has not been damaged or degraded.

5) Never use the ISG INFRASYS thermal imager as the sole source of navigation. If system failure occurs, you may become disoriented or lost in a hostile environment, which could result in injury or death.

6) The ISG INFRASYS thermal imager is a complex, electro-optical piece of equipment and, just like any other piece of machiner y or elect ronic sy stem, is s ubject to potential failures. Should a failure occur, the user will no longer have access to the thermal images provided by the thermal imager. Tactical usage of this equipment must not deviate from Standard Operating Proced ures used by personnel who do not have the benefit of the equipment.

7) While every effort has been made to ensure that your ISG INFRASYS thermal imager is both tough and reliable, the thermal imager is a sophisticated electro-optical system that will fail if it is abused or exposed to environments beyond its design envelope.

3.4 ICETM – Intellige n t C ontrast Enhan cement

ICETM* (Intelligent Contrast Enhancement) is a p atented innovation from ISG INFRASYS. This technology operates to automatically enhance background cont rast when viewing ex tremely ho t objects. This improves visibility for t he user as hot objects and cooler surroundings are clearly visible simultaneously. The extra information is vital when viewing extreme temperatures in Thousand-Plus Mode and increases the effectiveness of firefig hting, whilst enhancing safety for the firefighter.

The adjacent image captured in Thousand-Plus Mode illustrates how ICE

TM*

improves visibility in

practice –

1) The detail in the fire is clearly displayed whilst;

2) The background is maintained in high contrast.

* Patent No. GB2435977

3.5 ICE

Sensitivity Mo des

The ICETM system thermal imager incorporates two distinct sensitivity modes and selects the appropriate mode automatically by analysing the thermal characteristics of the scene.

Normal Mode

‘Normal Mode’ is automatically selected when viewing low to medium ambient temperature scenes and/or when there is little burning material in the scene.

In this mode the thermal imager’s sensitivity is optimised to maximise the clarity of the lowertemperature parts of the scene, enabling cryst al-clear imaging of the ambient scene as well as displaying small, localised hotspots up to 500

C without

saturation.

Thousand-Plus Mode

‘Thousand-Plus Mode’ is automatically selected when viewing extreme heat conditions, for example, in flash over situations or other extreme emergency situations where safety could be compromised.

In this mode the dynamic range is set to maximum to provide clear imaging of scene temperatures in excess of 1000 °C without saturation, designed to allow easy analysis of structures and burning materials while retaining excellent visibility of low-

K250 / SD250 Operating Manual

temperature background detail to facilitate rapid egress.

Note

When the thermal imager switches mode, a momentary interruption of the displayed image may be experienced.

3.6 Colour Temperature Scale Indicator

The graduated scale colour palette provides a visual indication of the range of scene temperatures detected, enabling rapid recognition of hot spots.

ICE

(Intelligent Contrast Enhancement) Single

Palette Colour Temperature Scale Indicator.

3.7 Direct Temperature Measurement (DTM)

1) Aim the cross wire dir ectl y over t he obj ect to be measured.

2) Read the temperature.

Notes

The measured temperature is based on an assumed target emissivity of 0.95.

The measurement indicated is not a measure of air temperature.

Unless specified otherwise at the time of order, the unit of measuremen t, in terms of degrees Centigrade or Fahrenheit, is preset at the factory to the normal standard for the designated country.

In order to obtain a temperature measurement o f a hot object in a scene, the thermal imager may switch between different sensitivity modes, dependent on the scene conditions at the centre of the cross wire. This is complet ely normal and the thermal imager will revert to the appropriate sensiti vity mode once the hot object is removed from the scene.
