2 DMA 4100/4500/5000 M – An Overview
6XDLIB017EN-E
2 DMA 4100/4500/5000 M – An Overview
The density measurement is based on the
oscillating U-tube method, which has been first
introduced on the market by Anton Paar in 1967.
State-of-the-art digital density and concentration
meters have been developed to combine highest
precision with easy operation and robust design.
Your DMA M series instrument is equipped with the
world's most advanced digital density measurement
technology. This “Pulsed Excitation Method” and
various features supporting your density measure-
ments are described below.
Inside DMA 4100/4500/5000 M
• The oscillation periods of the U-tube and the
reference oscillator are measured by optical
pickups.
• Two integrated Pt 100 platinum thermometers
together with Peltier elements provide an
extremely precise thermostatting of the sample.
• ThermoBalance™: The additional reference
oscillator provides long-term stability and
enables precise measurements over the whole
temperature range of the instrument, with only
one adjustment at 20 °C.
• Viscosity-related errors are automatically
corrected over the full viscosity range by
measuring the damping effect caused by the
viscous property of a sample. The result is
subsequently used for the calculation of the
viscosity corrected density value.
Condition monitoring
• The built-in sensor for the atmospheric pressure
enables the automatic calculation of the current
air density required for adjustments and checks
of the instrument, as the air density is dependent
on the atmospheric pressure.
• FillingCheck™: A major source of measuring
errors with density meters are gas bubbles in the
measuring cell. The instrument automatically
detects inhomogeneities and gas bubbles in the
whole measuring cell by an advanced analysis
of its oscillation pattern. Where necessary, a
warning message is generated in real time for
every single measurement.
• U-View™: Real-time images by a camera with
zoom function enable you to visually inspect the
measuring cell.
• The patented “Pulsed Excitation Method”
(AT 516420 (B1)) even improves operational
safety, as the condition of the measuring cell
can be monitored in detail.
User interface
The touchscreen user interface facilitates easy and
intuitive operation in routine applications as well as
in demanding scientific research work:
• For the most common applications, 10 measur-
ing methods are predefined. Just select the
method fitting your application, or create your
own methods.
• Density values are automatically converted into
concentration values for a large number of
factory-programmed substances. You can add
further substances as required by yourself.
• Optionally operate DMA 4100/4500/5000 M via
an external keyboard, a mouse, gesture control
or a bar code reader.
• Optionally connect an external monitor or
touchscreen (VGA interface).
Compact and robust design
The instruments of the DMA M series are ready for
reliable measurements also in demanding
environments thanks to the following strengths:
• Compact design
• Sealed housing that withstands shocks, dirt,
and spillages
• Robust housing materials: coated aluminum
(top and sides), aluminum (base and back), and
polystyrene/butadiene (front)

equipment
- in direct sunlight
3.2 Mounting the Injection Adapters
1. Take two injection adapters with screws from
the accessory kit.
2. Pull out the black plastic transport plugs from
the tips of the injection adapters.
TIP: Keep the plastic transport plugs for later use.
They can be used as an injection adapter tool to
widen the tips of the adapters in case of leaks.
Fig. 4: Mounting the injection adapters
3. Carefully insert the injection adapters into the
openings of the adapter holding plate on the
right side of the instrument, see fig. 4.
4. Push both adapters towards the holding plate
with moderate force.
5. Insert the screws through the bore holes of the

adapter holding plate until some resistance
against further turning can be felt.
WARNING
Using hazardous or flammable chemicals as
samples or cleaning liquids could lead to
damage of the instrument and cause serious
injuries unless special precautions are taken.
• Observe the safety instructions in the section
“Special precautions for flammable chemicals”
in section 1.
NOTICE
• Ensure that the power plug and the power
switch are always easily accessible so that the
instrument can be easily disconnected from
the AC power supply at any time.
• A strong built-in cooling fan dissipates heat
through the bottom and the rear of
DMA 4100/4500/5000 M. Ensure that the air
flow is not blocked, and provide for a minimum
distance of 10 cm (4 in) to walls behind and
beside the instrument.
• High humidity or a measuring temperature that
is significantly below the ambient temperature
may lead to condensation in the measuring
cell. Install a drying cartridge to avoid
condensation, see the Reference Guide.
CAUTION
If the screw for fastening the adapter is
overtightened, the density measuring cell may
be damaged. Harmful liquids leaking from the
instrument may cause injuries.
• Tighten the screw until some resistance
against further turning can be felt, and then
stop to tighten the screw.
The gap left between the holding plate and the
adapter, where the thread of the screw can be
seen, is approx. 3–8 mm (approx. 0.12–0.31 in).

