This is done by simply turning the adjuster until an accurate reading is reached. • Stir slightly, then wait until temperature indicator on the thermometer is stabilized. Black bodies approximate zero reflected ambient radiation and therefore the unimpeded emission of infrared energy for a given emissivity value (typically 0.95). is full. To calibrate your infrared thermometer with an ice bath: Step 1: Fill a large glass to the very top with ice (crushed ice is preferred but not required). However, you will find others with a nut under the temperature dial to make adjustments.
