START/SET key is pressed at this point, a further confirma-
tion message "Delete Memory, sure?" is shown, which has
to be confirmed by pressing the START/SET key once again.
Then, the report data in memory are deleted.

8.6 Keeping Data in Memory

When the cable or storage media is unplugged, a "Delete
Memory" message is displayed. Press the STOP/RESET key
to keep the current report data in memory. They can then
be printed off once again.
Make a habit of handling the internal storage as
described at the beginning of Sect. 8, to maintain
data integrity and avoid any inadvertent deletion
Important
of the reports in memory.

Dedicated Welding Unit Information

9.1 Displaying Characteristics of the Welding Unit

The key technical information on the welding unit itself is
displayed by pressing the ð key at the "Enter Fitting Code"
screen. They are the software version, the serial number
of the unit, the date of the next scheduled maintenance,
and the number of currently available, unused reports. To
quit this screen, press the STOP/RESET key.
If the scheduled service is overdue, a service due message
appears on the screen as soon as the unit is plugged into
the mains or generator power supply. This message has to
be acknowledged by pressing START/SET.

9.2 Measuring Resistance

When the START/SET key was pressed to initiate a welding
process, the resistance value of the fitting is measured and
compared to the value entered as part of the read fitting
code. If the gap between the two values is smaller than
the acceptable tolerance given in the code, the welding
process starts. If the gap is greater than the preset tol-
erance, the welding unit aborts welding and displays a
"Resistance Error" message. Furthermore, it displays the
actual resistance value measured for the connected fitting.
The reason for a resistance error may be poorly contacting
and/or worn connection terminals. Therefore, if this error
occurs, check them for proper fit and, if worn, replace
them with new ones.
