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 *Err01 Error message configuration. Two different types of failure mode can be set.
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.LIM Limits can be set for shorted and open measurement. Dependent on the main
& *E6.LIM 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).
* To disable the E5/E6 diagnostics the limit must be set to 0 (zero).
Code 55 *% 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 7 possibilities. For
resistivity the default reading is fixed to xx.xx M
Ω
.cm.
Code 57 *USP Automatic checking for compliance with the water purity standard set in USP
(United States Pharmacopeia). For more detailed description see chapter 9.
