Setting Alarm threshold, Unit and Emissivity You can set a defined alarm threshold. As soon as the defined alarm threshold is exceeded, an alarm is issued. You can change the unit. You can set the emissivity. 22 / 41 MRU GmbH, D-74172 Neckarsulm... - Page 23 However, metals, especially those with polished or shiny surfaces, can have an emissivity of 0.1 and are poorly suited for IR measurement. Set the corresponding emissivity before the measurement. Otherwise, there may be large deviations in the measurement. 23 / 41 MRU GmbH, D-74172 Neckarsulm...
- Page 24 The emissivity given here serve as a rough orientation and may vary greatly depending on the variation of the material (e.g., not oxidized to oxidized).
