GLP
The GLP (Good Laboratory Practice) set of rules presents particular requirements
concerning test resource monitoring for the measuring systems implemented
(quality assurance).
The following points must be fulfilled to comply with the requirements of GLP,:
1. Documentation of the calibration intervals.
2. Reporting of the calibrations:
Identification no. of the measuring head/controller
Date and signature of the operator.
3. Determination of the calibration frequency and instructions for the
performance:
The frequency depends on the operating conditions and the data of the test plan.
The OxiTop
® Control system supports these standards using an add-on GLP mode:
This mode inhibits measuring if the calibrating interval is exceeded.
As a result of these restrictions, the GLP mode effects a standardization of the
calibrating and measuring conditions that are indispensable for working from the
aspect of quality assurance.
Switch the GLP function on or off (only in the standard BOD operating mode):

GLP - calibrating interval (“Calinterval”)
Set the time period (1 to 36 months) here. When it expires, the instrument registers
that the next test resource monitoring of the measuring heads is due. After the
calibrating interval expires, measuring is blocked until the calibration is performed or
the GLP setting is set to “Off“.
If the end of the calibrating interval set up lies within the measuring time of a
measurement to be started, this measurement cannot be started.
