Attention: • When the meter is in operation, a slight clicking sound can be heard every few seconds. This is normal and means that the IR sensor is sensing the surroundings. • Do not place the meter directly near a strong heat source. •...
Display description Set emissivity Image centre temp. Battery level Lowest temp. mark Colour palette Centre mark Highest temp. mark MAX and MIN Current time temperature values Lowest temperature mark The green mark appears where the lowest temperature is measured. The minimum measured temperature is also displayed in the middle of the bottom line as the MIN value.
Charge / replace battery 3.4.1 Charge battery The PCE-TC 33N thermal imaging camera has a built-in rechargeable Li-Ion battery. If the battery level is low, this is indicated by the battery status icon at the top right of the display. In that case, charge the battery via the micro USB interface.
Operation Switching the unit on and off Press and hold the ENTER key for more than 3 seconds to switch the thermal imaging camera on or off. After switching on, the lens cover must be opened. The display then shows the thermal image of the targeted area.
Submenus 4.3.1 Image registration / Adjust IR image and general image It may happen that the infrared image and the normal image on the display do not overlap completely. This can be corrected via the menu "Image registration". Press the MENU key. A selection list of submenus appears. The current function is highlighted in blue.
Description of the colour palettes Different colour palettes can be used to display the temperature differences of the infrared image. The PCE-TC 33N offers five colour palettes common for thermographic images: spectrum (rainbow), iron, cold, white (hot), black (hot). The coloured palettes work best with large temperature differences and provide additional coloured contrast.
Emissivity 4.6.1 Desscription of the emissivity Every object with a temperature above absolute zero emits thermal radiation. The emissivity is the indicator of how much thermal radiation this object emits in contrast to an ideal thermal radiator, the black body. The emissivity is therefore always between 0 ... 1 (0 ... 100 %). For many applications, it is sufficient to measure with the standard value of 0.95.
