Safety instructions
Always transport the device in an upright position
and protect it from impact.
Always operate the device on a
level surface, using a vibration-free base.
Avoid draughts.
Never touch the (luminous) heater when it is hot,
as there is a risk of injury!
Always disconnect the plug from the mains supply before
performing any work on the device (e.g. changing the heater)!
Repairs should only be carried out by a qualified technician.
Please take extra care when using flammable samples!
You may need to contact the manufacturer for advice.
Please be careful not to drop any sample particles
next to the tray support plate.
Carefully remove any particles with
a vacuum cleaner.
Only use accessories specifically designed for use with ULTRA X devices.
Do not move the device during measurement, as this will result in measuring errors.
Do not leave any substances in the measuring tray, if they are not being measured.
Devices should only be shipped in the original packaging using the original packaging material.
ULTRA X moisture analyzers are stand-alone units and are not designed to be used in continuous
production runs. Any such use is at your own risk.

Warranty
a&p instruments undertakes to repair faulty devices within the warranty period, free-of-charge, if the defect is
a manufacturing fault. This warranty covers the repair of spare parts and working hours required. It does not
cover normal wear-and-tear and soiling and staining of the device. a&p instruments will not accept any
freight costs.
This warranty does not apply to:
improper use of the device,
use of the device for purposes other than those stated by a&p instruments,
mechanical damage or damage caused by fluids or sample matter,
incorrect set up or wrong electrical wiring,
mechanical damage of the load cell e.g. as a result of being overloaded
Transport, packaging, installation site
Please check the packaging and device for any damage upon delivery.
Please retain the original packaging in case you need to return the goods to a&p instruments.
Please only use the original packaging when returning the goods.
Accessories supplied:
Tray holder 2 trays Tray tongs Mains cable
Start-up
1. 1. Place the device on a stable, vibration-free surface, as level as possible and
protected from draughts. The most suitable locations are the corners of a room,
rooms with only one entrance and heavy tables on concrete floors.
Remove the protective film from the front foil.
1. 2. Swing the heater back until the resistance.
1. 3. Place the tray holder on the device:
First place the tray holder carefully on the two pins, the distance
between the housing and the tray holder should be approx. 1.5
– 2 mm. Do not exert to much power on the balance!
Then put on the shielding plate unit.
To remove the tray holder, first carefully lift up the
shielding plates and then carefully pull out the tray
holder in the middle with very slight tilting
movements, do not exert too much power!

1. 4. Next place one of the two drying trays supplied on
the tray holder using one or two sets of tongs.
The notch in the reflector tray acts as an access
gap for easy positioning of the tray.
1. 5. Check that the voltage indicated on the type plate matches the local mains voltage.
1. 6. The power cable is inserted into the
device’s power jack and a suitable
earthed mains supply. After the power
supply has been connected, the
device can be switched on or off using
the on/ off button on the back of the device.
Once the device is switched on, the current
software version is shown, followed by the
weight display.
1. 7. In order to prevent weighing system measuring errors, the device should be switched on 20 minutes
before being used to allow for heat compensation. If weight values vary in the display’s milligram range
during this period, this is considered normal within this phase. If the device is switched off using the reset
(on/ off) button, it does not require a warm-up period, if switched on again with the same button.
1 8. ULTRA X moisture measuring devices are supplied, so that in most cases substances can be measured
immediately. If you are not satisfied with the result, the measurement parameters can be adjusted:
Printer
Open Cover: Change Paper Line feed
Hold the green glowing putton
and lift the plastic cover
The ULTRA X Thermo paper is stable for 10 years.

Temperature control
Value is stored
Value is stored
The temperature that is set on the device relates to
the thermal radiation that hits the sample to be dried.
The thermal radiation is an electromagnetic wave for
the transmission of energy. As this energy creates heat in the sample, the moisture evaporates from the
sample. The temperature is used to set the energy that allows the moisture to evaporates from the material
(more temperature is more energy).
The set temperature is not to be equated with the temperature to which the material or the environment heats
up.- The material or ambient temperature is a consequence of the drying process, not the cause of the drying.
Automatic shut-off or timer
The automatic mode dries the sample until a constant weight is reached and then switches off the heater.
The following settings
can be defined here:
1. Weight loss in mg
a value should be defined here which corresponds to approx. 0.1 % of the original sample e.g. original
sample 10 g = 10 mg
When the weight loss <= the mg weight specified here within the interval period defined below, the
measurement is completed, if at least the start of query time limit has expired.
2. Query interval in secs.
an interval should be selected here, so that the sample is not dried for too short a period but also not for
far too long. A period of 20 to 30 secs is normally adequate. None /10-99 secs can be selected.

3. Start of query in minutes
Specify the drying period required for the samples without automatic mode. The factory-set 3 minutes
are usually adequate. This value should be increased for extremely low temperatures, so that the device
does not switch itself off prematurely. This affects the UX 3031 in particular, when free moisture is being
measured at 45°C. You can select 1-99 mins.
The timer setting is the same as described for the quartz heater.
It is possible to select a drying time of 1 – 180 mins
The automatic settings are the same as described for radiant heaters.

Moisture analysis process
The device should be connected to the mains supply and switched on with a drying tray. A weight value is
displayed.
Set scales to zero using the ‘tare’ button,
display ‘0.000 g’.
Evenly distribute approx. 50 - 200 g
sample matter in the tray and wait
for the readout to stop.
1.
2. Swing the heater over the sample, switch on the
heater switch and the drying phase begins.
Header data is now printed for devices with a built-in
printer. The sample is dried until it has reached a
constant weight; the heater then switches off
automatically. The time and measurement value is
printed for devices with a printer.
If you do not wish to make any measurements,
please always ensure that the heater is swung back
to its rearmost position!
3. Measurement values are displayed for the entire length of timethe heater is positioned above the sample.
The device should not be moved from its position during measurement, as this causes measurement errors.
The external printer prints the following
at the start of the measurement:
Model, device ID,
date, time,
heater temperature,
timer or shut-off parameters, initial weight.
And after the device has finished measuring, once the
heater has been swung back to its rearmost position:
Measurement value,
measurement time,
substance,
initials
Please ensure drying trays have cooled down before using for measurement.
If the measurement ends before
it is complete,
the display shows: to sample weight.
For substances which are difficult to remove from the
tray after being dried, we recommend using foil trays,
which can be made quickly and economically from
aluminum foil using the ULTRA X foil press.

Data interface
Weighing data, temperature and drying data are also shown on the display via a standard USB flash drive and
serial interface.
Depending on the model, a separate UX 3092 printer or a computer can be connected to the device.

Parity check none
Handshake none
Data transmission using a USB flash drive
If the computer receiving the data has an internet connection, the system automatically installs a driver
and creates a COM interface, as soon as the computer is connected to the moisture analyser.
If this is not the case, the driver must be manually installed in the device manager.
Special software is required for transmitting data to a PC:
ULTRA X DataBridge
Data can be exported in four different data formats: . xls; .PDF.
The software is extremely easy to install and use:
Connect devices, place CD in PC, the installation is self-explanatory.
