Updating the rmware
The rmware developed for the instrument has been extensively tested and found to be stable and
reliable in use, however as with all software, unanticipated behavior may occur requiring correction, or
improvements with additional features and functionality may be released from time-to-time. The rmware in
the instrument incorporates its own ‘bootloader’ program which allows it to install updated rmware revisions
as and when the factory makes this available.
A small utility program needs to be installed on the PC which will be used to download the new rmware le
(V-TEST IIxxx.hex) to the instrument. This is a third party software developed by MikroElektronika* for this
purpose (refer to Figure 3).

Updating the rmware in the instrument is a complicated process and should only be undertaken
if absolutely necessary and where the user feels he has sucient capability. Incorrectly following
the steps provided, or prematurely terminating the update once started, may leave instrument in a
locked-up state, and require return to the factory.
If the user is unable to perform this update, please contact our technical support department for
