A window like the one shown in Fig. 107 appears. Select either "4-20mA" scale or "Other scale" for
Analog 1 trim, and click on "OK"
.
If you want to work with the 4-20mA scale, trimming is made by steps
④
through
⑦
by inserting a reference
ammeter in series with the output loop of Analog Output .
On other scale, insert a load resistor (R
L
=250Ω is inserted and the 1-5V scale across this resistor is used
for adjustment) and trimming is made according to steps
⑧
through
⑫
.

At the window in Fig. 107, select "4mA-20mA" and click on "OK"
. A window as shown in Fig. 08 then
appears, readying for selecting the 4mA or 20mA trim. Make the 4mA trim here, followed by the 20mA
trim. Enter the ammeter reading of the current output and click on "OK" button.
As the reading is transferred, the transmitter automatically adjusts the output to 4mA. Verify that the
reading of the ammeter connected registers 4mA.
If it proves that readjustment is required, enter the ammeter reading again at this message box and click
on "OK"
.
⑤
To trim the 20mA, click on the 20mA at the message box shown in Fig. 08. Similar to the 4mA trim,
make an adjustment until the ammeter connected reads 20mA.
