calibration error.
Word 0
Bit 06
High/Low bit HL. Indicates whether full scale or zero data point is
being updated:
Bit 6 = 1 - full scale
Bit 6 = 0 - zero data point
Bit 07
Calibration Done bit DN. When set (1), indicates calibration started
and selected channels updated.
Bit 08 (10)
Input Mode bit IM.
Bit 8 = 0 - Use for voltage inputs. Input scaling in mV
Bit 8 = 1 - Use for current inputs. Input scaling in µ A
Bits 09Ć10 (11Ć12) Not used.
Bit 11 (13)
EEPROM OK bit (OK). When set, indicates the calibration data has
been saved.
