6. Operation and Parameters
The OX400 has two modes, “Measurement Mode” and “Maintenance Mode.” Oxygen concentration
is displayed in the measurement mode. The setting of operation parameters and calibration operation
are performed in the maintenance mode. Furthermore, the MODE LED on the front panel is on in the
maintenance mode. To enter the maintenance mode, or to return to the measurement mode from the
maintenance mode, hold down the [ MODE] key for two seconds. The parameters shown in Figure 6.1
are available in the maintenance mode. Parameters can be displayed by scrolling with the [▼], [▲]
keys.
