8.2.1 Definition of Equipment States
1. During warm up: “During warm up” is the time required after applying power until the sensor
temperature stabilizes at 750°C, and the equipment is in the measurement mode.
2. Under maintenance: “Under maintenance” is the time starting when the Setup key on the Basic
Panel display screen is pressed until returning back to the Basic Panel display screen. The sub-
screens under the Execution/Setup display screen are included. See Figure 7-4.
