4.11.1. How to calibrate the analog output

Description
 The calibration is performed so as to obtain 4mA and 20mA when the analog signal (4-20mA DC) output is 0% and 100%,
respectively.
 Connect an ammeter to Iout terminals as shown below. In the CURRENT CALIBRATION mode, select 4mA or 20mA, and operate the
