7.5.5 Pneumatic test
The pneumatic test tests the measurement precision of the measuring head.
It says nothing about the long-term impermeability of the system.
To perform the pneumatic test, you require the test resource, OxiTop
®
PT
(WTW order number 209 334).
The user interface of the controller guides you through the test:
- Set Cal date
This menu item only appears if
the controller is in the
BOD Standard operating mode,
GLP is switched on and the test
is finished.
- Stop :
Return to the curve display. The
Cal test is considered as not
performed.
The controller sets a new test
date in the measuring head. The
controller calculates the new
test date from the current date +
the check interval set up (see
section 7.4.5 GLP -
CALIBRATION
INTERVAL
(- C
ALINTERVAL
), page
43).
The controller displays the set-
ting of the calibration date.
If the date was not set successfully (e.g. because the control-
ler was not held to - or not held close enough to - the measur-
ing head):
Repeat the procedure using
<RUN/ENTER>
.
Then continue as described
above.
