ADAM 4000 Series User’s Manual
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. Calibration
parameters are stored in the ADAM module’s onboard EEPROM.
The ADAM modules come with utility software that supports the
calibration of analog input and analog output. Aside from the
calibration that is carried out through software, the modules incorporate
automatic Zero Calibration and automatic Span Calibration at boot-up
or reset.
8.1 Analog Input Module Calibration
Models: ADAM-4011, 4011D, 4012, 4016, 4017, 4017+, 4018, 4018+,
4018M, 4019+
1. Set modules as initial mode before applying
power to the module
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 that you want to calibrate. You can
do this by using the ADAM utility software. (Please refer to
Appendix D, Utility Software.)
3. Use a precise voltage source to calibrate the module through +IN
and -IN terminals for ADAM-4011, 4011D and 4012. However, for
ADAM-4016, the calibrating voltage should be applied to terminals
Vin+ and Vin- (or Iin+ and Iin-). At last, Vin0+ and Vin0- are used
for calibration in ADAM-4017, 4017+, 4018, 4018+, 4018M, 4019
and 4019+ models.
