DISPLAY OVERVIEW
DESIGNATION FUNCTION
Measured data
display
Differential pressure, linear scaling value are displayed.
Differential
pressure unit
monitor
When this unit monitor is ON, the differential pressure
(in H
2
O) is indicated on the measured data display.
Scaling; arbitrary
unit monitor
When this unit monitor is ON, the scaling value of an
arbitrary unit (linear scaling), is indicated on the
measured data display.
MODE key M
This key is used to switch the setting mode and the
measurement mode and to change the setting item.
DOWN key S
This key is used to change (decrease) and select the
set value.
UP key T
This key is used to change (increase) and select the set
value and to shift from the measurement mode to the
zero adjustment mode.
