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. Possible
error codes are listed in
Table 52 Error codes, descriptions, and texts
Code
1
Probe T measurement error
2
Probe RH measurement error
3
Probe communication error
4
Probe checksum error
5
Probe message form error
6
Program's flash checksum error
7

(RAM)
8

Measurement parameters are referred to as 'quantities' in the transmitter's software.
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.
