④ When you select "4mA-20mA", a window as shown in Fig. 100 appears. Select 4mA or 20mA
adjustments. Here, an example with 4mA adjustment is explained.
Fig.100
Enter the reading of the ammeter currently outputting at "4mA output level" box and click "OK" .
When the reading is sent, the transmitter automatically adjusts the output to 4mA. Verify that the
indicator of the connected ammeter shows 4mA.
If another adjustment is required, repeat the same procedure.
⑤ To execute 20mA adjustment, click the "20mA" tab on the window in Fig. 100. Then execute
adjustment so that the connected ammeter indicator reads 20mA in the same manner as 4mA
adjustment.

⑥ By clicking "Cancel", a message box (Fig. 101) is displayed. Click "OK" .
Here, analog output adjustment with 1 to 5V scale is available. Click "OK" to start the adjustment.
Connect a measuring instrument (reference voltmeter) across both ends of load resistance RL.
⑦ When you select "Other scale", scale input with a voltage value is enabled as shown in Fig.102. When
you enter an analog value (here 1V as an example) equivalent to the output of 4mA for "4mA", the
corresponding value is entered in "20mA" automatically.
