range is from -31 to + 31%. If the reference clock is «fast», decrease the value, and if the
clock is «slow», increase this value. The parameter value tuning range corresponds to
clock rate from -2.75 min/month to + 5.5 min/month.
4.7.8. Reference Clock Date Setting
The parameter is intended for setting or tuning of the reference clock date. To set the
date, select the corresponding parameter using « ► » . Set the current date by « » and
« » keys. To set the month, press « ► » . Set the value by « » and « » . To set the year,
press « ► » . Set the value by « » and « ». Press « ◄ » key three times to return to the

4.7.11. Measurement Mode Quick Access
There are two values of the parameter available: on/off . When the parameter is set to
on , after switching, automatic testing, calibration matrices loading, and the frequency table
integrity check, the last previously used measurement mode will be enabled. When this
parameter is set to
off , after switching, automatic testing, calibration matrices loading, and
the frequency table integrity check, the Analyzer will show the main menu.
4.8. Identification Data Readout
Identification data readout program is intended for determining the serial numbers of the
modules of the Analyzer, their modifications and software versions. The icon
corresponds to this mode. See figure 4.35:
