If a measured value which is adversely affected by rapid changes in the measurement-
gas oxygen concentration is used as the basis for control, frequent on-off actions of the
output may result. To avoid this, the converter allows the setting of output damping
constants ranging from 0 to 255 seconds. Select the appropriate output damping constant
from the numeric-data entry display. To set 30 seconds, enter 030.
You can select linear or logarithmic output mode. The former provides a linear relation-
ship between the analog output signal and oxygen concentration. The latter provides
logarithmic characteristic. Press the [Enter] key in the output mode display. A linear/
logarithmic selection display then appears. Select the desired mode.
• When you select logarithmic mode, the minimum output remains constant at 0.1% O
and the minimum oxygen concentration value remains unchanged.
