The test runs automatically and lasts ca. 3 min. During this time various measurement
results appear in the display, but these should be ignored. If the test discovers results
which lie outside the specified tolerance zones, the number of deviations found ap-
pears following completion of the test. If all results of the test are within the specified
tolerance zones, the following appears:
err: 0

5.4.9 Initialize data memory
This diagnostic step can be used to write default values to the instru-
ment parameters using the keypad and thus switch the instrument to
the original condition. This measure is important with the following two
points:
The setting of certain instrument parameters such as the locking of
keys is possible only via RS232, i.e. with the aid of a PC. If such
instrument parameters are set and no PC is available to cancel the
settings, full use can not be made of the instrument.
In rare cases, it is possible that major interference signals such as line
spikes and lightning can have an adverse influence on the contents of
the data memory. If the contents of the data memory are undefined,
this may lead to a system crash.
With the initialization step, default values can be written into parts of the
data memory (EEPROM). Although the adjustment data are retained,
the initialization should be performed only if necessary as the stored
user data (etc.) are deleted.
• Prepare instrument for diagnostic test (see section 5.4.2).
• If need be, press <9> key repeatedly until
