Inspections of measurement
technique
2 years acc. law refer to national laws / rules
To execute the tests correctly, please observe the
instructions given in the corresponding sections of
the user manual of the UNIDOSwebline.
Safety inspections must only be handled by per-
sons who are trained in the use of such equipment
and are capable of applying it properly. The opera-
tor must be trained in the use of the device.
The UNIDOSwebline must be inspected at regular
intervals according to national regulations at PTW-
Freiburg or a qualified calibration laboratory.
Safety inspections and inspections of measurement
technique must also be performed after repairs or
after each influence which may have changed the
behavior of the device.
National valid laws or rules may regulate shorter
intervals.

3.2 Constancy Test
The following tests should be executed regularly.
They make it possible to recognize slow alterations
of the characteristics of device or detector.
Test
Interval Accessories
Comment
Detector test
weekly - HV check at detector; only range Low
Device test
weekly - checks device only; only range Low
Long term stability
weekly UNITEST check HV and all 3 measuring ranges; no complete function test
Long term stability
monthly check device no complete function test
To execute the tests correctly, please observe the
instructions given in the corresponding sections of
the user manual of the UNIDOSwebline.
The test results have to be recorded from the first
start of operation in order to be able to make state-
ments about a change. Addionally for detector
tests: the record has to be separate for each detec-
tor.
The checkup of the device can be performed most
extensive with an UNITEST (refer to the user man-
ual of the UNITEST).
A complete function test can take place however
only through a inspection of measurement tech-
nique.
3.3 Maintenance

3.4 Further Tests
Ethernet-interface
The Ethernet interface can be checked using the
VNC Viewer.
TRIP Output
The function of the TRIP OUTPUT can be checked
as follows: set up the threshold and apply a signal
which exceeds the threshold (e.g. using an
UNITEST).
To execute the tests correctly, please observe the
instructions given in the corresponding sections of
the user manual of the UNIDOSwebline.
3.5 System Information
Information about the version of firmware and
hardware and the status of supply voltages of the
device can be read out via service e-mail (refer to
corresponding sections of user manual UNI-
DOSwebline).
The device monitors the supply voltages continu-
ously (Note: These information can be read out only
via service e-mail.)

4 Troubleshooting
The instruction manual of UNIDOSwebline describes
the procedures to apply, if problems occur during
the operation of the device or error messages are
shown on the display. The particular sections are:
10.1 Error Messages on the Display
10.2 Checking the Measured Value
10.3 Problems Operating the UNIDOSwebline
5 Functional units
Opening of the device and working at the device
must be performed only by PTW-Freiburg or by
persons authorized by PTW-Freiburg.
WARNUNG
Shock Hazard – Dangerous voltages become
touchable with the opening of the device. For
the connecting systems BNT and TNC: the en-
tire enclosure of the measuring module is on
the potential of the high voltage. In order to
switch off the device safely, it must be turned off
and separated from the power line. Moreover,
all connection cables must be disconnected in
order to prevent contact to external voltages. At
last the rechargeable batteries must be re-
moved.

Figure 1: Front panel unit
The front panel unit is a compact unit which con-
tains and connects the subunits shown above.
The main CPU executes the firmware of the device
with all aspects like graphic user interface, display
control, presentation of measured values, commu-
nication with interfaces, etc. The main CPU stores
all device settings, detector data and also the re-
sults of system tests.

In case of exchanging the front panel unit all these
data have to be saved first and later on entered into
the new front panel unit by means of the service
software.
The main CPU contains also the real-time clock
and the associated back-up battery.

Figure 2: Measuring module
The measuring module is designed as an inde-
pendent unit and can be exchanged with another
one of the same connecting system.
It stores all relevant amplifier data like calibration
factors and zeroing results as well as calibration
factors for measuring high voltage. With older edi-
tions of the measuring module, only the internal HV
can be measured and monitored.
Since the results of the system tests are stored in
the main CPU, these data are however no more
comparable after a replacement of the measuring
module.

Figure 3: Main board
The main board contains the individual subunits for
generation and monitoring of the supply voltages as
well as for charging the rechargeable batteries. It
fulfills connection functions beside that. Its name
originates from its physical size and implies in no
way, that it houses the main CPU.
The calibration factors for measuring of the supply
voltage are stored in the main board.
The results of the voltage monitoring can be read
out via service e-mail. It is not necessary to execute
measurements inside the device.

Service Software
10 D776.133.0/1
6 Service Software
The service software has to fulfill three tasks:
−Backup of the device settings as well as the
detector data base to a connected PC
−Update of the device firmware
−Restore of the device settings as well as the
detector data base
If a firmware update from PTW-Freiburg is released
for the UNIDOSwebline, the user can update the firm-
ware version on the newest version by means of
this software.
The software uses exclusively the RS232 interface
for communications.
A firmware update over the Ethernet interface is not
possible.
The software will probably be available in June
2006.
