• 0x10: temperature probe connection
• 0x20: DO measure unit (0 = %, 1= mg/L)
• 0x01: new GLP GLP GLP GLP GLP data available
• 0x02: new setup parameter
• 0x04: out of calibration range
• 0x08: the meter is in autoend mode;

mode 25
• DO reading, including sign and decimal point (8 chars)
• temperature, including sign and decimal point (8chars)
• pressure value, including sign and decimal point, always
in mmHg (11 chars)
• OUR/SOUR reading, including sign and decimal point
(sent only if in OUR/SOUR measure mode) (8 chars)
• OUR/SOUR counter (sent only if in OUR/SOUR measure
mode) (4 chars)
• The following values are sent only for mode 25

(6 chars)
MDR Requests the instrument model name and firmware code (16 ASCII chars).
GLP Requests the calibration data record.
The answer string contains:
• the number of calibrated buffers (1 char)
• calibrated buffer unit (0 = %, 1 = mg/L) (1 char)
• buffer value including sign and decimal point (6 chars)
• calibrated buffer unit (0 = %, 1 = mg/L) (this value is sent only
if there is a 2 point calibration) (1 char)
