2.2 Inserting the batteries
Before operating the system for the first time, the batteries included in the package must be
installed.
Dispose of used
batteries in
accordance
with the local
regulations.
Insert the batteries into the compartment, heeding the + and –pole indicators.
Recommendation
Do not use rechargeable batteries!
Saving data - Important notes
Before changing the batteries, please shut down the instrument first. Otherwise the date and
time settings are lost. During battery change, data in the RQflex® 20 reflectometer is saved for
60 seconds. If the change time exceeds 60 seconds only date and time are lost, all stored data
and settings are still stored.
Recommendation
Replacement batteries (AAA non-rechargeable alkaline batteries, 1.5 V) must be on hand for
immediate insertion.

2.5 Initial calibration
The instrument needs to be calibrated before the first measurement 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 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).
3 Measurement
There are two scenarios on how to start a measurement:
1. The desired method is not yet saved in the instrument.
Continue with chapter 3.1.
2. The method is already saved in the instrument.
Continue with chapter 3.2.
3.1 Add a new method
There are two scenarios for adding a method:
1. Guided way
2. Shortcut
