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.
Specifications given herein may be changed at any time without prior notice. Please confirm technical specifications before you order and/or use.
