trum depending on their composition and food supply. With the aid of testing
tools and suitable tests, errors due to defective pressure sensors or untight Oxi-

You can check the OxiTop

-IDS measuring heads with the following proce-
dures.

5.5.4 OxiTop
®
PM-Test (Cal test)
The test checks the tightness and calibration of the pressure measuring system
with the aid of a chemically simulated BOD.
The
OxiTop
®
-PM calibration tablet contains, among other, a defined amount of
sodium sulfite. The oxygen in the sample bottle oxidizes the sodium sulfite to
sodium sulfate. This process consumes the oxygen present in the sample bot-
tle. The reduction of oxygen causes a defined negative pressure. The BOD
value corresponding to this negative pressure is given in the packet.
The procedure is similar to a BOD5 measurement with
specified sample volume (164 ml) and
addition of the calibration tablet
Details on sample preparation and steps of the test: see operating manual of
the OxiTop
®
-PM test resource.
The test is started in one of the following ways:
OxiTop
®
-IDS measuring head without wirelessly connected meter:
BOD5 measurement (with defined sample volume)
OxiTop
®
-IDS measuring head with wirelessly connected meter:
BOD5 measurement (with defined sample volume, menu-guided test)
Starting with the
meter
Details on the tests are given in the operating manual of your Oxi-

-IDS measuring head.
The test OxiTop
®
-PT (pneumatic test) is operated exclusively at the
OxiTop
®
-IDS measuring head. The meter is not required for this.
1
Open the OxiTop set management.
2
Using <CAL>, start the OxiTop
®
PM test.
The calibration is stored as a BOD5 measurement among the other
active sets.
"CAL" is used automatically as name for the Set.
"A" is used automatically as the name for the sample.
3
Assign an OxiTop
®
-IDS measuring head to the current sample.
The assigning is done similar to creating a sample for measurement
(see section 5.1.2 T
HE COURSE OF THE MEASUREMENT).
