CALCULATION PROCEDURES
6.1
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 [RESULT],
zero measuring by [ZERO].
6.1.1
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 10 - ERROR MESSAGE / CORRECTION).
Example: The reading exceeds the programmed upper limit.
6.1.2
Fundamental to the tempering ...
Tempering switched on or off is parameter of a method.
After switching on the tempering it lasts up to 15 minutes until a constant temperature of 37 °C is reached.
The current temperature of the cuvette 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.
6.1.3
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 aborted by pressing the touchscreen at any place for a long time.
