5.3.1.2 Name (functions)
(1) Measurable component ········ Displays the gas component to be measured in element symbol.
(2) Concentration value
········ Displays measured value of concentration.
(3) Unit
········ Displays the unit of concentration such as ppm, vol%, etc.
(4) Instantaneous
········
value / Average value
Indicates whether the displayed concentration value is instantaneous
value or average value. (The highlighted value is displayed.) Refer to
“6.6.1 Setting of instantaneous/average value” to set instantane-
ous/average value, and “6.5.3 Average value reset” to reset average
value.
(5) Wet / Dry
········ Indicates whether the displayed concentration is wet base or dry base.
Refer to “6.6.2 Wet/dry setting” and “6.7 Analog input” to set wet/dry.
(6) Range display
········ Displays the current full scale range. (The highlighted value is dis-
played.)
(7) Alarm
········ Displays all the alarm occurrence. When more than one alarm has oc-
curred, display is switched by 3 seconds.
(8) O
2
conversion value
········ If components of the HCl meter is provided with O
2
conversion output
when ordering, it displays O
2
conversion. “Conversion**” is displayed
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
2
conversion, refer to “5.3.1.3 O
conversion concentration value”.
(9) Analog input
········ Displays the analog input value which was set at the “AO select”
screen. External input to be displayed are “Temperature”, “Pressure”,
“Velocity”, “O
2
” and “H
2
O”. They are not displayed when selecting
fixed value is selected.
(10) Analog input range
········ Displays the setting range of 4 to 20mA DC which was set at the “AO
select” screen.
(11) Analog input value
········ Displays the analog input value corresponding to the setting range of 4
to 20mA DC which was set at the “AO select” screen.
5.3.1.3 O
2
conversion concentration value
O
2
conversion concentration value is calculated from the following equation of measured component (Cs),
instantaneous concentration of O
2
and O
2
correction reference value.
Conversion output =
21 – On
21 – Os × Cs
●
On: Oxygen conversion reference value (%)
(Value that is set according to application: default value 12%)
●
Os: Oxygen concentration (%)
(O
2
analog input value or fixed value that is set at the “AO select” screen.
In the case O
2
input exceeds the limit value, calculate from the limit value.
(Default value of the limit value: 20%.))
●
Cs: Gas concentration for target component
If you want to change the oxygen conversion reference value and limit value to
other than default value, give instructions before delivery or contact our technical
service representative. After delivery, change is accepted at your expense.
