GLP (4)
Refer to Appendix for more information. This option determines whether GLP is on
or off in terms of printing and reporting the results; the calibration interval for GLP,
however, is always on and can be done automatically at pre-defined time intervals
(always on, daily, weekly, monthly, quarterly). If GLP is on, the results are printed
automatically after calibration; they can also be printed on demand using Print (F2)
on the System page. Note that the GLP print out will show the date for when the full
calibration was done (“Calibrated”), and that this can be different to the date of
instrument operation (“Date”); this is shown on the example below. If the date is the
same, “Calibrated” shows the time that it was done instead.
Press “More…” (F3) on the system page to view the GLP results on the instrument
display.
