Warnings & Cautions

 The infrared camera is a precision instrument and uses a very sensitive IR detector. Pointing the

camera towards highly intensive energy sources-such as sun or devices emitting laser radiation or

reflections from such devices-may affect the accuracy of the camera, or even harm-or irreparably

damage-to the detector, whether the power supply of the camera is switch on or off.

 Avoid incorrect operation methods such as heavy pressing, shock or strong vibration during the

course of transportation, store and installation, otherwise the product could be damaged.

 For protective reason please keep the product in the environment between -25°C and +60°C during

the course of transportation and store. Original packaging box should be used during

transportation.

 For protective reason the camera should be stored in shady, dry and draughty environment avoids

electromagnetic interference.

 Avoid contaminating and damaging the lens surface by oil stain or chemicals. Cover the lens cap

after use.

 Backup is recommended to avoid latent loss of data. Please copy (back up) the data regularly.

 Please take out the battery if the camera out of use for a long time, otherwise the product could be

damaged.

7.2 Quick Operation

7.2.1 Capture an image

Please follow the steps below to capture an infrared image:

step Operation

1 Put the battery in the compartment.

2 Hold the ON/OFF power button to switch on the camera. Then wait for a few seconds to let the

machine start up.

3 Point the camera to a warm object. You can press and hold the ‘F’ trigger to turn on the laser indicator

to exactly locate the target.

4 Adjust the lens ring clockwise or anticlockwise to obtain the best display.

5 Move the target object to the center of the screen, if the target becomes unclear, adjust the lens ring

again to get the best focus.

6 Press and hold down the ‘A’ button to calibrate the focus automatically.

7

If different position is needed to measure, just press ‘S’ button to freeze the image, and press ‘A’

button to select the point, and then move the point to the position of the target.

8

If multiple points need to be measured, or even areas need to be measured, press

to call the

main menu function. Choose ‘Measurement’ to add points, profile and areas to the screen, but there

are 4 points, 1 horizontal or vertical profile, and 3 areas can be added at most. Details can be

consulted in chapter 8.

Note: When the temperature of the target object is higher or lower than the value of corresponding camera
temperature range, the temperature value shown on the screen will be in the form of <XXX°C or >XXX°C.

7.2.2 Color and scale

In some occasions, you may find out that the images you have captured do not appear satisfying.

You can change the color palette prior to saving the image and can change the palette of the image.

There are eleven different Palette scales available.

To switch between the palettes, you just need to press ‘A’ button continually to choose the scale until the
scale is shown in yellow frame. Then press left, right button to switch between the palettes.

Note: you need to press ‘A’ button several times to go to the palette change function. The scale will be
framed in yellow, but not the temperature val ue, the temperature value framed in yellow is used for adjusting
the level and span manually.
