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 140.40Ω. The value for 500Ω at 0°C will be the
value obtained by multiplying the resistance value in this table by 5.
