MDR Requests the instrument model name and firmware code
(16 ASCII chars).
GLP Requests the calibration data record.
The answer string contains:
• GLP status (1 char): represents a 4 bit hexadecimal
encoding.
• 0x01 - pH calibration available
• pH calibration data (if available), which contains:
• the number of calibrated buffers (1 char)
• the offset, with sign and decimal point (7 chars)
• the average of slopes, with sign and decimal
point (7 chars)
• the calibration time, yymmddhhmmss (12 chars)
• buffers information (for each buffer)
• type (1 char): 0 - standard (always 0)
• status (1 char): N (new) - calibrated in last
calibration; O (old) - from an old calibration.
• warnings during calibration (2 chars):
• 00 - no warning
• 01 - clean electrode
• 04 - clean electrode and check buffer
• 05 - contaminated buffer.
• buffer value, with sign and decimal point
(7 chars).
• calibration time, yymmddhhmmss (12 chars).
• electrode condition, with sign (3 chars). The
“-01” code means not calculated.
• electrode response with sign (3 chars). The “-01”
code means not calculated.
PAR Requests the setup parameters setting.
The answer string contains:
• Instrument ID (4 chars)
• Calibration alarm time out (2 chars)
• SETUP information (2 chars): 8 bit hexadecimal
encoding.
• 0x01 - beep ON (else OFF)
• 0x04 - degrees Celsius (else degrees Fahrenheit)
• 0x08 - Offset calibration (else Point calibration)
