Table C.1 Status Register Flags - Kahn HygroPort I.S. User Manual

HygroPort I.S. User's Manual
Table C.1 shows the status flags associated with each Bit of the status register. If a
status f l lag is set high then the associated condition exists. If it is set low, then that
condition does not exist.
Status Register
Bit in Hex
0x0002 = BIT 2
0x0004= BIT 3
0x0008 = BIT 4
0x0010 = BIT 5
0x0020 = BIT 6
0x0040 = BIT 7
0x0080 = BIT 8
0x0100 = BIT 9
0x0200 = BIT 10
0x0800 = BIT 12
For the example given in Figure C.1, from Table C.1, Hex 28 translates, reading from
right to left, as Bit 4 set (External sensor error) and Bit 6 set ( Measurement in
progress). Therefore, at the time that these log points were taken, the external sensor
was out of range and the internal dewpoint was not stable.
