5-18 Parameter setting
5-3-5. User interface
Code 50 *RET. When Auto return is enabled, the transmitter reverts to the measuring mode
from anywhere in the configuration menus, when no button is pressed during
the set time interval of 10 minutes.
Code 52 *PASS Passcodes can be set on any or all of the access levels, to restrict access to
the instrument configuration.
Code 53 *Err.05 to Error message configuration. Two different types of failure mode can be set.
*Err.08 Hard fail gives a steady FAIL flag in the display. A fail signal is transmitted on
the mA output when enabled in code 32.
Soft fail gives a flashing FAIL flag in the display. A good example is the dry
sensor for a soft fail.
Code 54 *E5.LS Limits can be set for shorted and open measurement. E5 (High) is default set
*E6.LIM to 3 S and must be in the range of 0.10 S to 9.99 S. E6 (Low) is default set to
5 μS and must be in the range of 0.00 μS to 99.9 μS.
Code 55 *% Linear weight percentage. For some applications the measured parameter
values may be (more or less) linear to concentration. For such applications it
is not needed to enter an output table, but 0 and 100% concentration values
directly can be set.
Code 56 *DISP. The display resolution is default set to autoranging for conductivity reading. If a
fixed display reading is needed, a choice can be made out of 5 possibilities.
