Instrument settings and analysis
Please read the following information before carrying out the required
settings at the instrument.
Instrument settings
The required instrument settings for executing analyses, e.g. measur-
ing interval pause, indicator bottle size and behaviour of relays 1 and
2, are carried out on the controller board using the function keys and
slide switches. Please refer to the section
808" on page 18 for a detailed description.
Double assignment of the function keys
The four function keys at Testomat
basically have two functions.
A short or long key press (at least 2 seconds) is required for opera-
tion.
A short key press activates the top functional level (displayed in black
on the key). A long key press is required to activate the bottom key
function (displayed in white). Please refer to the section entitled
"Operating elements/Function
the individual functions.
Displaying operating statuses and measuring results
Only LEDs are used to display operating statuses and measuring
®
results at Testomat
Depending on the status or measuring result, the LEDs can either
flash or illuminate continuously (see the section entitled
elements/LEDs" on page 13).
Limit value display
®
Testomat
808 is a pure limit value measuring instrument
which uses two limit value LEDs to display the measuring
result.
The green LED illuminates when the limit value specified by the
selected indictor is not achieved during the analysis.
The red LED illuminates if the limit value is exceeded.
If a new measurement is running after completion of another
measurement, the result of the previous measurement flashes in the
display. The respective LED displaying the result of the previous
measurement illuminates continuously during the interval pause.
Both LEDs are switched off if an error occurred during the pre-
vious measurement.
