8. Good Laboratory Practices (GLP)
The WP-80 keeps a record of the date and time of the last pH asymmetry,
pH slope and Temperature offset calibrations as part of GLP guidelines.
8.1 To recall GLP information on the display
1. Switch the meter on.
2. Select the GLP menu ( →→ F4:Setup →→ F3:GLP).
3. Select F1:Recall from the menu.
4. The instrument model, firmware version number, and instrument serial
number are displayed, along with a prompt describing how to scroll
through the GLP information. For example…
