Examples
+24V
Use DIP-switch setting #1 and enable decimal point DP2 via SW6.
Apply 4mA and adjust R3 so the display reads "0.00". Apply 20mA and
adjust R7 so the display reads "2.00".
Use DIP-switch setting #4. Apply 12mA and adjust R3 so the display
reads "000". Apply 20mA and adjust R7 so the display reads "100".
Apply 4mA and the display should read "–100". For these display read-
ings, no decimal points are used. Set SW5, SW6 and SW7 to OFF.
4mA ="0.00"
4mA = "–100"
This example is not as straightforward as the previous two. Notice that
12mA is exactly halfway between 4mA and 20mA. If we assume the
input could go up to 20mA, the display reading would be: 2 x .250 or
".500". From the table, we can select DIP-switch setting #2 and enable
DP1 via SW5. Apply 4mA and adjust R3 so the display reads ".000".
Apply 12mA and adjust R7 so the display reads ".250".
