CALCULATION PROCEDURES
5.1
GENERAL NOTES
The device offers operator guidance in the display by a combination of plaintext and short terms.
Messages and inputs regarding the method always have to be confirmed by [OK]. By [EXIT] all methods can be
broken off. For a restart see chapter 4 - PROGRAM SELECTION. Measuring is generally triggered by sipping
lever [P] or [RESULT], zero measuring by [ZERO] and sipping lever [P] (chapter 3.5.2 - Working with original
flow-through systemand 3.5.3 - Working with standard cuvettes -).
5.1.1
Fundamental to the handling ...
•
Before measuring with standard cuvettes the lid of the cuvette compartment is to be closed.
•
Deviations from normal operation, caused by the device or by the operator, are notified by
“ERROR”. They always have to be confirmed by [E] (chapter 9 - ERROR MESSAGE /
CORRECTION).
Example 1:
The reading exceeds the programmed upper limit
Example 2:
Too little liquid when sucking in a measuring solution
5.1.2
Fundamental to the tempering ...
•
Tempering switched on or off is parameter of a method.
•
After switching on the tempering it lasts up to 10 minutes until a constant temperature of 25 °C, 30 °C
or 37 °C is reached.
•
The current temperature of the flow-through cuvette or of the cuvette adaptor is shown at the Iower
edge of the touchscreen. For meaning of the display see chapter 4 - PROGRAM SELECTION /MAIN
MENU. A temperature instable or out of tolerance during measuring is marked by an asterisk (*) at the
utmost right position in the corresponding print line.
To avoid deviations due to temperature influence a delay between triggering and actual measuring can
be programmed in each method.
•
For a quick mode of operation all temperature-sensitive samples, reagents and washing solutions
should be externally tempered by Incubator T12/T16 (REF 500-002 / 500-001) or a water bath.
5.1.3
Fundamental to the inputs ...
•
The input format of the factor and/or the standard with sign determines the output format of the result
concerning the number of decimal places.
Example: With factor “36.8” the calculated concentration will be shown with one decimal place.
•
Each factor or standard can be minus signed, so that the result is calculated with correct sign.
Example: The test GOT is programmed with the factor “-1746“ because the measuring principle implies
a decreasing absorbance.
•
For a homogeneous solution the input of a delay before a measuring is possible at all methods.
•
All delay times can be cancelled by pressing the aspiration tube [P] for a long time.
