This column shows a hexadecimal representation of the instrument's 16-bit status
register shown below in Figure C.2. Bit 1 is the least significant bit. The four most
significant bits, Bits 13 to 16 are for Kahn Instruments' service use and so the first
character in any HygroPort I.S. ST display will always read 0.
