Error Codes
Example: 0100
Represents erro bit 8 set and the Pressure Output Limited
Notes:
Bit 0 : This should not appear if the part has been calibrated
Bits 1 thru 7 : indicate computational error when compensated
Bit 8: indicates that the pressure applied to the part exceeds the
range of the part and is limit to either the high or low limit
{null}
Null Response
No response from the part. In the event of a serial number
mismatch the part will not respond (to avoid buss contention.)

The error codes are bits packed within a double byte.
The four character string is an ascii hex expression.
The error code bits are:
Bit 0 : Part not factory compensated
Bit 1 : Tdex Overflow
Bit 2 : Tdex Over-range
Bit 3 : Pdex Overflow
Bit 4 : Pdex Over-range
Bit 5 : PWL Overflow
Bit 6 : Scale Overflow
Bit 7 : High Resolution Overflow
Bit 8 : Pressure Output Limited to Specific Value
Bits 9 through 15 : Reserved
