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.
Examples
The examples below illustrate how to configure the meter to perform
some typical measurements. Remember to first set R3 and R7 to their full
clockwise position before calibrating the meter.
1. Desired display readings are:
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".
2. Desired display readings are:

respectively, as shown in Table 2).
4mA = "0.000"
20mA = "3.000"
4mA = "0000"
20mA = "8600"

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 pos-
sible 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:
Use DIP-switch setting #13. Apply 4mA and adjust R3 so the display
reads "0000". Apply 20mA and adjust R7 so the display reads "10000".
For these display readings no decimal points are used. Set SW3, SW4,
SW5 and SW6 on switch S2 to OFF.
4. Desired display readings are:
This example is not as straightforward as the previous three. Notice that
12mA is exactly halfway between 4mA and 20mA. If we assume the input
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".
