Please ensure that you fully charge the battery pr ior to use. T he battery is char ged using the docking station supplied. (See page 7.)

Before using TC7000 consider the objects that you are going to image. Will y ou use comparative thermography (simply looking for temperatur e diff erence) or ar e you going to at tempt to make an accurate tempera ture measurement?

For comparativ e thermography, do not amend th e emissiv ity se tting and leave this const ant ever y time you c arry ou t imaging. Temperature differences over time will then be valid although t he ambient temperature may hav e changed as w ell as the electrical or mechanical load of t he object .

For accurate ther mal measur ement the emissi vity of the objec t will need t o be considered and the c amera emissivit y setting corrected.

In addition background and reﬂected ambient will need to be consid ered as well as thermal and solar reﬂect ion and rela tive humidity.

FOCUS

CRE AT I NG A THERMAL IMAGE

• Correct f ocus is cri tical in pr oducing an

effective thermal image. Slowly rot ate the knur led orange Focus Ring on the front of the lens u ntil the ob ject is clearly in vie w. You may ﬁnd t hat the bes t focus is easier to achie ve using a grey scale pale tte. Make sure th at you focus on the objec t to be measured rather than the background.

• S witch on the TC70 00 by press ing and

holding t he power s witch for at least 3 seconds.

• Ensure auto Level/Span is enable d.

(See S ettings section on P.13)

• Ensure that camera is correctly focused.

• You should now see a h igh qualit y thermal

image and b e able to discern small spa tial and temperature dif ferences.

• Spots (crosshairs) can be moved by using

the joy stick. The temper ature at that point is displa yed on the top left of the display. When th e crosshair is highlighted, pressing and holdi ng the joys tick will a llow the emissi vity of that spo t only to be changed.

T7000 – Intrinsically Safe Thermal Imaging Camera

• Pressing the joystick again will highlight

each spo t in turn. T his is follo wed by the optio n for the TC 7000 to scan for an RFID tag. Place the top f ront of the camera within 5 cm of an RFID tag and press/hold the joystick again. T he RFID tag informa tion will be displayed and can be edited. (See detailed RFID Sec tion on P.11)

MENU SELECTION

• All other camera settings and features are

selected through the menu button. Press this once to display 6 icons.

• When the NUC icon is highlighted one press

of the joystick will perform a manual Non Uniformity Correction (NUC). This should not be required in normal use as the NUC is carried out automatically when required. A distinct click will be heard when the NUC is performed and the thermal image will be refreshed. A manual NUC may be required when moving to different ambient temperatures but very frequent NUC operation will seriously impact battery life.

• When the analysis icon is highlighted

moving the joystick down will cycle through crosshair (spot) selection (0,1,2 or 3), maximum temperature display (within entire image), minimum temperature display (within entire image). (See detailed analysis section on P.12)

• The settings icon enables the user to select

or deselect all of the display settings. (See detailed Settings section on P.13)

• The parameters icon allows all the

measurement parameters of the thermal image to be altered to increase temperature measurement accuracy. These include emissivity, ambient temperature, atmospheric temperature, relative humidity and target distance. (See detailed parameters section on P.14)

• The clock icon enables setting of all time

and date information.

• The info icon displays camera serial number,

internal memory used, remaining internal memory and battery capacity.

RFID ANALYSIS

• When an RFID tag is located an RFID details

menu will be displayed which shows the hexadecimal identiﬁcation of the RFID tag.

• It is recommended that an alias is then

added for future identiﬁcation the tag location . Use the joystick to highlight the alias section (complete with selecting OK) and then input a simple description through the qwerty options (complete with selecting OK - this can be edited later in CorDEX CONNECT)

• Select whether the RFID Tag is built into

a CorDEX IR window (IW2000, IW3000, IW4000) or if it is a stand alone tag (NON CDX).

• With the RFID tag editing complete select

SAVE to store this information for future use.

There ar e three set tings in the analysis menu:

The No. spots icon allows choice of 0, 1, 2 or 3 temperature spots (crosshairs) within the display that will update in real time

The Hi icon enables and disables dis play of maximum tempera ture wi thin the ima ge as a red spo t (crosshair). This temperatur e will be the same as the top of t he tempera ture range in auto span/level.

