Improvements Introduced with V 2.0 Firmware
New Measurement Features:
1.
The ability to perform “broadband” logging measurements in a
selected octave or third octave band.
This allows users of narrow band instruments to restrict broad-
band measurement to any available frequency band, and log data
for all selected broadband parameters.
New Timer Features - CEL-480 only
2.
A seventh set of Delay Timers.
This allows a different set of timers to be selected for each day
of the week.
3.
A Repeat function for the Delay Timer.
This allows a week’s settings to be used up to 999 times.
Improved Display Features:
4.
The number of tests the instrument has to perform is shown
during the self test routine so the user knows when it has got to
the end with no problems.
5.
An indication of the last used setup during the startup procedure.
6.
An additional line on menus showing the selection number and
the total number of choices available.
During a run, this line is inhibited to indicate that the items are not
changeable.
7.
The option to store data or re-start the measurement when
is pressed at the end of each run.
8.
Storage and print out of the last TWO sets of calibration data on
the default hard copy.
This allows the pre- and post-measurement calibrations to be
recorded.
9.
The ability for scrolling to wrap-round when inspecting period data
stored on a CEL- 480.
10.
The spectrum is left on screen when a narrow band frequency
scan finishes so the user can inspect it without having to recall it
from memory.
11.
The ability to store Histogram data in the meter from the SETUP/
FUNCTIONS menu.
