GOOD LABORATORY PRACTICE (GLP)
GLP is a set of functions that allows storage and retrieval of calibration data and electrode status.
All data regarding pH, EC and NaCl calibration is stored for the user to review when necessary.

For pH calibration,
Mi 180
allows the user to set the number of days (1 to 14) before the next
required calibration. The default setting is OFF (disabled).
The instrument checks the time-out and if the time elapsed, the “CALIBRATION EXPIRED”
message will blink as a reminder.

Note: If the instrument is not calibrated, the “CALIBRATION EXPIRED” message will be
displayed even if the calibration time-out feature is disabled in SETUP menu.
When the reading is stable, the “READY” and “ACCEPT” tags will blink on the LCD.
Press the GLP/ACCEPT key to confirm calibration. The instrument stores the calibration
value and returns to measurement mode.

Notes:
•If the reading is too far from the expected value, the “WRONG” and “SOLUTION”
tags will blink. Calibration cannot be confirmed.
• If the temperature of the buffer is out of the 0.0 – 60.0 °C (32.0 – 140.0 °F)
temperature interval, the “WRONG” “SOLUTION”, “°C” tags and temperature will
be displayed blinking.
• If a new EC calibration is performed, the NaCl calibration is automatically cleared.
Thus, a new NaCl calibration is required.
