-Overrage for the measured value: R-in range, O-over range, U-under range.
-Measured value (7 chars): for the pH meter log this is the measured pH value; for
the titrator log this is the concentration value
-Temperature reading, with two decimal points (7 chars) (only for pH meter log)
-Calibration offset (7 chars) (only for pH meter log)
-Calibration slope (7 chars) (only for pH meter log)
-Concentration unit (1 char) (only for titrator log): 0=mg/L, 1=meq/L
-Acidity type (1 char) (only for titrator log): 0=Total LR, 1=Total HR, 2=Strong LR,
3=Strong HR
-Logged time (12 chars):
yymmddhhmmss
-Temperature probe presence (1 char)
-Checksum (2 chars)
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
-Invalid commands will be ignored.
PAR

NSLx
Requests the number of logged samples (4 chars).
The command parameter (1 char):
-P-request for pH meter
-T-request for titrator
LODPxxx
Requests the xxxth pH record logged data
LODTxxx
Requests the xxxth titrator record logged data
LODPALL
Requests all the stored records from the pH meter log
