When calculating a resistance value of 105C, read the value in the column where 100C in the vertical axis and 5C in the horizontal axis cross. The value will be 140.40. The value for 500 at 0C will be the value obtained by multiplying the resistance value in this table by 5. Similarly, the value for 1K at 0C will be the value obtained by multiplying the resistance value by 10. Specifications given herein may be changed at any time without prior notice.
