Training optional, but you must feel confident in the use of the device and must have read the equipment instructions.
The thermal imager is a special sort of camera used for viewing the heat given off by an object. This could be used to identify a short circuit by looking for hotspots, or parts of a circuit that are not working properly (cold areas). Another use is for identifying parts of machinery that need lubrication since those with too much friction will appear warm.
To use the imager, press the red power button for 2 seconds and wait for the imager to become ready. Hold the red button for 2 seconds and click "OK" on the touch screen to turn it off.
The imager must be focussed for each subject so turn the rubber ring around the lens to do this. Click the trigger to take a photo but make sure you press the tick on the touchscreen to save it. Click again to return to the live view.
Video can be recorded by holding the trigger for at least 2 seconds and then releasing. Just click the trigger to stop recording. Images can be viewed by removing the micro SD card (look in the top rubber cover) and inserting into a computer.
The resolution is 320x240 and it can measure temperatures from -20 to +150 and from 0 to +650 degrees C. There is a menu option to select which of these ranges to use.
If using the imager for long periods of time, use the supplied mains adapter with USB-C cable to power it. Note that plugging the imager into a laptop will not allow simultaneous charging and use of the imager; the mains adapter must be used instead.
• Point at the sun or other intense energy sources.
• Force the box closed - the manual must be laid flat in the correct place before closing.
• Use it to measure temperature of visually reflective things (e.g. shiny metal) as they also reflect heat and do not emit much of their own (low "emissivity").
• Touch the lens.
• ALWAYS use the green wriststrap; the thermal imager is a valuable item that we do not want to be dropped!
• Read the manual if you wish to change any of the imager's settings.
• Charge the thermal imager on the electronics workbench if it has run out of power.
• Read up on emissivity if you require accurate temperature readings.
