Instruction Manual

The answer string for each record contains the number of records if ALL

data is requested - 3 chars

• The logged mode (2 chars):

• 06 - EC range

• 07 - TDS range

• 08 - NaCl range

• Reading status (1 char): R, O, U

• Calculated reading, with sign and decimal point

(7 chars)

• Temperature reading, with sign and two decimal

points (8 chars)

• EC reading status (1 char): R, O, U - for TDS,

NaCl range

• Unit of the reading - for TDS, NaCl range (1 char)

• The EC reading, with sign and decimal point - for

TDS, NaCl range (7 chars)

• The logged time, yymmddhhmmss (12 chars)

• The calibration offset, with sign and decimal point

(7 chars)

• The calibration slope, with sign and decimal point

(7 chars) (Kcell for EC and TDS range and the slope

for NaCl).

• Temperature probe presence (1 char)

• Temperature compensation coefficient (5 chars)

• Temperature reference value (5 chars)

• Temperature compensation mode (1 char)

Notes: • “Err8” is sent if the instrument is not in measurement mode.

• “Err6” is sent if the requested range is not available.

• “Err4” is sent if the requested set parameter is not available.

• “Err3” is sent if the Log on demand is empty.

• “Err9” is sent if the battery power is less than 30%.

• Invalid commands will be ignored.
