Initial Calibration; Measurement; Add A New Method - Sigma-Aldrich Reflectoquant RQflex 20 Guía Rápida

2.5 Initial calibration

The instrument needs to be calibrated before the first measure-
ment is performed. This is required to set the correct baseline
for the reflectometric optics. For this purpose, a Reflectoquant
Recalibration Set is delivered with the instrument. Please use
EN
the barcode and the plastic test strip for calibration (for details
of the Recalibration Set see Operating Manual). Keep the
instrument at room temperature for at least 30 minutes.
Select [Quality Assurance] in
the [MAIN MENU].
Select [Calibration].
Confirm your selection by pressing
[OK] or [Right (Next)].
Follow the instruction shown on the display.
Correct insertion of the test strip:
Insert the calibration strip of the
recalibration set into the strip adapter
with the beveled edge outwards and
upwards.

A calibration has to be repeated
• after changing/cleaning of the strip adapter
and/or the internal standard
• in the case of suspect measurement results during the
®
boot up (self-check test failed)
• in the case of error messages E07 or E10
(after cleaning the optics)
• in the case of RQcheck failure (error messages E09
and E11)
• in the case of suspect measurement results
• after severe mechanical distress (e. g. after dropping the
instrument).
