Example 3: Scaling with Current/Voltage Transducer (Process) Input.
The following example include details for a specific scenario in which a 4 - 20 mA input is to be represented as a measurement of 0 - 100 percent.
Press d 41) Press d at 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 & c 43) Use b and c buttons to enter IN!1 value.
The IN!1 value = min. input value x conversion number from Table 3.1
Enter 4 mA as 4 (mA) x 500 = 2000
Press d 44) Display advances to RD!1 Reading 1 Submenu. Press b & c 45) Use b and c buttons to enter RD!1 value.
Press d Press d
This value corresponds to Input 1 in terms of some meaningful engineering units. To show 4 mA as zero percent enter RD!1 value = 0000.
46)Display IN!2 Input 2 Submenu.
47)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 mA as 20 (mA) x 500 = 10000 (entered as 9999)
Press b & c 48) Use b and c buttons to enter IN!2 value.
Press d 49) Display advances to RD!2 Reading 2 Submenu. Press b & c 50) Use b and c buttons to enter RD!2 value.
To show 20 mA as 100 percent enter RD!2 value = 0100
Press d 51) Display flashes STRD stored message momentarily and then advances to ALR1 only, if a change was made, otherwise advances to ALR1 Alarm 1 Menu.
