calculations. If a Temperature Transducer will be used to input
process temperature into the transmitter, it is not necessary to
enter a temperature.
Pressing the ↓ key will next display ‘→Pressure Sel’ on Line 2. If
an external pressure sensor will not be used to input pressure to
the transmitter,
‘Fixed’ appears on line 4. If set to ‘Fixed’ pressure
input, use the
↓ key to scroll to the next menu item. However, if an
external pressure sensor will be used to input pressure to the
transmitter press ‘ENTER’ and use the ↓ key to select either
‘Sensor #1’ or ‘Sensor #2’. (‘Sensor #1’ or ‘Sensor #2’ refers to
the sensor input the temperature transducer is wired to on the
terminal block in the transmitter enclosure.) If the Modbus input is
to be used to input pressure to the transmitter use the
↓ key to
select ‘Protocol’. Once the selection is made, press ‘ENTER’.
Pressing the ↓ key will next display ‘→Temperature Sel’ on Line 2.
If an external temperature sensor will not be used to input
temperature to the transmitter,
‘Fixed’ appears on line 4. If using
‘Fixed’ temperature input, use the ↓ key to scroll to the next menu
item. However, if an external temperature sensor will be used to
input temperature
to the transmitter press ‘ENTER’ and use the ↓
key to select either ‘Sensor #1’ or ‘Sensor #2’. (‘Sensor #1’ or
‘Sensor #2’ refers to the sensor input the temperature transducer is
wired to on the terminal block within the transmitter box.) If the
Modbus input is to be used to input temperature to the transmitter
use the
↓ key to select ‘Protocol’. Once the selection is made,
press ‘ENTER’.
Pressing the
↓ key will next display ‘→Altitude’ on Line 2 and the
selected value above (or below) sea level on Line 4. To change
the Line 4 value press ‘ENTER’ and use the arrow keys to enter
the new value. Note: if an external pressure transducer that reads
pressure in ‘absolute’ value (e.g. PSIa, BARa, or KPaa) is used, an
altitude correction is not necessary.
Pressing the ↓ key will next display ‘→Calibration’ on Line 2.
Press the ‘ENTER’ key and ‘→C0’ will appear on Line 3 and a
numerical value on Line 4. Press the ‘ENTER’ key and use the
arrow keys to enter the calibration factors that will accompany the
sen
sor. Once the ‘C0’ value is entered press the ‘ENTER’ key to
store that value to memory. Line 3 will show ‘→C0’; press the ↓
key to move to
‘→C1’, press ‘ENTER’, and use the arrow keys to
enter ‘C1’ values. Once the values are entered, press ‘ENTER’
and press the
↓ key to move to ‘→C2’ and enter those values and
press ‘ENTER’ and the ‘BACK’ key.
The display will show ‘→Calibration’ on Line 2. Press the ↓ key to
scroll to
‘→Flow Direction’ on Line 2. If it is necessary to change
the flow direction (if the sensor was installed with the Flow
