6-2-1. Setting of calorific value calculation conditions
(CALCULATION FACTOR (CALORIFIC VALUE))
Set the calorific value calculation conditions. In the menu screen, press the SET key to display the setting
value check screen and display the current settings of calculation conditions. Next, press the SET key to
highlight the line indicating the calculation method in reverse video and enable selection of a calculation
method using the
▲▼ + SET keys.

The figures above are examples in which Opt-Sonic calculation is set. The available calculation methods
and characteristics are shown in the table below.
Opt-Sonic calculation
This method effectively suppresses the influences of
interference gases on the measuring results of the optical and
sonic sensors through calculation processing.
The calculation factor
α must be set according to the major
fluctuating components of interference gases.
Optical sensor calculation
This method calculates calorific values using only the optical
sensor. The calorific value measurement using only the optical
sensor is relatively less influenced by interference gases.
Therefore, this method can also be used for measurement if
there is a small amount of interference gases.
Sonic sensor calculation
This method calculates calorific values using only the sonic
sensor. The calorific value measurement using only the sonic
sensor is significantly influenced by interference gases.
Therefore, this method is not recommended unless there are
unavoidable circumstances.
After "OPT-SONIC CALCULATION" is selected as the calorific value calculation method, the calculation
factor
α setting screen is displayed. Set a numeric value using the ▲▼ keys, and confirm the value using
the SET key.
