8.3.11 Integral Indicator Scale Setup
The following three displays are available for the
integral indictor: differential pressure/pressure,
static pressure, and temperature. The following
three variables can be displayed on the integral
indicator: % of differential pressure range, % of
static pressure range, and % of temperature range.
Available displays
Description
and related parameters
% of range
(PRES %)
Indicates input pressure in –10 to
110% range depending on the set
range ( LRV and URV).
PRES % 45.6 %
% of static pressure
range (SP %) *1
Indicates input static pressure in
–10 to 110% range depending on
the set range ( SP LRV and SP
URV).
SP % 52.6 %
*1: Available for differential pressure transmitter.
Follow the procedure described in (1) to (2) below
to set the integral indicator.
(1) Display Selection
Display set to Display Selection is displayed on the
integral indicator.
• Procedure to call up the Display Selection
display
TRANSDUCER block: Display Selection
The Display Selection parameter enables
the differential pressure/pressure (AI1 block),
static pressure (AI2 block), and temperature
(AI3 block) to be displayed on the LCD. Select
whether or not to enable each block to be
displayed
(2) Cyclic Display
Information in the AI1 to AI3 blocks can be
displayed cyclically according to the display On/Off
setting for the differential pressure (AI1 block), static
pressure (AI2 block), and temperature (AI3 block)
selected in the Display Selection parameter.
8.3.12 Unit for Displayed Temperature
When the instrument is shipped, the temperature
units are set to C (Centigrade). Follow the
procedure below to change this setting.
• Procedure to call up the Sensor Range.Units
Index display
AI3 block : Sensor Range.Units Index
Confirm that °C(deg C) is selected in the
Sensor Range.Units Index parameter for the
temperature (AI3 block).
Note: When the unit is changed by Sensor Range.Units Index
parameter in temperature ( Al3 block) , units of capsule
temperature is also changed.
8.3.13 Unit for Displayed Static Pressure
Follow the procedure to change the static pressure
unit.
Changing this parameter also changes the unit for
the static pressure display.
• Procedure to call up the Sensor Range.Units
Index display
AI2 block : Sensor Range.Units Index
Confirm that KPa is selected in the Sensor
Range.Units Index parameter for the static
pressure (AI2 block).
Monitoring the high or low static pressure of the
capsule depends on the setting of parameter
‘SP Select.’
• Procedure to call up the SP Select display
AI2 block: SP Select
Select High or Low in the SP Select parameter
for the static pressure (AI2 block).
Type of static pressure is set Absolute
pressure(Abs) at shipment.
When changing monitoring type of static pressure,
Follow below procedure.
• Procedure to call up the Static Press Type
display
AI2 block: Static Press Type
Select gauge pressure (Gauge) or absolute
pressure (Abs) in the Static Press Type
parameter for the static pressure (AI2 block).
