List of Serial Command
●
Use <CR><LF> as the terminator for serial communication commands.
●
All the commands except the online/offline command are valid only in the Online mode.
(An error message is returned in the Offline mode.)
●
the pH meter returns a response to any operation made in the following format.
OK<CR><LF>
●
If the pH meter does not accept the operation, it returns an error message in the following
format.
ER,n<CR><LF>
n= 1: When a non-existent command is input.
2: When a timing command is input to which the meter cannot respond.
3: When the numerical value in the command is out of the setting range.
●
When logging off the PC by pressing the ON/OFF key in the Online mode, the PC com-
pulsorily falls into the Offline mode.
●
Only the online/offline commands, interruption of potential tracing, the measurement
value request command, and the data IN specification command are effective when the
pH meter is performing various measurement (while HOLD lamp blinks.)
●
Mode specification commands (such as CPH,CMV,CIO,CCO,COH,CSA) and measure-
ment start command (CMS) are effective only when the main screen and the specified
channel are matched.
●
If the present measurement mode and the channel are not matched, an error message
(incorrect operation) is responded when calibration starts.
●
To return to the Measurement screen after the calibration is complete, transmit the mode
specification command for the present calibration or the mode specification command
that exists in the specified channel.
●
When only “.”is input for the item to which a numeral with decimal point can be input, it
is regarded as “0.0”.
●
When calibration is in the HOLD condition, confirm that no alarm is output by perform-
ing the alarm inquiry
●
When the measurement value request command is output, the data showing the HOLD
condition may return from Measurement (2) to Instant value (0). In such a case, the elec-
trode instability error (ERR 03) has occurred.
●
The alarm contents cannot be cleared by the serial command. The alarm can be cleared
only by checking the countermeasures, pressing the NAVI key in the Offline mode. Some
alarms output during calibration may be cleared by performing the calibration again and
the calibration ends successfully.
●
Some commands are accepted or refused depending on the models.
