The transmitter's software provides a variety of self diagnostics information, for example, FLASH and program memory checksum, probe communication status, probe checksum, operation voltage check, and oscillator fault check.
At startup, the transmitter's software checks the factory/user settings checksum, program memory checksum, and oscillator fault status. Other checks are made during runtime. Possible error codes are listed in Table 1.
| Code | Description | Error text |
|---|---|---|
| 1 | Probe T measurement error | Probe T meas |
| 2 | Probe RH measurement error | Probe RA meas |
| 3 | Probe communication error | Probe communication |
| 4 | Probe checksum error | Probe checksum |
| 5 | Probe message form error | Probe message form |
| 6 | Program's flash checksum error | Program code checksum |
| 7 | Current settings checksum error (RAM) | Settings checksum |
| 8 | Factory FLASH not initialized | Factory defaults empty |
| 9 | User FLASH not initialized | User defaults empty |
| 10 | Voltage is too low to operate correctly | Voltage too low |
| 11 | Measurements not available | Measurements not available |
| 12 | Oscillator fault bit active | HW fault 1 |
| 13 | Analog output quantity invalid 1 | Analog output quantity invalid |
| 14 | Display quantity invalid | Display quantity invalid |
| 15 | Invalid relay setting | Relay quantity invalid |
You can view the error text with the errs serial line command. If you are using a transmitter with the optional display, the error code is shown on the display in the following format: ERR:Code-1[.Code-2][.Code-n]. Multiple errors are separated by a period (".") between the error codes.
