1. Apply power to the module and let it warm up for about 30 minutes.
2. Make sure that the module is correctly installed and is properly
configured for the input range you want to calibrate. You can use
the ADAM utility software to help in this.
3. Connect the correct reference self resistance between the screw
terminals of the ADAM-5013 as shown in the following wiring
diagram. Table 4-2 below shows the correct values of the span and
zero calibration resistances to be connected. Reference resistances
used can be from a precision resistance decade box or from discrete
resistors with the values 60, 140, 200 and 440 ohms.
4. First, with the correct zero (offset) calibration resistance connected
as shown above, issue a Zero Calibration command to the module
using the Calibrate option in the ADAM utility software.
5. Second, with the correct span resistance connected as shown
above, issue a Span Calibration command to the module using the
Calibrate option in the ADAM utility software. Note that the
module zero calibration must be completed prior to the span
calibration.
