4. If necessary, select the appropriate decimal point by setting either
SW3, SW4, SW5, or SW6 of S2 to ON (DP1, DP2, DP3, or DP4,
respectively, as shown in Table 2).
NOTE: Please keep in mind that the transmitter's 4mA and 20mA output
accuracy may affect display readings which are at, or very close to, the
high and low extremes of the selected range. See Example #2 below and
Technical Note 1 for more information.
Use DIP-switch setting #11. Apply 4mA and adjust R3 so the display
reads "0000". Apply 20mA and adjust R7 so the display reads "8600".
If the transmitter's full-scale output is less than 20.0mA, it may not be
possible to adjust R7 for a reading of "8600" with setting #11. If this
occurs, select setting #12 and re-calibrate both R3 and R7 to obtain
"0000" and "8600". Note that for these display readings no decimal
points are used. Set SW3, SW4, SW5 and SW6 on switch S2 to OFF.
3. Desired display readings are:
S1
S2

Use DIP-switch setting #3 and enable decimal point DP2 by placing
SW4 of switch S2 to ON. Apply 4mA and adjust R3 so the display reads
"0.000". Apply 20mA and adjust R7 so the display reads "3.000".

This example is not as straightforward as the previous three. Notice that
12mA is exactly halfway between 4mA and 20mA. If we assume the in-
put could go up to 20mA, the display reading would then be 2 x .2500 or
".5000". From the table, we can select DIP-switch setting #7 and enable
DP1 via SW3 of switch S2. Apply 4mA and adjust R3 so the display reads
".0000". Apply 12mA and adjust R7 so the display reads ".2500".
