GLP

11. 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.

1. Press RANGE/



to select mode (PH, CONDUCTIVITy, or TDS).

2. From the measurement screen, press GLP/ACCEPT to view

GLP data.

3. Use the



keys to navigate calibration data displayed on

the third LCD line.

pH Data:

offset, slope, pH calibration solutions, time, date,

calibration expiration time (if enabled in SETUP).

EC/TDS Data:

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).

4. Press ESC or GLP/ACCEPT to return to measurement mode.

If the probe 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.
