APPENDIX B
Note 4 - Output 1 & 2 Min/Max
The register type and divider for Output 1 Min and Output 1 Max are inherited from the parameters
selected in Output 1 Type. For example, if Water Activity is selected, then the type is UInt16, and the
divider is 100 as per the register map entry.
The register type and divider for Output 2 Min and Output 2 Max are inherited from the parameters
selected in Output 2 Type.
Register TYPE_A (Status Register)
Bit Flag
0 Output 1 under range
1 Output 1 over range
2 Output 2 under range
3 Output 2 over range
4 Thermistor open-circuit
5 Thermistor short-circuit
6 RH element open-circuit
7 RH element short-circuit
8 Sensor communications error
9 Input volts too low
10 Logic volts too low
11 Temperature out-of-range
12 RH out-of-range
13 Not Used
14 Customer extended access
15 Diagnostic mode enabled
One or more bits are set to '1' to indicate an error or alternative mode of operation.
Register TYPE_B (Serial Number Registers)
Two consecutive 16-bit registers form a 32-bit unsigned integer, X, that stores the serial number. The
displayed serial number has the format HH-DDDDDD, where H is a hex digit & D is a decimal digit.
HH = (X & 0x0FF00000) >> 20 (displayed as 2 hexadecimal digits)
DDDDDD = X & 0x000FFFFF (displayed as a decimal number)
Example: If REG_PROBE_SERIAL_HI = 0x0AA5 and REG_PROBE_SERIAL_LO = 0x464E, then the
probe serial number is displayed as "AA-345678"
