What is warm-up time?

This function exhibits the duration of time that has passed since the power was on. If you are measuring temperatures using thermocouples, it is important to take measurements when the inside of the instrument has been adequately warmed up. The warm-up time is displayed on the clock display located in the upper right corner of the main unit for the time period that has been set by this setting. We recommend that you allow 30 minutes or more for the warm-up process.
