Alternatively, logging can be left running and will
stop automatically a short while after the memory
becomes full.
The number of results which can be logged is
about 300, after which the message ‘full’ will be
flashed on the display for a few minutes. The
instrument will then shut down.
Other considerations
Note that the batteries may not last through the
whole logging session, depending on their
condition and on the log interval which has been
set. If the batteries should fail, any results already
logged will be retained. Note also, that if the
TEST
button has been set for non-latching operation,
this will be temporarily overridden during logging
of insulation results, giving a press-to-start, press-
to-stop action. The
TEST button’s mode of
operation will return to its original setting after the
logging session has finished.
Viewing logged data.
Logged results can only be retrieved via the
instrument’s RS232 port, using a PC connected via
a serial cable. The disk supplied with the
instrument carries a programme capable of
handling the data. The method is similar to that for
‘downloading’ stored results. For further
information see the section entitled “Download to
PC”. Note that on millivolts d.c. and milliamps d.c.
measurements, the frequency result is always set
to zero. On millivolts a.c. and milliamps a.c.
measurements, the frequency result is set to zero if
the frequency could not be measured.
Setup Modes
Serial Printer configuration
The printer should be set to 9600 baud, 8 bit data,
no parity and 1 stop bit. This instrument uses a
special isolated serial interface which is powered
from the PC or printer. In the unlikely event that
your PC or printer is not able to power the
interface, it will be necessary to provide an
additional supply. Contact
Megger Product
Support for details.