3.3 Checking for Leak Tightness
1. For DMA 5000 M: Insert the adapters Luer ¼"
UNF into the openings of the injection adapters.
2. Close one adapter tightly with a male Luer plug.
3. Use a plastic syringe from the accessory kit to
inject, with moderate pressure, air through the
other adapter.
4. Wait a few seconds.
5. Release the plunger of the syringe.
- If the connections are tight, the plunger of
the syringe will be slowly pushed back by the
pressure in the measuring cell.
- If the connections are leaky, the plunger of
the syringe will not move.
In this case, repeat the mounting of the
adapters.
TIP: Keep the plastic transport plugs for later use.
They can be used as an injection adapter tool to
widen the tips of the adapters in case of leaks.

Fig. 6: Mounted PTFE hoses
3.5 Connecting the Cooling
Only for DMA CK versions.
When you perform measurements at temperatures
lower than 20 °C (36 °F) below ambient tempera-
ture, connect the cooling to an external thermostat.
If your tap water is cool enough, also connecting to
a tap water supply will help. Operate the cooling with
a moderate flow of water (1–3 liters per minute).
Example:
Your ambient temperature is 25 °C (77 °F), and you
want to perform measurements at 0 °C (32 °F).
Connect the DMA M CK to an external thermostat or
tap water line that is delivering water at a constant
temperature between 5 °C and 15 °C (41–59 °F),
and change the measuring temperature to 0 °C
(32 °F) in the “Density Module” dialog.
3.6 Switching the Instrument On/Off
1. Connect the power inlet of the instrument with
the AC power supply by the power cord.
2. Switch the instrument on using the power
switch on the rear of the instrument.
The glowing green LED on the front side of the
instrument indicates that the power is on.
3. Wait at least 15 minutes for the temperature to
stabilize.
After power-on, the instrument needs approx.
15 minutes for temperature equilibration and
internal temperature adjustments. During this
time “temp. equilibration” is displayed.
TIP: Do not turn off the instrument during the night.
This allows the measuring cell to achieve long term
temperature stability.
4. To switch the instrument off, use the power
switch.
IMPORTANT: If you have to restart the instrument,
switch it off and wait until the green LED on thefront
has gone out before switching the instrument on
again.

select Checks/Adjustments > Checks. Proceed
as described in section 4.2.2.
4. If the check results are both OK, the instrument
is ready for routine measurements.
5. If any check result is not OK, clean the
measuring cell thoroughly and repeat the
check.
6. If the check result is still not OK, perform an
air/water adjustment, see section 4.3.1.
4 Checking, Adjusting, and Calibrating
4.1 Definitions
Checking
Checking the correct operation of an instrument by
measuring a sample of exactly known measurement
properties, and comparing the result with the
expected values.
Adjusting
Ensuring correct measurements in the future by
filling in a sample of exactly known measurement
properties (standard), and adjusting the instrument
constants in a way that the known correct results are
found by the instrument.
Usually, for a successful adjustment, at least two
standards are needed with measurement properties
that encompass the expected measurement results
of your samples.
Calibrating
Calibrations are checking procedures which are car-
ried out using certified standards. By comparing the
measured result with the standard reference value,
you can validate the quality of your measurements.
4.2 Checks

4.2.2 Performing Checks
By checks, carried out in regular intervals, you can
ensure that your density and concentration mea-
surements consistently deliver results of high and
stable accuracy.
With a density check, you fill a medium of known
density (air, water, or any customer-specific stan-
dard liquid) into the measuring cell and compare the
measured density with the reference value.
DMA 4100/4500/5000 M performs the water checks
and air checks automatically at the measuring
temperature of the currently active method. The
precision class is used according to the selected
method. The density of water and air at the set
temperature is calculated and compared with the
actually measured density. With water checks and
custom checks, the value is calculated for the set
temperature. With air checks, the value is calculated
for the set temperature and the measured air
pressure.
Custom checks ar e defined for a certain method and
are always performed at the temperature of the
selected method with the corresponding precision
class.
Air checks and water checks are available for any
method.
If the instrument is operated in the non storage
mode, no check data will be stored, see also the
General Software Functions Manual, section 9.1.2.
When to do water checks and custom
checks
Use the water check and the custom check to verify
that the instrument is measuring with satisfactory
accuracy. We recommend performing a water
check or custom check every day before you start
your measurements.
Perform additional water checks or custom checks
as required and at your own discretion, e.g. when
you get unexpected results.
NOTICE
When operating the instrument in the non storage
mode, print or export the check results immedi-
ately after the check. Otherwise the check data

