Select "4mA to 20mA" from the window shown in Fig. 137 and click the "OK" button to display the
window shown in Fig. 161. Select whether to adjust 4mA or 20mA. This description assumes that
4mA will be adjusted first, followed by 20mA.
Input the value reading currently output on the ammeter and click the "OK" button.
Once the value reading is sent, the converter will automatically make adjustments so that the output
becomes 4mA. Verify that the connected ammeter indicates 4mA.
If another adjustment is necessary, input the value reading of the ammeter into this window again, and
click the "OK" button.
⑤
To adjust 20mA, click the 20mA side of the window shown in Fig. 137, and adjust until the connected
ammeter indicates 20mA, in the same was as with the 4mA adjustment.
⑥
Click the "Cancel" button to exit analog output value adjustment. Click the "OK" button when the
"Adjustment is finished" message box appears as shown in Fig. 138.
⑦
Click the "Cancel" button to halt adjustment in progress, and follow the instructions that appear.
⑧
When "Other scale" is selected in the window shown in Fig. 136, another scale can be inputted as
shown in Fig. 139. When an analog value equivalent to 4mA output is inputted into the first field (the
4mA side), then a corresponding value is automatically inputted into the second field (the 20mA side).
Analog output can be adjusted here for the 1 to 5V scale.
Click the "OK" button to start the adjustment. Connect a meter (standard voltmeter) to both ends of the
load resistance R
L

Click here and select
which to adjust.
There is no need to input
a value into the second
field. Inputting into the
first field causes a value
to be inputted into the
second field as well.
