Selecting the Measurement Mode

DMA 35 provides three different measurement modes - "Precise", "Fast" and
"Manual". According to the measurement mode selected, different stability criteria
have to be fulfilled before the result is stored. The stability criterion is always related
to the temperature:
• When the measurement mode "Precise" is selected, the result is stored as soon
as the measured temperature value stays within 0.2 K for 10 seconds. This
measurement mode delivers the most accurate results, but may take a longer
time in case the sample temperature differs greatly from the ambient
temperature.
• When the measurement mode "Fast" is selected, the result is stored as soon as
the measured temperature value stays within 0.4 K for 10 seconds. This
measurement mode delivers quicker results than the "Precise" mode, but as the
density is highly temperature dependent, the measured result is not that
accurate.
• The measurement mode "Manual" enables you to decide yourself when to store
your measurement result. The result is stored immediately after pressing the
<Store> key on the backside of the instrument.
1. Press <Menu> and select "Measurement Mode".
2. Select the preferred setting (Precise, Fast, Manual) and press <Save>.

Using the RFID Function (Only for Versions with RFID Interface)

The product versions DMA 35 Tag&Log, DMA 35 Ex and DMA 35 Ex Petrol are
equipped with an RFID interface, enabling you to uniquely link an RFID tag to a
method and/or sample ID. The RFID tag can either be allocated to a sample ID and/
or method on the instrument or can be programmed accordingly. By reading the RFID
tag that has been uniquely allocated to a method and/or sample ID or programmed
accordingly, when the instrument displays the main screen, this method and/or
sample ID is automatically used for the following measurements.

9.5.1 Preconditions for Using RFID

The reading range of the RFID receiver integrated in DMA 35 is about 2 cm. The RFID
tag has to be situated within this area to enable data exchange with DMA 35.
TIP The larger the diameter of a tag, the larger is the reading range.
