Description
Bit 00 Input select bit. Indicates input channel 0 being calibrated.
Bit 01 Input select bit. Indicates input channel 1 being calibrated.
Bit 02 Input select bit. Indicates input channel 2 being calibrated.
Bit 03 Input select bit. Indicates input channel 3 being calibrated.
Bit 04 Output select bit. Indicates output channel 0 being calibrated.
Bit 05 Output select bit. Indicates output channel 1 being calibrated.
Word 0
Bit 06
High/low bit HL. Indicates whether full scale or zero data point is being
updated:
Bit 06 = 1 - full scale
Bit 06 = 0 - zero data point
Bit 07
Execute Bit. EX. When set (1), starts calibration and updates the
selected channels.
Bit 08 (10)
Input Mode Bit IM.
Bit 08 (10) = 0 - Use for voltage inputs. Input scaling in mV
Bit 08 (10) = 1 - Use for current inputs. Input scaling in µA
Bits 910 (1112) Not used
Bit 11 (13)
EEPROM write bit OK. When set (1), requests the current calibration
data be saved.
Bits 1215 (1417) Calibration mode bits. Set to 1100 to select a calibration sequence.
Word 1 Bits 0015 (0017)
Output Channel 0 Calibration Data - user entered calibration data
when EX = 0 (bit 07 in word 0), scaled and corrected output data when
DN bit (bit 07 in BTR) = 1.
Word 2 Bits 0015 (0017)
Output Channel 1 Calibration Data - user entered calibration data
when EX = 0 (bit 07 in word 0), scaled and corrected output data when
DN bit (bit 07 in BTR) = 1.
