CAUTION
If danger is expected by canceling the error setting, do not turn the error setting to OFF.
If you use it with it turned o, it may cause danger.
NOTE
The “Impedance (pH/ORP) too high/too low” and “ Impedance (ref) too high/too low” alarms are
displayed in the Error setting. In general, for a pH sensor, “Impedance (pH/ORP)” is of “glass
elewakctrode.” “ Impedance (ref)” is of the reference electrode.
The “Impedance (pH/ORP) too high/too low” and “ Impedance (ref) too high/ too low” errors apply
to sensors with liquid earth. Sensors with liquid earth include PH8EFP, PH8ERP, PH8EHP.
For sensors not equipped with liquid earth, these alarms should all be set to O. These sensors
include HA405, HA406, DPA406, DPA405, DPAS405, HF405, HA485, DPA485.
For measuring a solution with low conductivity such as pure water pH measurement, set the “
Impedance (ref) too high” error to O.
For details of errors, refer to MODBUS technical information TI 12A01G01-62EN
