CALIBRATION
The CD600 Plus is factory calibrated according to procedures complying with the ISO9000
Standards. If a new calibration is required, it can be easily done through the CONF600 Plus.
First, check the CD600 Plus identification address. Press the <ACK> key at the front panel of the
CD600 Plus and hold for a few seconds until the display message changes. Then press the <ACK>
and the <DSP> keys together, the panel display will show the Identification Address of the CD600
Plus. The user can change the numerical value of the display with the keys <Δ> or <∇>. The value
“1” means that the controller accepts communication with the Hand-Held Terminal only. Values from
“2” up to “30” are the programmed controller addresses in the serial communication network. Click
the <LP> key to return to normal operation.
The table below displays the input and output parameters available for the CD600 Plus calibration.

Analog Input
The analog inputs are 0-5V voltage inputs. To convert the voltage inputs into 0-20mA current inputs,
connect the 250 Ω shunt resistor to the terminal.
To calibrate an analog input J (J = AI1 to AI8), follow these steps:
a) Check if the input to be calibrated will work as current or voltage input. If it will work as a current
input, it is recommended to use the same shunt resistor that will be used during operation;
b) Connect the voltage or current generator with indicator to the terminals corresponding to the J
input;
c) Select the output from the J analog input block to be displayed on the controller. Be sure that the
square root extraction and linearization function are not activated;
d) Connect the computer to the controller through the ICS2.0-1 interface;
e) Go to the Tool menu and click Calibration to open the Calibration dialog box. Select the device
address using the Identification Address value and click the button Look to locate the device:
