When the resolution is set to 1/12,000, the 0 to 10-V range corresponds to
hexadecimal values 0000 to 2EE0 (0 to 12,000). The entire data range is
FDA8 to 3138 (−600 to 12,600).
A negative voltage is expressed as a two’s complement.
The following diagram shows conversion values for 1/6,000 resolution.
0 to 5 V Input
When the resolution is set to 1/6,000, the 0 to 5-V range corresponds to hexa-
decimal values 0000 to 1770 (0 to 6,000). The entire data range is FED4 to
189C (−300 to 6,300).
When the resolution is set to 1/12,000, the 0 to 5-V range corresponds to
hexadecimal values 0000 to 2EE0 (0 to 12,000). The entire data range is
FDA8 to 3138 (−600 to 12,600).
A negative voltage is expressed as a two’s complement.
The following diagram shows conversion values for 1/6,000 resolution.
1 to 5 V Input
When the resolution is set to 1/6,000, the 1 to 5-V range corresponds to hexa-
decimal values 0000 to 1770 (0 to 6,000). The entire data range is FED4 to
189C (−300 to 6,300).
When the resolution is set to 1/12,000, the 1 to 5-V range corresponds to
hexadecimal values 0000 to 2EE0 (0 to 12,000). The entire data range is
FDA8 to 3138 (−600 to 12,600).
Inputs between 0.8 and 1 V are expressed as two’s complements. If the input
falls below 0.8 V, open-circuit detection will activate and converted data will be
8000.
