4. OPERATION
1st Edition : Oct. 27, 2023-00
4.4 General operation of display/operation panel
(1) Measurement screen (This screen always appears when the power is
turned on.)
The measurement screen varies depending on the number of components. The following screen
configuration is an example of NOx (1 component channel) and NOx, SO
2
, CO, CO
2
, and O
2
(12
component channels).

Example1: NOx (Component1 channel)
If there are more than 6 channels of components or more than 5 ch peak alarm displays, you can scroll through them
with the
icons.

*1: For NO, SO
2
, and CO components, if each measuring range is specified in ppm and the option “/U” (Unit change) is selected,
the units are displayed in mass units (mg/m3 or g/m3). However, if the calibration gas concentration is specified in ppm, the
calibration gas concentration on the calibration-related screen will be displayed in both ppm and mass units.
*2: Peak alarm-related displays are only shown when the Peak Alarm option (/A) is specified and the function is ON. (See 5.1.7
Peak alarm setting“ for the function settings.
● Instantaneous concentration value: gas component such as “CO
2
”, “CO”, “O
2
”
indicate what gas component is currently
being measured and each corresponding
instantaneous concentration value
