tested with meters supporting current output (4 - 20mA) and voltage output (0 - 10 VDC) and 2N SmartCOM PRO ETH with firmware SCE_1.12.0.12.24 supporting AMS features.
Before measurement calibrate 2N SmartCOM PRO ETH inputs - Input circuit calibration
Make sure that the 2N SmartCOM PRO ETH jumpers are set as shown in figure

A) Measuring analogue value on input
at^scams="ENABLE",1 - enable AMS functionality.
AT^SCAMS="DEV_ADD",128,"AIN_DIN","1/ADC/CAL","1M" - calibrated value will be store to memory (range 0 - 100) input 1
AT^SCAMS="DEV_ADD",128,"AIN_DIN","2/ADC/ABS","1M" - output from A/D converter will be stored to memory (range 0 - 1023) input 2
Possible time intervals: - "1M", "2M", "3M", "4M", "5M", "6M", "10M", "12M", "15M", "20M", "30M", "1H", "2H", "3H", "4H", "6H", "8H", "12H", "1D"
