• "reset sample identif.": Select if the entered sample identification should be
deleted after the measurement.
• "API input": Select the kind of density for calculating the API functions:
density, density (not viscosity correct.), special adjustment 0-4.
DMA 5000:
• "delay": This function is only available when a temperature scan is activated.
When measurements are carried out with the temperature scan, a "delay
time" (from 0 to 9999 minutes) can be entered: After reaching the new
measuring temperature, the DMA 5000 waits for the set time before the
measurement is carried out.
• "temp. scan": Measurements by different temperatures are performed
automatically. Start, end and step values can be entered.

Calibration
7.1

Definitions

Adjustment of the density meter:
• The process of bringing the instrument into a state suitable for use, by setting
or adjusting the density instrument constants.
Calibration of the density meter:
• Various processes for establishing the relationship between the reference
density of measurement standards and the corresponding density reading of
the instrument.
• Calibrations are performed to determine the deviation of the displayed
density values from the reference values of density standards.
7.2

Checking Procedure: Density Check

The "density check" function allows you either to check the validity of the factory
adjustment after transport or the validity of your own adjustments.
• To check the factory adjustment, pure water is used as calibration fluid.
• To check your own adjustments either degassed, bi-distilled water or
different density calibration fluids or standardized samples can be used.
