Cal test
The Cal test is used to test the sealing of the system measuring head - rubber
sleeve - sample bottle and the operability of the systems OxiTop
® Control.
In the standard BOD operating mode with the “GLP ON” setting, the controller
indicates when the next Cal test is due after each set up calibration interval (see the
chapter “GLP/Tools - GLP”),.
To perform the test, you need the WTW test resource, OxiTop
® PM, order number
