pH ARC Sensors Modbus RTU Programmer’s Manual (EPHUM011)

The different functionalities of product calibration (CP6) are accessible through the following sensor commands:

Initial measurement

Assignment

Cancel

Restore standard calibration

Restore product calibration

All commands are executed by writing a command value to the register 5340 except for assignment where the calibration value is written to register 5322 (see below).

Definition of the commands for product calibration
The commands for register 5340 are defined as follows:
Code Hex			Definition of commands
0x01			Perform initial measurement
0x02			Cancel an active product calibration
0x03			Restore a standard calibration from an active product calibration
0x04			Restore a product calibration from an active standard calibration

2.7.3.2.1Product calibration: Initial measurement

Upon process sample collection for laboratory analysis the command for initial measurement is sent to the sensor.

This is achieved by writing the command 0x01 to register 5340 which performs the initial measurement and stores the corresponding measurement values in the sensor.

Command: CP6: Initial measurement			Modbus address: 5340		Length: 2	Type: 16	Write
Parameter:	Command
Format:	Hex
Value:	0x01

Figure 2.7.3.2.1.1: Example to start the product calibration procedure. Writing the command code 0x01 (initial measurement) to the CP6 command register 5340.

After successful initial measurement the corresponding calibration status (register 5318, figure 2.7.4.2.1) is “CP6 initial measurement”(0x08000000) (see figure 2.7.4.1.1).

The sensor continues measuring using the prior standard calibration.
