7.1 Error Codes

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. The

possible error codes are listed in Table 40 (page 69).

Table 40 Error Codes, Descriptions and Texts

2 Probe RH measurement error Probe RA meas

3 Probe communication error Probe communication

11 Measurements not available Measurements not available

12 Oscillator fault bit active HW fault 1

13 Analog output quantity invalid Analog output quantity invalid

14 Display quantity invalid Display 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.
