• Reading status (2 chars): R - in range, O - over

range, U - under range. First character corresponds

to the appropriate range reading. Second character

corresponds to mV reading.

• Primary reading (corresponding to the selected range)

- 7 ASCII chars, including sign and decimal point.

• 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 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

(7 chars).

• calibration time, yymmddhhmmss (12 chars).

• electrode condition, with sign (3 chars). The “-01”

code means not calculated.
