5.3 Assembling the analytic balance

Page 12
5.5 Power supply
Before connecting the device to the mains, make sure that the mains voltage is
230V AC and 50Hz and an earth connection is provided.
Operating the balance at a lower or higher voltage may destroy the device.
5.4 Levelling the analytic balance
In order to obtain accurate and repeatable measuring results, it is important to
align the balance accurately using the level indicator and the two setting wheels.
Turn the foot screws until the air bubble of the water balance is in the prescribed
circle.

Page 13
6 Preparation
6.1 Preparation of sample
Always prepare only one sample for the measurement. This prevents the sample
from exchanging moisture with the ambient air. In case several samples have to
be taken at the same time, put them into airtight containers.
Before the sample is spread on the aluminium pan, the empty aluminium pan
should be placed on the balance and the balance should be tared (display of
0.000 g).
Now spread the sample on the sample pan evenly and in a thin layer to get re-
producible results. Recommended layer thickness: 2 to 5 mm.
An uneven application of the sample causes inhomogeneous heat distribution
in the sample to be dried. This means that the sample is dried incompletely or
that the drying time is increased. Due to piling material, the upper layers will
heat up more strongly, which will cause combustion or incrustation. An exces-
sively high thickness of the layer or possible incrustations prevents the moisture
from leaving the sample. The residual moisture makes the measurement results
non-verifiable and non-reproducible.
6.2 Tools and accessories for sample preparation
The tools and instruments used for sample preparation have a huge effect on
the accuracy and reliability of the measurement. You should avoid tools with
heat-conducting properties, i. e. which are able to transfer heat to the sample.
Improper handling and preparation of the sample will falsify the end result of
the measurement.
Re-using a sample pan can falsify the end result of the measurement because
of the adhering residues. Therefore, always take care to use only well-cleaned
aluminium pans.

Page 14
6.3 Preparation of analytic balance
Switch on the balance at least 30 minutes before starting a measurement. This
ensures that the balance is at operating temperature.
Before each measurement, check that the sample pan is empty and remove any
kind of pollution if present.
7 Operation / Measuring procedure
7.1 Switching the device on
Press the „ON/OFF“ button for switching the device on. After switching on, the
last used settings are called up. These settings are shown on the display.
7.2 Drying modes
Press the „Menu“ key to get to the drying mode selection screen. Here you can
select different drying modes and set up new ones.
On the left-hand side of the display flashes a number which indicates the
memory location. Here you can retrieve up to 16 different memory locations,
using the arrow keys „UP“ and „DOWN“. The saved drying parameters are
displayed along with the selected memory location.
If you wish to use the drying parameters of a certain memory location, press the
„TARE“ key. The analytic balance will then take over the drying parameters and
you can start the measurement.
If you want to save some new drying parameters to a memory location, select
the memory location and confirm by pressing the „ENTER“ key.

Page 15
7.2.1 Specifying the heat-up mode
After the selection of the memory location, the drop icon will flash in the upper
side of the display.
Here you can select one out of three heat-up speeds.
Standard heat-up mode
This is the default mode which is suitable for most sample types.
In this heat-up mode, 120 °C are reached after approx. 4 minutes.
Quick heat-up mode
This mode is suitable for samples with a high moisture content.
In this heat-up mode, 120 °C are reached after approx. 1 minute.
ATTENTION: When using this heat-up mode, there might be in-
creased temperatures in the drying chamber for a short period as
the sensor and the control need some time to regulate the tempe-
rature.
Slow heat-up mode
This mode is suitable for samples with a low moisture content.
In this heat-up mode, 120 °C are reached after approx. 8 minutes.
ATTENTION: When using this heat-up mode, it is particularly
important that the drying time of the sample is adapted to the
drying mode as otherwise the drying process could be terminated
(time expired) although there is still some residual moisture in the
sample.
Select the desired heat-up mode using the arrow keys „UP“ and „DOWN“. To
confirm the selected heat-up mode, press the „ENTER“ key.

