Note: Desired temperature values are obtained by adding temperatures in the vertical and horizontal axes. When calculating a
resistance value of 105°C, read the value in the column where 100°C in the vertical axis and 5°C in the horizontal axis
cross. The value will be 136.72Ω. The value for 500Ω at 0°C will be the value obtained by multiplying the resistance value
in this table by 5. Similarly, the value for 10Ω at 0°C will be the value obtained by dividing the resistance value by 10.