14 XDLIB017EN-E
When to do air checks
Use the air check to verify the efficiency of your
cleaning and drying procedure. We recommend
performing an air check every day after the
measurements have been finished and the
measuring cell has been cleaned and dried.
Perform additional air checks as required and at
your own discretion, e.g. after the measurement of
critical samples that might stick to the measuring
cell (e.g. samples containing adhesives, sticky
particles, proteins).
To perform a density check
1. Tap <Menu> and select Checks/Adjustments >
Checks to open the checks list.
2. Highlight a water check, an air check, or a
custom check in the list.
3. Tap <Start> and follow the instructions on the
screen.
For a water check, use freshly degassed ultra-
pure (bi-distilled or deionized) water.
For an air check, clean and dry the measuring
cell thoroughly.
Use the camera image to check whether the
measuring cell is clean or whether water has
been filled bubble-free.
When the check is finished, the following
information is displayed:
- Check name/type and check result
(“Passed” or “Not passed”)
- Date and time
- Method used
- Check result
- User name
- For water checks:
- Reference value calculated for the set
temperature
- Lower deviation
- Upper deviation
- Measured value
- Check result
- Set temperature for the density cell
- For air checks:
- Reference value calculated for the set
temperature
- Lower deviation
- Upper deviation
- Measured value
- Check result
- Air pressure
- Set temperature for the density cell
- For custom checks:
- Lower limit
- Upper limit
- Measured value
- Check result
- Set temperature for the density cell
4. Tap <Print or Export> if you want to print or
export the results of the check.
5. Tap <OK> or <Home> to exit the check routine.
If the water check has failed, we recommend taking
corrective actions until the check is valid again:
• Examine the camera image included in the
results to check whether the water has been
filled bubble-free.
• Check the quality of the water.
• Clean the measuring cell thoroughly.
• If the above mentioned actions do not help,
perform an air/water adjustment.
4.3 Adjustments
If the instrument is operated in the non storage
mode, the adjustment data are not viewable, see
also the General Software Functions Manual,
section 9.1.2.
For detailed information on all other available
adjustments, adjustment data management,
resetting to factory adjustment, and calibrations,
see the Reference Guide.
4.3.1 Performing an Air/Water Adjustment
An air/water adjustment has to be performed if the
water check has failed with “not passed” as result,
and using freshly degassed ultra-pure (bi-distilled or
deionized) water and cleaning the measuring cell
did not help.
The adjustment media are dry air and freshly
degassed ultra-pure (bi-distilled or deionized) water.
The ThermoBalance™ technology allows for
precise measurements over the whole temperature
range with only one adjustment at 20 °C. To achieve
the highest possible precision of measurements at
different temperatures, you can additionally perform
a temperature range adjustment, see the Reference
Guide.
NOTICE
When operating the instrument in the non
storage mode, print or export the adjustment
results immediately after the adjustment.

4 Checking, Adjusting, and Calibrating
XDLIB017EN-E 15
The air/water adjustment takes 5–10 minutes if the
instrument is already clean and dry and equilibrated
to 20 °C.
The adjustment procedure can be aborted by
tapping <Cancel>.
To set the reference values for the
air/water adjustment
The reference values for air can be selected accord-
ing to your needs. They are either based on the
formula of
- Spieweck and Bettin1 or
-CIPM
2.
The reference values for water can be selected
according to your needs. They are either based on
the formula of
- Spieweck and Bettin3 or
-CIPM
4 / IAPWS5.
(The CIPM formula is limited to 0–40 °C only,
so for temperatures above 40 °C, the IAPWS
formula is used.)
The factory adjustment has been set using refer-
ence values for the density of air (humidity 50 %)
and water based on the formula of Spieweck and
Bettin1,3. This formula covers the whole measuring
range (0–100 °C) of the instrument.
1. Tap <Menu> and select Setup > Measuring
System Settings > Density Module.
2. Use the drop-down box “Air Table” to select the
preferred reference table.
3. Use the drop-down box “Water Table” to select
the preferred reference table.
4. Tap <OK> to save your settings.
TIP: Foruseinmetrology,theCIPM densityformula
is the preferred standard over its recommended
range (0–40 °C) at pressures near atmospheric.
The formula should not be extrapolatedoutside this
range.
Densities from the IAPWS formula are consistent
with the CIPM standard within the range of validity
of the CIPM formula. Outside the CIPM range of
validity, the IAPWS formula is the preferred method
for obtaining accurate densities of water.
To perform an air/water adjustment
1. Tap <Menu> and select Checks/Adjustments >
Air/Water at 20 °C.
2. Rinse the measuring cell.
TIP: If you use undenatured ethanol as the final
rinsing liquid, only 3–4 minutes drying time are
required.
3. Tap the <Air Pump on> button to dry the
measuring cell.
4. Tap <OK>.
5. Enter the air humidity and the atmospheric
pressure.
The air humidity is set to 50 % per default.
The atmospheric pressure displayed is
measured automatically by a built-in sensor.
6. Tap <OK>.
The air adjustment routine is carried out.
7. Fill freshly degassed ultra-pure (bi-distilled or
deionized) water into the measuring cell and
tap <OK>.
Be careful to fill the water without air bubbles.
TIP: If the water has been filled without air bubbles,
you can ignore a possible warning message
“Density Condition: filling warning” during the
adjustment routine. A proper adjustment is required
for the FillingCheck™ function.
The water adjustment routine is carried out.
When the adjustment is finished, the following
information is displayed:
- Reference density of water
- Deviation to reference value using old
adjustment constants

NOTICE
You have to readjust the instrument after
changing the selected air and/or water table.
NOTICE
The choice of reference table also affects
derived quantities (e.g. Apparent Density, SG,
API values, etc.).
All factory-set concentration tables consist of
calculated data based on the reference values
according to Spieweck and Bettin.

