Hanna Instruments HI 98180 Instruction Manual page 54

• 05 - ISE range
• Meter status (2 chars of status byte): represents a 8 bit
hexadecimal encoding.
• 0x10 - temperature probe is connected
• 0x01 - new GLP data available
• 0x02 - new SETUP parameter
• 0x04 - out of calibration range
• 0x08 - the meter is in autoend point mode
• Reading status (2 chars): R - in range, O - over range, U -
under range. First character corresponds to the primary
reading. Second character corresponds to mV reading.
• Primary reading (corresponding to the selected range) -
11 ASCII chars, including sign and decimal point and
exponent.
• 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 ºC.
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
• 0x02 - Rel mV calibration available
• 0x04 - ISE calibration available
• pH calibration data (if available), which contains:
• the number of calibrated buffers (1 char)
• the ion charge, with sign (2 chars)
• 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;
• warnings during calibration (2 chars): 00 - no
warning, 04 - Clean Electrode warning.
O (old) - from an old calibration.
