MAIN MENU’ > F5 SERVICE > F2 WASHINGS > F2 WASHES

F2 WASHES : Used to determinate the number of XX complete washes of the hydraulic

circuit SAMPLING/ASPIRATION ( min 1, max 99 ).
This is useful when we want to wash the hydraulic circuit very accurately but

We don’t want remain in front of the instrument.

MAIN MENU’ > F5 SERVICE > F2 WASHINGS > F5 AUTOZERO ( MONOCUVETTE )

F5 AUTOZERO : Used to execute an autozero of the complete filter wheel.

In case that during the autozero there are no variations respect the previous
Values the cycle will be terminated without any signal.

MAIN MENU’ > F5 SERVICE > F2 WASHINGS > F5 AUTOZERO

F5 AUTOZERO : Example of autozero with a variation in the reading.

A variation of +/- 5% is shoved with the visualization of the following voices:

ESC : ABORT – Cancels the session
F1 : REPEAT - Repeat the session of autozero
ELSE : ACCEPT – Pressing any key except the key “ ESC “
or “ F1” we accept the new value visualized

EVERY TIME THE AUTOZERO GETS BLOCKED, PRESS F1 TO

RESTART THE PROCEDURE

MAIN MENU’ > F5 SERVICE > F2 WASHINGS > F5 AUTOZERO

F5 AUTOZERO : Example of autozero with a problem.

In this particular case we have the lamp which is not functioning.

This can be noted since the values of all filters are very similar if not equal
to the FILTER 0 = OFFSET

MAIN MENU’ > F5 SERVICE > F3 DIAGNOSTICS

F1 READING TEST : Used to execute the reading tests in mV or to execute the regulation

of the offset and the gain

F2 O.D. TEST : Used to execute readings in absorbance

F3 HARDWARE TEST : Used to execute tests of MECHANICAL/ELECTRONICAL functionality

F4 PROCEDURE TEST : Execute a complete test divided in single operation

F5 : Reserved key

MAIN MENU’ > F5 SERVICE > F3 DIAGNOSTICS > F1 READING TEST ( MONOCUVETTE )

F1 READING TEST : Remove the aspiration needle and put it in a holder with distillated

water.
Press F3 ASPIRATE to aspirate.

After you have aspirate water, select the filter 1 = 340 nm.
You get visualized the reading of the filter in mV and in digit.

Using the trimmer of the gain we can increase or decrease the value
of the reading.

Act on the gain trimmer to have a reading  1300 mV.
You should keep in mind, that once you act on the trimmer of the
gain to modify the reading of all the filters on board to the filters
wheel.

To execute the regulation of the offset select the Filter 0 = NULL
and act on the relative trimmer to have a reading > 1 mV.

Once the regulation of the gain and the offset is done, it’s necessary
To execute an autozero to be able to memorize the new values.

THE OPERATIVE RANGE FOR EVERY SINGLE FILTER IS 500 mV ÷ 1800 mV
