PLAY FUNCTIONS
Differential pressure, linear scaling value are displayed.
When this unit monitor is ON, the differential pressure (in
H
2
O) is indicated on the measured data display.
When this unit monitor is ON, the scaling value of an arbi-
trary unit (linear scaling), is indicated on the measured
data display.
This key is used to switch the setting mode and the meas-
urement mode and to change the setting item.
This key is used to change (decrease) and select the set
value .
This key is used to change (increase) and select the set