The Lo i con enables and disables display of minimum t emperat ure within the image a s a blue spo t (crosshair) This tempe rature w ill be the same as the bot tom of the t emperat ure range in auto span/ level.

LEVEL/SPAN STORING AND

ANALYSING IMAGES

• Two settings are fundamental to obtaining

an effective thermal image, the ﬁrst is clear focus and the second is the correct thermal range which is adjusted by Level and Span Settings.

• With Auto Level and Span enabled in the

Settings Menu the range is automatically adjusted to display both the hottest and coldest temperature within the ﬁeld of view.

• When more sensitivity is required level and

span must be set manually by disabling auto level/span in the Settings Menu and using the L+/Land S+/S- buttons on the rear of the camera. Start by increasing the span (sensitivity) to the required setting and then increase or decrease the level (range) so that the object is visible at the required sensitivity.

• The Image Save Button on top of the

handgrip is used to store images (except when periodic save is enabled).

• When you want to save an image, press the

Image Save Button and a Save Image menu will appear. Use the joystick to select yes and press joystick to save.

• If RFID scan is enabled in the Settings Menu

you will be asked to scan an RFID tag to link the saved image to a location.

• If text annotation is enabled in the Settings

Menu you will be asked to select one of 4 pre-programmed text comments. After this the image is stored in the camera memory.

• If voice annotation is enabled in the Settings

Menu you will be asked to record your message. Press the joystick on the Record Button, speak (maximum ten seconds) and then press the joystick on the Stop Button to ﬁnish.

• To review saved images within the camera

press VIEW on the rear of the camera and use the joystick to select the image required. Pressing the joystick will display the stored image full size on the camera display showing all of the parameters displayed when the image was saved. Moving the joystick up and down will change the display colour palette.

TEN SUGGESTIONS FOR THERMOGRAPHY BEST PRACTICE

Ensure that the electrical or mechanical system you are imaging is running fully loaded to highlight thermal anomalies. A fully loaded system will generate higher temperature differential making it simpler to identify problems.

Ensure y our image is in f ocus – this is impor tant not only for ima ge clarit y but also accurate temperatur e discrimination and measur ement. Fo cus should al ways be se t to the obje ct being mea sured eve n if this means that a surrounding area may be out of focus.

If wor king in a Zon e 1 Hazardous area, ensu re that your thermal imaging camera is marked with the appropriate cer tiﬁcation to avoid risk of explosion. Employers are required to identify hazardous areas clear ly for both employees and contractors.

If you ar e looking f or temperatures ab ove or below a temperat ure threshold, use an isotherm or max imum temper ature within an area feature to clearly highlight any excess. These features save tim e and increase awareness as sur veys can take several hours w here fat igue could cause an impor tant anomaly to be overlooked.

Obser ve a scene f rom dif feren t angles to minimise thermal reﬂection as an unusual warm ar ea could jus t be your own thermal reﬂection. Minimise solar r eﬂecti on on display screens outdoors by changing your stance or swivelling the lens to eliminate reﬂection.

Alwa ys conside r the object emissivity ﬁrs t if you want to come close to an accur ate temperature measurement, but remember that r egular comparativ e thermography will also sho w temperature changes leading to potential failure.

For comparative thermography, ensure that thermal camera sett ings and especially emissivit y remain consistent. Ideally system load should also be similar althou gh this is often impractical.

Use inf rared windows to image electrical switchgear under full load in safet y. Never open cabinet doors or override protection devices, this will put you at serious r isk of injur y from arc ﬂash. Even a change of air ﬂow or dust and debris being dislodged can trigger an arc ﬂash incident .

Alwa ys store images and relate them w here possible to visible images whe n building a Repor t. This makes it easier to pinpoin t the fault f or schedul ed maintenance. Choos e a repor ting software packag e that makes this process simple and consider installing RFID tags to link measurements fr om diff erent technologies to one speciﬁc location.

Repor t critical items s eparately in the Report and draw attention to them clearly – t he whole idea of ther mography for preventive maintenance is to ﬁnd faults and ﬁx them before they cause a breakdo wn and loss of production or uptime. Cho ose a repor t sof tware p ackage that create s a scheduled job shee t to pass straight to the maintenance engineer.
