8.3 Output Hold Setting

The “output hold” functions retain an analog output signal at a preset value during the equipment’s

warm-up time or calibration or if an error arises.
Table 8.4 shows the analog outputs that can be retained and the individual states.

8.3.1 Definition of Equipment Status

(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. This status is that the

sensor temperature is displayed on the basic panel.

(2) During maintenance

“During maintenance” is the time from when a valid password is entered in the basic panel

display to enable the parameter code selection display until the display goes back to the basic

panel display

(3) During calibration (see Chapter 9, Calibration)

In the manual calibration, proceed with the calibration operation with the parameter code

「B10」 to display the span gas confirmation display for the first span calibration, thus starting the

calibration time when the [ENT] key is touched. After a series of calibrations is complete and the

preset output stabilization time has elapsed, the calibration time will be up. Figure 8.1 shows the

definition of “during calibration” in the manual calibration.
