13. GLP
Good Laboratory Practice (GLP) allows the user to store and recall calibration data.
Correlating readings with specific calibrations ensures uniformity and consistency.
Calibration data is stored automatically after a successful calibration. Saving a new
EC calibration automatically clears the existing %NaCl calibration.

Use the
keys to scroll through the calibration data displayed on the third LCD line
y
Press ESC or GLP/ACCEPT to return to measurement mode.
GLP information is included with every data log.
pH INFORMATION
pH calibration data displayed on the third LCD line: offset, slope, pH calibration solutions,
time, date, calibration expiration time (if enabled in SETUP).
EC/TDS INFORMATION
EC calibration data displayed on the third LCD line: cell factor (C.F.), offset, EC standard
solution, temperature coefficient (T.Coef.), temperature reference (T.Ref.), time, date,
calibration expiration time (if enabled in SETUP).
NaCl% INFORMATION
Salinity calibration data displayed on the third LCD line: cell factor (C.F.), coefficient,
salinity standard solution, time, date, calibration expiration time (if enabled in SETUP)
If the instrument has not been calibrated or calibration has been deleted, the blinking
“NO CAL” message is displayed in GLP.
If calibration expiration time is disabled, “EXP WARN DIS” is displayed.