WARNING
In the unlikely case of malfunction or damage of
the Peltier elements, the heating control of the
measuring cell is affected, and the measuring
cell’s temperature might rise up to 120 °C
(248 °F) (for DMA M with DSP-SAC electronics
up to 150 °C/302 °F).
Liquids can then spurt out of the measuring cell
and potentially cause injuries or fire.
To avoid injuries and fire:
• Ensure that the waste vessel is properly
installed.
• Use method settings that constantly display
the measuring cell’s temperature.
• Check the cell temperature before filling a
sample or starting a measurement.
• Use only the smallest possible sample amount
if you measure aggressive, toxic, or flammable
samples.
• If your sample is toxic or highly flammable,
always handle it in an appropriate environment,
e.g. under a fume hood, and ensure that the
location is sufficiently ventilated.
• Measure only samples with an ignition point
over 120 °C (248 °F) (for DMA M with DSP-
SAC electronics up to 150 °C/302 °F).
• Wear protective clothing and safety goggles.
WARNING
Filling samples and cleaning liquids which the
wetted parts are not resistant to will corrode the
wetted parts. Sample leaking from corroded
parts may cause serious injuries.
Before filling any sample or cleaning liquid into
your DMA M:
• Make sure that all safety instructions
concerning the use of chemicals and the use of
flammable chemicals are met, see section 1.
• Make sure that all wetted parts are resistant to
the filled-in liquid (see appendix A.3). The
chemical resistance depends on the
temperature and concentration of the sample.
• Make sure that you have suitable cleaning
fluids at hand for cleaning the measuring cell,
see section 7.1.
• If an Xsample filling module is connected,
check the resistance of the wetted parts. For
information about the materials, see the
manual of the Xsample.

6Measuring
18 XDLIB017EN-E
Important for high accuracy measurements
If you use a syringe to fill the instrument, use the
syringe holder to fully utilize the instrument’s accu-
racy (especially with DMA 5000 M). Inject the entire
sample volume. The syringe can stay connected to
the filling adapter during the measurement.
Be sure to apply exactly the same filling procedure
for checks, adjustments, and measurements.
Sample amount
If the measuring cell is clean and dry, you need
approx. 1 mL of sample.
If you measure without cleaning and drying between
the samples, you need a higher amount of sample
because you have to flush residues of the previous
sample out of the measuring cell to avoid cross-
contamination.
Bubble detection using the camera –
U-View™
1. Tap in the quick access area to open the
live camera view of the measuring cell.
2. Tap <Zoom In> to get a magnified view.
3. Attach a USB flash drive and tap <Save
Picture> to save the current picture.
4. Tap <X> to exit the measuring cell view.
Fig. 7: Camera window
To fill with a syringe (Luer tip)
Fig. 8: Filling with a syringe
1. Connect the syringe to the sample inlet adapter
or to the adapter Luer UNF ¼" in the top
connector of the syringe holder, see fig. 8.
2. Push the plunger of the syringe slowly and
continuously until a drop emerges from the
sample outlet adapter.
3. Leave the syringe in the filling position during
the measurement.
To fill with a funnel
1. Mount an adapter Luer cone to the sample inlet
adapter.
2. Connect the adapter with a funnel using a
silicone hose (3x5 mm).
3. Fix the funnel in a position higher than the
sample inlet of the DMA M.
4. On the outlet of the DMA M, mount another
adapter Luer cone and connect it to a waste
vessel using a second silicone hose (3x5 mm).
NOTICE
Samples with a moderate tendency to corrode
borosilicate glass, such as strong alkali solutions
(e.g. caustic soda), can be measured with the
DMA M.
• However, take care to remove such samples
immediately after measurement, and rinse the
measuring cells thoroughly.
• Check the validity of the adjustment more
frequently than generally recommended.
• Perform a new adjustment if necessary.
• The measuring temperature for strong alkali
solutions should not be higher than 20 °C.
Higher temperatures dramatically increase the
speed of corrosion.
NOTICE
Do not use syringes that contain lubricants. The
lubricants can dissolve into your sample and
lead to a systematic measuring error.
