ULTRAMAT 23
152 Manual, 3/2016, A5E37100388-003
Configuration: Device test: Display/keys/flow
You can select the following three tests in this menu.
In this test, all characters in the character set of this a
are output in succession at every position of the display. The
display remains empty if characters are output which cannot
be displayed. This is a cyclic test, i.e. once the complete
character set has been processed, it starts from the
beginning again. The test is repeated continuously until
terminated by pressing the <
> key.
A corresponding message will inform you of this before the
test is started.
This test takes 30 s, and the time remaining up to the end of
the test is output on the display. During this time you can
press all input keys in succession. The analyzer normally
recognizes that a key has been pressed and indicates this.
This test cannot be prematurely cancelled.
This indicates whether the sample gas flow is correct or not.
Depending on the type of gas supply, it may be necessary to
switch on the pump using the
key.
Configuration: Device test: Inputs/outputs
In this menu you can call the tests of the electric inputs and
outputs of the analyzer. You require the following equipment to
carry out these tests:
Ammeter
Ohmmeter
Power supply (24 V DC)
Test plugs
Configuration: Device test: Inputs/outputs: Test analog outputs
lyzer has four analog outputs and an output current
... 20 mA. You can test these by setting any val-
ue of the output current between 0 and 20
mA in this menu dis-
To test these outputs, connect an ammeter to the correspon
d-
ing analog outputs on plug X80 and measure the output cu
r
rent.
The pin assignments of plug X80 are described in section
