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

The here performed assignment was successful. The sensor is running using a valid product calibration.

Figure 2.7.4.2.3.1: Example to read the calibration status of CP6 after having performed a cancel command at CP6.

The status reports no messages. The last successful calibration at CP6 has been performed at pH 4.5.

The sensor is running on a valid standard calibration and no product calibration is stored.

2.7.4.2.4Product calibration: Restore standard calibration

Figure 2.7.4.2.4.1: Example to read the calibration status of CP6 after having restored the standard calibration from an active product calibration (CP6).

The status says: “CP6 assigned”(0x10000000). The last successful calibration at CP6 has been performed at pH 4.5.

The sensor is running on a valid standard calibration but a valid product calibration is still available in the sensor.

2.7.4.2.5Product calibration: Restore product calibration

Figure 2.7.4.2.5.1: Example to read the calibration status of CP6 after having restored an available product calibration (CP6) from an active standard calibration (CP1 / CP2).

The status says: “CP6: active”(0x04000000) and “CP6: assigned”(0x10000000). The last successful calibration corresponding to the here performed assignment has been performed at pH 4.5.

The sensor is running on a valid product calibration again.
