Figure 36 Current Datalog File Display
This column shows a hexadecimal representation of the instrument’s 16-bit status
register shown below in Figure 36. Bit 1 is the least significant bit. The four most
significant bits 13 to 16 are for Michell Instruments’ service use and so the first character
in any MDM300 I.S. ST display will always read 0.

Each of the error bits set high (1) represents a specific status or error condition. In this
example, bits 4 and 6 are set high indicating that two (status) conditions exist.
