2.7.9 Special Commands for Calibration with VISICAL

The VISICAL calibration device allows calibration of pH ARC Sensors at CP1 or CP2. The pH ARC Sensor’s associated calibration parameters for CP1 and CP2 are those predefined and stored in corresponding registers of the sensor.

Register 5164 defines the pH value for CP1 and register 5196 defines the pH value for CP2, which are only valid for use with VISICAL. The same calibration limits for the pH value are used as for standard calibration at CP1 and CP2 (register 5152 and 5184 respectively).

Attention:

It is not possible to perform a product calibration using VISICAL.

Physical unit is fixed to pH by definition.

Start	Number of	Reg1 / Reg2	Modbus	Read	Write
register	registers		function code	access	access
5180	2	pH value at CP1 (default: pH 4.00)	3, 4, 16	U/A/S	S
5212	2	pH value at CP2 (default: pH 7.00)	3, 4, 16	U/A/S	S

Figure 2.7.9.1: Definition of register 5180 for CP1 and 5212 for CP2.

Command: VISICAL CP1			Modbus address: 5180		Length: 2	Type: 3	Read
Parameter:	Value [pH]
Format:	Float
Value:	4.00

Figure 2.7.9.2: Example to read the pH value valid for CP1. It is 4.00. Accordingly, the next time when a calibration is started using VISICAL at LOW, a calibration with manual selection is performed, using the calibration standard at pH 4. The operator has to make sure that - within the selected set of calibration standards - a standard at pH 4 is selected for manual selection.

Command: VISICAL CP2			Modbus address: 5212		Length: 2	Type: 16	Write
Parameter:	Value [pH]
Format:	Float
Value:	7.00
Figure 2.7.9.3:	Example to set the pH	value valid for CP2.

Command: VISICAL CP2			Modbus address: 5212		Length: 2	Type: 3	Read
Parameter:	Value [pH]
Format:	Float
Value:	7.00

Figure 2.7.9.4: Example to read the pH value valid for CP2. It is 7.00. Accordingly, the next time when a calibration is started using VISICAL at HIGH, a calibration with manual selection is performed, using the calibration standard at pH 7. The operator has to make sure that - within the selected set of calibration standards - a standard at pH 7 is selected for manual selection.
