FA? Requests the meter to send the calibra-
tion factor of pH. The order of data is
as follows:
1) Month, day and Year
(when the calibration was done)
E.g. "123195" for 31st of Dec. 95
2) Time (when the calibration was done)
E.g. "1259" for 12:59 hh/mm
3) Buffer used when the offset was done
E.g. "0701" for 7.01 pH
4) Offset in mV
E.g. "_00504" for 50.4 mV
"-00504" for 50.4 mV
5) Buffer used when 1st slope was done
E.g. "0401" for 4.01 pH
6) 1st slope in mV
E.g. "000592" for 59.2 mV
7) Buffer used when 2nd slope was done
E.g. "1001" for 10.01 pH
8) 2nd slope in mV
E.g. "000569" for 56.9 mV
9) Temperature
E.g. "_01105" for 110.5°C
"-00099" for -9.9°C
FI? Requests the meter to send the calibra-
tion factor of ION. The order of data is
as follows:
1) Month, day and Year
(when the calibration was done)
E.g. "060395" for 6th of March 95
2) Time (when the calibration was done)
E.g. "1651" for 16:51 hh/mm
2) Buffer used when the offset was done
E.g. "000100" for 10.0ppm
3) Offset in mV
E.g. "000234" for 23.4 mV
4) Buffer used when slope was done
E.g. "010000" for 1000 mV
5) mV measured when the slope was done
E.g. "012345" for 1234.5 mV
6) Temperature
E.g. "_00105" for 10.5°C
"-00099" for -9.9°C
DA? Requests the meter to send the date
E.g. "022896" for 28th Feb. 96
PRE Requests the meter to send the RS232
command prefix
Commands setting parameters:
/BR To set the RS232 baud rate. E.g.
send "/BR0" to set the meter to baud rate of
150
send "/BR1" to set the meter to baud rate of
300
send "/BR2" to set the meter to baud rate of
600
send "/BR3" to set the meter to baud rate of
1200
send "/BR4" to set the meter to baud rate of
2400
/PF To set the RS232 command prefix. E.g.
send "/PF05" to set the command prefix to
05.
For pH 301:
Commands not requiring an answer from
the pH meter:
PHR sets the range to pH
PPM sets the range to ppm
MVR sets the range to mV
OFF is equivalent to pressing the OFF key
Commands requiring an answer:
pH? Causes the meter to send the pH value.
If the reading is out of range "Err 1" is
sent.
pM? Causes the meter to send the ppm value.
If the reading is out of range "Err 5" is
sent.
MV? Causes the meter to send the mV value.
If the reading is out of range "Err 2" is
sent.
TM? Causes the meter to send the tempera-
ture value. If the reading is out of range
"Err 3" is sent.
The meter will send "Err6" if in a different
measurement range.
