that was in use when the program was stored (RS232 or
USB etc). Alternatively, it is more common for the
communications interface to be associated with the
instrument rather than a stored program. There is a
selectable option in the REMOTE menu to enable the ‘recall
with program’. If this is ‘off’ then recalling the program will
not change the communications interface.
All file directory information can be displayed by pressing
the PROG key and then the TABLE button. This will allow
all the information to be displayed as a table and show
what the internal file directory contains. (Pressing the
TABLE button again exits the directory).
Datalog can be stored directly onto a USB memory stick
(maximum memory size 2GB) or logged to RAM and stored
subsequently. The data then can be recalled for viewing or
to download to a PC for further analysis.
Measurement results can be stored in one of 20 locations.
Press REAL TIME to hold the results, press PROG and
select memory = results. Each location holds the entire set
of computed results for all the phases no matter what
phase is on the display. Oscilloscope and harmonic series
data can also be stored but these take 3 contiguous
locations each because of a large amount of data. In each
case the full instrument set up is stored with the data and
recalled so that measurements may easily be repeated and
verified.
When using a large capacity (maximum memory size 2GB)
or slow USB memory device, all the data may not be
transferred within the transfer time window. If this
happens it will be recognised, and a display caption
appears to prompt the user to ‘press any key’ to terminate
the transfer when completed.
