TH 10.211/8.02 - 12/97
52: 01 E53 03.07.96 13:00 List error log
Outputs the 10 most recent error messages or warnings
together with date and time.
Through the value push-buttons it is possible to call up
the 10 most recent messages.
Since the number of digits of the text panel (4/2) is limi-
ted, only the number code 1 ... 99 of the error messages
and warnings is indicated and error messages are mar-
ked by and „E“ whereas warnings are marked by a „W“.
A description for each error code number is given in the
list of Chapter 4.2.
53: Status to RS232 <Enter> Output status report
through RS 232
The status report provides important information on the
internal conditions of the UL 200 for service work.
The status report may be output through a printer which
is connected to the SERIAL connection (2/10) on the
UL 200 or by using a computer running a terminal pro-
gram (Windows TERMINAL, for example). How to
connect a printer or a PC is described in the description
of the interface SB 10.211.
54: Scan To Rec <Enter> Output mass spectrum
Via the chart recorder output (2/11) it is possible to out-
put a mass spectrum for masses M2, M3 and M4.
Thus proper functioning of the detection system can be
checked. You may connect either an X(t) or an XY chart
recorder.
In order to be able to output the mass spectrum, you
must first enter the second password (menu item 50) and
switch of the automatic facility (menu item 70).
The preamplifier voltage is output through channel 1
[(2/11) pin 1 to pin 2]. The preamplifier voltage is output
is a logarithmic manner.
The mass spectrum can be run for each of the preampli-
fier’s ranges (service menu 75).
The anode voltage which is required for selection of the
mass is output through channel 2 [(2/11) pin 4 to pin 3]
at a ratio of 1:100.The range of anode voltages which is
swept ranges from 300 V to 1000 V (3 ... 10 V at the chart
recorder output). Next, the anode voltage which has
been stored for the selected mass is output.
The entire mass scan takes about 70 s.

Depending on the strength of the magnetic field of the
built-in magnets, the peaks for the preamplifier voltages
must fall into the following ranges:
M2: 785 ... 995 V
M3: 510 ... 670 V
M4: 390 ... 520 V
How to proceed
Channel 1 is connected to the Y-input of the XY chart
recorder or the voltage input of the X(t) chart recorder.
When using an XY chart recorder you must also connect
channel 2 to the X-input. Switch the chart recorder on
and start the mass scan by pressing the ENTER push-
button (3/8).When evaluating an X(t) recording you must
take note of the fact that the anode voltage is increased
by 5 V every 480 ms.
