- Figure 1. An ordinary BJT Q1 makes an accurate 100 µV per unit Kelvin absolute temperature sensor
- Figure 2. A zero drift, 5 µV max offset A1 rescales 100 µV/°K by 10x to 1 mV/°C and by 18x to 1 mV/°F
- Figure 3. Connect the DMM's plus lead to the appropriate figure 2 output, and the minus lead to the correct precision 0° offset terminal, to re-zero 273K to 0°C and 460R to °0F
