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.
