Setting or changing the damping time constant
BASIC MENU 3 <Damping Time>
Conduct the setting of damping for 4 - 20 mA output and LCD display.
Values that can be set are classified into the following 12 types:
1: 0 s 7: 4 s
2: 0.16 s 8: 8 s
3: 0.32 s 9: 16 s
4: 0.48 s 10: 32 s
5: 1 s 11: 64 s
6: 2 s 12: 128 s
Press the [Menu] key (M) once to display the message “BASIC MENU.”
Press the key once to display the message “1 <Main Disp>.” Press the key twice
to display the message “3 <Damping>.” Next, pressing the key causes the system
to display “1: 0.00 s.” Select the damping time constant by using the or key and
press the [Enter] key (E). When the message “Value Changed” appears, the setting is
completed.
Setting or changing a low flow cut value
BASIC MENU 4 <Low Flow Cut>
Conduct the setting or changing of the low flow cut for 4 - 20 mA output, LCD
display value and totalized (cumulative) value.
The values that can be set are any values in the proportion of 0 to 20% of the flow
rate range that has been set.
Press the [Menu] key (M) once to display the message “BASIC MENU.”
Press the key once to display the message “1 <Main Disp>.” Press the key three
times to display the message “4 <Low Flow Cut>.” Pressing the key moves the

Setting and executing the leak checking function
BASIC MENU 5 <Leak Check>
Conduct the display of leak rate, resetting of measured values, and setting of
compressor pressure.
The range of pressures that can be set is 0.3 to 0.98 MPa. For the details, refer to the
Item “Leak checking function” under Chapter 4, Subsection 4-11 “Explanation of
some important functions.” Items that can be handled by this function are as follows:
Leak Rate Displays a leak rate.
Reset OK? Deletes the data for determining a leak rate.
Set Press Conducts the compressor pressure setting.
Press the [Menu] key (M) once to display the message “BASIC MENU.”
Press the key once to display the message “1 <Main Disp>.” Press the key four
times to display the message “5 <Leak Check>.” Pressing the key moves the “1:
Leak Rate” cursor. Select the items to be set by using the or key.
