5 ADAM-5000 Series User Manual

Chapter 1 Overview

ADAM-5013 RTD Input Resistance Calibration

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 2 below shows the

correct values of the span and zero calibration resistances to be connected. Ref-

erence resistances used can be from a precision resistance decade box or from

discrete resistors with the values 60, 140, 200 and 440 ohms.

Figure 1.3 Applying Calibration Resistance

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.

Note! If the above procedure is ineffective, the user must first issue an RTD

Self Calibration command $aaSi2 to the module and then complete

steps 4 and 5 after self calibration is complete.
