Example 3: Scaling with Current/Voltage Transducer (Process) Input.
The following example include details for a specific scenario in
which a 4 - 20 mAinput is to be represented as a measurement
of 0 - 100 percent.
Press d41) Press dat the IN.RD prompt. Display shows
IN!1
Input 1
Submenu.
Press d
42) Display shows Input 1 value with 1st digit flashing.
Press b& c43) Use band cbuttons to enter
IN!1
value.
The
IN!1
value = min. input value x conversion number
from Table 3.1
Enter 4 mAas 4 (mA) x 500 = 2000
Press d44) Display advances to
RD!1
Reading 1 Submenu.
Press b& c45) Use band cbuttons to enter
RD!1
value.
This value corresponds to Input 1 in terms of some meaningful
engineering units. To show 4 mAas zero percent enter
RD!1
value = 0000.
Press d46) Display
IN!2
Input 2 Submenu.
Press d47) Display shows
IN!2
Input 2 value
with 1st digit flashing
.
The
IN!2
value = max. input value x conversion number
from Table 3.1
Enter 20 mAas 20 (mA) x 500 = 10000 (entered as 9999)
Press b& c
48)
Use band cbuttons to enter
IN!2
value.
Press d49) Display advances to
RD!2
Reading 2 Submenu.
Press b& c50) Use band cbuttons to enter
RD!2
value.
To show 20 mAas 100 percent enter
RD!2
value = 0100
Press d51) Display flashes STRD stored message momentarily and
then advances to ALR1 only, if a change was made, otherwise
advances to ALR1 Alarm 1 Menu.