Page 16
7.2.2 Specifying measurement / stop mode
After the selection of the heat-up mode, the bar icon will flash in the upper side
of the display. Here you can select between three measurement /stop modes.
Constant measuring value
In this measurement / stop mode, the measurement is stopped
automatically when the measuring value is constant over a certain
period of time.
Manual / user stop mode
In this measurement / stop mode, the measurement can be ended
by the user. To do so, press the „START / STOP“ key.
ATTENTION: Depending on the temperature, combustion of the
sample can easily occur in this measurement / stop mode. This
mode should only be used if constant monitoring can be guaran-
teed. The advantage of this mode is that the sample can be dried
for a long time to allow moisture to escape which is located very
deep in the sample.
Time stop mode
In this measurement / stop mode, the measurement is stopped
automatically when the set measuring / drying time has passed.
ATTENTION: The maximum measuring / drying time you can set is
99 minutes.
The desired measurement / stop mode can be selected by means of the arrow
keys „UP“ and „DOWN“. To confirm the selected measurement / stop mode,
press the „ENTER“ key.

Page 17
7.2.3 Setting the drying temperature
After selecting the measurement / stop mode, the temperature indication will
flash in the upper side of the display.
Here you can set the drying temperature using the arrow keys „UP“ and „DOWN“.
The first setting can be made in steps of 10 %. After confirming with the
„ENTER“ key, the setting can be carried on in increments of 1 °C.
ATTENTION: During temperature regulation, temperature fluctuations of
approx. 4 °C can occur. Mind this when selecting the temperature to make sure
the sample does not scorch. Otherwise, the moisture reading will be falsified.
7.2.4 Setting the drying / measuring time (only in the time stop mode)
Depending on the previously set measurement / stop mode, the time indication
flashes in the upper side of the display.
The drying / measuring time can be set using the arrow keys „UP“ and „DOWN“.
To confirm the set drying / measuring time, press the „ENTER“ key.
ATTENTION: The maximum measuring / drying time you can set is 99 minutes.

Page 18
7.3 Measurement
Prepare the sample and place it in the drying chamber. Select the correct drying
program for your sample as described. Start the measurement by pressing the
„START“ key.
After the measurement, the measured values will be available until they are
deleted. Pressing the „CONVERSION“ key, you can switch between the weight
indication /dry matter indication in % and the indication of the moisture con-
tent in % during and after the measurement. After the measurement, the mea-
suring values last determined must be deleted from the memory. To do so, press
the „RESET“ key.
ATTENTION: Before placing the next sample on the sample pan, make sure that
the display shows 0.0 g respectively 0.00 g. If this is not the case, press the
„TARE“ key.
Hot surface!
• Do not touch the halogen lamps or the cover during or after
the measurement as this can cause severe burns.
• After the measurement, let the sample cool down before
touching it.
7.4 Adjustment / calibration
The moisture analyser consists of a weighing unit and a drying chamber. The
moisture measurement is carried out on the basis of the weight loss of the sam-
ple.
ATTENTION: The moisture analyser internally has a higher weighing resolution
than the one indicated. The moisture analyser uses the higher resolution which
is invisible to the user for calculation. This can result in deviations after the deci-
mal point when trying to reproduce the result.
The weighing unit can be adjusted by means of a 100 g external test weight
(min. M1). Special care must be taken when positioning the scales (as little
vibration as possible and balanced by means of the level). The adjustment of
the weighing unit should only be carried out after a heat-up time of at least
30 minutes.

Page 19
To do so, press and hold the „RESET“ key for approx. 6 seconds. The display
shows „-CAL-“.
After the “-CAL-” indication, “100.00 g” will flash.
Now place the 100 g calibration weight in the middle of the weighing platform.
The indication will change from “100.00 g” to “=====”.
When the indication changes from “=====” back to “100.00 g”, remove the
weight from the weighing platform. After this, the display will show “=====”
again and change to “0.00 g” automatically.
The adjustment of the balance is now finished.
