5.3.1.2 O
conversion concentration value

O
conversion concentration value is calculated from the following equation of measured component (Cs),

instantaneous concentration of O
Conversion output =
······ Displays the measured concentration. The value is reversed during the
value is held and during automatic calibration of laser waveform is in
operation.
······ Displays the unit of concentration such as ppm, vol%, etc.
······
Indicates whether the displayed concentration value is instantaneous
value or average value. (The reversed value is displayed.)
······ Indicates whether the displayed concentration is wet base or dry base.
(The reversed value is displayed.)
H
O is fixed to "Wet".

······ Displays the current full scale range.
······ Displays all the alarm. When more than one alarm has occurred, dis-
play is switched by 3 seconds.
······ If components of the HCl meter is provided with O
when ordering, it displays O
as "Conversion HCl" on the display area. For changeover of instanta-
neous value/average value or wet/dry, display and analog output can
be performed independent of the original conversion on "Display /
Output" screen. For the contents of O
conversion concentration value".
······ Displays the analog input value which was set at the "Analog Input"
screen. Analog input to be displayed are "Temperature", "Pressure",
"Velocity", "O
fixed value is selected.
······ Displays the setting range of 4 to 20mA DC which was set at the "An-
alog Input" screen.
······ Displays the analog input value corresponding to the setting range of 4
to 20mA DC which was set at the "Analog Input" screen.
······ Displays current level of AGC. (when using High-speed AGC version
i.e. the 22th digit of type code is "H", or CO + O
digit is "V", "U", or "S")
······ displays the percentage of the light transmitted through gas.

In the case O
input exceeds the limit value, calculate from the limit value.
