ACE
• Secondary reading (only when primary reading is not mV) - 7 ASCII chars, including
sign and decimal point.
• Temperature reading - 7 ASCII chars, with sign and two decimal points, always in °C.
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, 1 - custom
• status (1 char): N (new) - calibrated in last calibration; O (old) - from an
old calibration
• warnings during calibration (2 chars): 00 - no warning, 04 - “Clean
Electrode“ warning
• buffer value, with sign and decimal point and exponent (11 chars)
• calibration time, yymmddhhmmss (12 chars)
• electrode condition, 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 for pH (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)
