Status 1 (Diode Fault)
2.4 STATUS REGISTERS
2.4.1 Common Status Register
2.4.2 Status 1 Register (Diode Fault)
Status fault bits for open or shorted diode (i.e. Short Fault: D+ shorted to Ground or D-; Open Fault: D+ shorted to V
During fault conditions the temperature reading is 0 °C if unsigned value registers are read or –128.000 °C if signed value registers
are read.
