PC++
To enable configuration via + software the SVAN 971 should be connected
to the PC with this software installed.
Since the USB connection is used for powering the SVAN 971 when it is installed in
the SV 271, the user should:
1. disconnect station USB cable from the SVAN 971 and
2. connect another USB cable to the SVAN 971 and the PC.
It is not necessary to disconnect the input connector of the instrument and remove the
instrument from the station slot. There is no need also to install internal batteries to the
SVAN 971 as it will be powered from PC via USB.
To start working with both programs you should turn the SVAN 971 on and run the
program, which automatically install USB connection with the instrument.
Note: USB connection between SVAN 971 and PC can be established only
if USB driver for SVANTEK instruments had been previously installed on the
PC. USB driver can be downloaded from
