8.1.2

Entering Output Damping Constants

If a measured value which is adversely affected by rapid changes in the process is used
as the basis for control, frequent on-off actions of the output may result. To avoid this,
the analyzer allows the setting of output damping constants ranging from 0 to 255
seconds.

8.1.3

Selection of Output Mode

There are two output modes available: linear mode and logarithmic mode. Select the
either mode for your desired analog output vs. measured value characteristics.

CAUTION

• When you select logarithmic mode, the minimum output remains constant at 0.1% O

,

and the humidity remains set to 0.1% H

O and mixing ratio is set to 0.01 kg/kg,

regardless of the set values. Set value of C11 to C16 remains unchanged.

8.1.4

Default Values

When the analyzer is delivered or data are initialized, the output current settings are by
default as shown in Table 8.2.
