2.7.4Reading the Calibration Status

2.7.4.1Reading the Calibration Status of CP1 and CP2

A standard calibration is not always successful. In order to analyze what has gone wrong, two different calibration status registers can be read:

Register 5158 for CP1

Register 5190 for CP2

Note

Registers 5158 and 5190 contain the same information!

Bit #	Hex value	Definition
0 (LSB)	0x00000001	CP1: difference between CP1 and CP2 < pH 1.0
1	0x00000002	CP1: no matching calibration standard
2	0x00000004	CP1: actual temperature reading is too low
3	0x00000008	CP1: actual temperature reading is too high
4	0x00000010	CP1: temperature reading during calibration is not stable
5	0x00000020	CP1: offset a pH 7 is too low or slope is too low
6	0x00000040	CP1: offset a pH 7 is too high or slope is too high
7	0x00000080	CP1: pH reading during calibration is not stable
8	0x00000100	CP2: difference between CP2 and CP1 < pH 1.0
9	0x00000200	CP2: no matching calibration standard
10	0x00000400	CP2: actual temperature reading is too low
11	0x00000800	CP2: actual temperature reading is too high
12	0x00001000	CP2: temperature reading during calibration is not stable
13	0x00002000	CP2: offset a pH 7 is too low or slope is too low
14	0x00004000	CP2: offset a pH 7 is too high or slope is too high
15	0x00008000	CP2: pH reading during calibration is not stable
…		not available
24	0x01000000	CP6: out of calibration range
25	0x02000000	CP6: out of range
26	0x04000000	CP6: active
27	0x08000000	CP6: initial measurement
28	0x10000000	CP6: assigned
		not available
30	0x40000000	CP2: incorrect measurement unit
31	0x80000000	CP1: incorrect measurement unit
