according to the screen display until the display returns to the main screen. 

 

Current Data Menu Display 

Display Description 

1 Total Volume 

Displays the total flow rate. 

2 Flow Rate 

Displays the suction flow rate (average, fluctuation coefficient). 

3 Sample Time 

Displays the sampling start date/time. 

4 Ambient BP. 

Displays the ambient pressure (minimum, maximum, 30-second average). 

5 Pressure Drop 

Displays the filter pressure loss   
(minimum, maximum, 30-second average). 

6 Temperature 

Displays the ambient temperature   
(minimum, maximum, 30-second average). 

7 Warning 

Displays the warning (flow rate fault, sampling time fault, power failure). 

*  Each of the measurement values for "suction flow rate," "ambient pressure," 

"pressure loss," and "temperature" is displayed 30 seconds after sampling is 
started and their values are updated at 30-second intervals. "0" (zero) is 
indicated for each of these measurement values until 30 seconds has elapsed 
since sampling was started. 

 
 

 

Total Volume (Total Flow Rate) 

When "1 Total Volume" is selected and the [ENTER] key is pressed, the total flow rate is 
displayed. 
On the last line, for the actual volume flow rate, "Actual VF" is displayed, and for the volume flow 
rate after conversion to the standard state, the standard temperature and "Standard VF" are 
displayed. (

 For details, see P33 and P45.)   

 

 

Flow Rate (Suction Flow Rate) 

When "2 Flow Rate" is selected and the [ENTER] key is pressed, the Flow Rate menu is 
displayed. When "AVG." is selected by the [UP] and [DOWN] keys and the [ENTER] key is 
pressed, the average flow rate since sampling was started is displayed. Likewise, when "CV." is 
selected and the [ENTER] key is pressed, the fluctuation coefficient of the suction flow rate since 
sampling was started is displayed.   

 

 

Sample Time (Samoling Time) 

When "3 Sample Time" is selected and the [ENTER] key is pressed, "1 Start" is displayed. When 
the [ENTER] key is pressed again, the date/time when sampling was started is displayed. 

 

 

Ambient BP. (Ambient Pressure) 

When "4 Ambient BP." is selected and the [ENTER] key is pressed, the Ambient BP. menu is 
displayed. When "MIN.," "MAX.," and "30sec AVG." are respectively selected by the [UP] and 
[DOWN] keys and the [ENTER] key is pressed, the respective ambient pressure minimum value, 
maximum value and 30-second average value since sampling was started are displayed.
