Definition of Equipment Status

The "output hold" functions hold an analog output signal at a preset value during the
equipment's warm-up time or calibration or if an error arises. Outputs 1 and 2 can be set
individually. Table 8.1.2 shows the analog outputs that can be retained and the indi-
vidual states.

"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 for pressing the Setup key in the basic panel
display the Execution/Setup display, to go back to the basic panel display. The display

"Under calibration" is the time, during manual calibration, starting from entering the
Manual calibration display (shown in Figure 8.1), and making a series of calibrations,
until the Calibration End key is pressed or until the preset output stabilization time
elapses.
