NK: Setting switch
Set the flow rate to give an alarm.
The value of the setting switch corresponds to the two digits at center of the LCD.
Ex.
Each time the SET/HOLD switch is pressed, hold of the instantaneous flow rate is started / released.
Even during the hold mode, this Indicator calculates instantaneous flow rate and determines whether to give an alarm
when the flow rate reaches the high / low limit.
When the SET/HOLD switch is pressed for 4 seconds or more, the screen will switch to the constant setting mode.
(The operating procedure specified separately)
* NK has no indication of "H" representing "instantaneous flow rate display."

NK: Constant setting function
Mode No.1 (Set the equivalent value for setting of pulse constant *)
When the SET/HOLD switch is pressed for 4 seconds or more, the screen will switch to Mode No.1 and display the
following.
If no switch is pressed for 10 seconds or more the screen will return to the instantaneous flow rate display. Then, the
setting value of the item where setting is not completed will be invalid.
1. Set the preset equivalent value using the High / Low switch. (Set the value as displayed)
2.
When the SET/HOLD switch is pressed for 2 seconds, the setting value will blink, showing ready for setting.
3.
Set the equivalent value using the High / Low switch.
4.
When the SET/HOLD switch is pressed continuously for 2 seconds, the display will be lit and setting will be
completed.
5.
Set the correct high / low alarm setting value using the High/Low switch. (For preventing malfunctioning of the
alarm)
The right figure shows the relations between the High / Low switch and display digit.
Mode No.2 (Set the EXP value for the equivalent value of pulse constant *)
If the SET/HOLD switch is pressed when Mode No. 1 is lit, the screen will switch to Mode No. 2 and display the
following. ("
" shows the present setting value.)
1. When the SET/HOLD switch is pressed for 2 seconds, the setting value will blink, showing ready for setting.
2. Each time the SET/HOLD switch is pressed, the setting value will change in turn. (Setting value is 0, 1, 2, 3, 4, 5,
6, or 7.)
3. When the SET/HOLD switch is pressed for 2 seconds, the set value will be lit and setting will be completed.
* Mode No. 1 functions as equivalent value, and No. 2, as EXP value. By entering these equivalent and EXP values,
pulse constant can be set. The unit of the pulse constant set by Mode No.1 and Mode No. 2 is L/P. (Refer to Mode
No. 2 of NH for setting examples.)
Mode No.3 (Set the unit of instantaneous flow rate display)
If the SET/HOLD switch is pressed when Mode No. 2 is lit, the screen will switch to Mode No. 3 and display the
following.("
" shows the present setting value.)
1. When the SET/HOLD switch is pressed for 2 seconds, the setting value will blink, showing ready for setting.
2. Each time the SET/HOLD switch is pressed, the setting value will change in turn. (Setting value is 0 or 1.)
(When set to 0, the value is displayed with the unit of "L/min", and when set to 1, "m
3
/min")
3. When the SET/HOLD switch is pressed for 2 seconds, the set value will be lit and setting will be completed.
This shows the setting of the high alarm point to 15.0 Lm/min. When
the display shows 15.0 L/min or more, an alarm will be issued.
This shows the setting of the high alarm point to 3.0 Lm/min. When the
display shows 3.0 L/min or more, an alarm will be issued.
