INSTRUMENT CALIBRATION PROCEDURES

1 GENERAL GUIDELINES FOR CALIBRATION

For an accurate calibration it is necessary to proceed as follows: a) - The instrument under calibration should be mounted in its case in

order to keep the internal temperature stable.

b) - The ambient temperature should be stable.

Avoid any drift due to air-conditioning or others. c) - The relative humidity should not exceed 70%. d) - The instrument must be in ON condition from 20 minutes at least. e) - Operate, possibly, in an environment with no electromagnetic

disturbances. f) - During calibration, connect to the instrument one input at a time. g) - Before to execute each calibration, be sure that the specific

hardware setting has been made (see "Preliminary hardware

setting" paragraph). For this calibration procedure it is necessary to use calibrators with

the following accuracy and resolution:

ACCURACY

1) For current input:

2) For voltage input : + 0.005% output + 0.001% range + 5 µV

3) For TC input: + 0.005% output + 0.001% range + 5 µV

4) For RTD input:

5) For cold junction compensation: better than 0.1 °C

RESOLUTION

1) For current input: 0.5 µA

2) For voltage input: 100 µV

3) For TC input: 1 µV

4) For RTD input: 10 mΩ

5) For cold junction compensation: better than 0.1 °C

2.4 IN CT / FEEDBACK SELECTION

This instrument can use the "IN CT" input or the "Feedback" input; the two inputs are not contemporarily. The current transformer input allows you to measure and display the current running in a load driven by a time proportional control output during the ON and OFF periods of the output cycle time. By this feature it is also available the "Out failure detection" function (see page 66 in the USER MANUAL). The feedback input is used when the servomotor close loop or the servomotor open loop with valve position indication outputs is required. To select the desired input type, set V301 (see fig. 3) as detailed in the following table:

Input V301.1 V301.2 V301.3 V301.4 IN CT ON OFF ON ON Feedback OFF ON OFF ON

2.5 CALIBRATION MODE SELECTION

To start the calibration procedure, the DIP SWITCH V101, mounted on CPU card, must be set as follows: V101.1 = Not care condition V101.2 = OFF V101.3 = Not care condition V101.4 = ON NOTE: during calibration procedure the serial communication interface will be disabled.

3 CALIBRATION PROCEDURE

3.1 FOREWORD

Calibration parameters are divided in groups. Each group is comprised of two parameters (initial and full scale values) plus a specific calibration check.

Follows a complete list of the "calibrations groups".

1) ñ.I.tc = Main input calibration, TC input

2) ñ.I.CJ = Main input calibration, cold junction

3) ñ.I.rt = Main input calibration, RTD input

4) ñ.I.ñA = Main input calibration, mA input

5) ñ.I.5 = Main input calibration, 5 V input

6) ñ.I.10 = Main input calibration, 10 V input

7) A.I.ñA = Auxiliary input calibration, mA input

8) A.I.5 = Auxiliary input calibration, 5 V input

9) A.I.10 = Auxiliary input calibration, 10 V input

10) In.Ct = Current transformer input calibration

11) FEEd = Feedback input

12) 05.ñA = Out 5 calibration

13) 06.ñA = Out 6 calibration

14) CAL = Default calibration data loading NOTE: Calibration groups from group 7 to group 13 will be shown only when the specific hardware is fitted.

GENERAL NOTE ABOUT CALIBRATION PROCEDURE: During calibration procedure, when the initial or full scale value of a group is selected and the middle display shows "OFF", pushing the FUNC pushbutton the instrument will jump to the next parameter or check without to modify the previous calibration setting. In this way it is possible to recalibrate only the desired input or output. It is also possibe to make a check of one or more calibration group without to remake the specific calibration.

Fig. 4 When it is desired to exit from calibration mode proceed as follows:

1) switch off the instrument;

2) remove the instrument from its case;

3) select the desired operative mode by setting the DIP switch V101 as described in "Operative mode and hardware lock" paragraph reported at page 23 of the USER MANUAL.
