Tescom ACT6000 - 9. Advanced Software Activation; 0. THRESHOLD LIMITS SETUP; Transmission Tests Limits (DELT and SELT mode)

ACT6000 User Guide – January 2021 Page 50 of 52
9. Advanced Software Activation to install the optional software module.
Loaded on the Pen-Drive the software key (i.e. for ASW-1/II), connecting the Pen-Drive to
the related USB ports, selecting this menu the software will be automatically activated.
0. THRESHOLD LIMITS SETUP
This menu allows to verify or configure the
transmissive threshold limits for the SELT or
DELT measurements.
Any limit can be modified according to (when
necessary) the ranges of the of the specific test
functions declared on the technical
specifications.
Pushing the F5 “Edit” key a window appears,
then by the key and the ◄ ► arrows it
is possible to modify every parameter value.
If necessary to update the “Limits data-base” with the new one externally re-edited, i.e. by
the specific ACT6000 PC Utility (compatible with Windows XP and downloadable from
https://tescomusa.com/pages/act6000-applications), push the F4 “Import” key selecting 1
from PC or 2 from USB Pen-drive.
If desired to export the present limitdat.csv file it is enough to push the key and
select 1 from PC or 2 from USB Pen-drive.
