Analog Input Module Calibration - Advantech I/O Module 5000 Series User Manual

Analog I/O Modules Calibration
Analog input/output modules are calibrated when you receive them.
However, calibration is sometimes required. No screwdriver is necessary
because calibration is done in software with calibration parameters stored in the
ADAM-5000 analog I/O module's onboard EEPROM.
The ADAM-5000 system comes with the ADAM utility software that
supports calibration of analog input and analog output.
calibration that is carried out through software, the modules incorporate
automatic Zero Calibration and automatic Span Calibration at boot up or
reset.

6.1 Analog input module calibration

Modules: ADAM-5017, 5017H, 5018
1. Apply power to the ADAM-5000 system that the analog input
module is plugged into and let it warm up for about 30 minutes
2. Assure that the module is correctly installed and is properly
configured for the input range you want to calibrate. You can do
this by using the ADAM utility software.
3. Use a precision voltage source to apply a span calibration voltage
to the module's V0+ and V0- terminals. (See Tables 5-2 and 5-3
for reference voltages for each range.)
4. Execute the Zero Calibration command (also called the Offset
Calibration command).
