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.
Passcodes can be set on any or all of the access levels, to restrict access to
the instrument configuration.
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.
Limits can be set for shorted and open measurement. Dependent on the main
parameter chosen in code 01, the EXA will ask for a resistivity or conductivity
value to be set (value to be set is the uncompensated conductivity/resistivity
value).
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.
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 7 possibilities.
For resistivity the default reading is fixed to xx.xx MΩ·cm.
Automatic checking for compliance with the water purity standard set in USP
(United States Pharmacopeia). For more detailed description see chapter 9.
