I tried this on my E4419. Sending the SYST:loc command generates an error -113, Undefined header. In other words it does not recognise the SYSTEM:LOCAL command. This is a bug in the E4419.
The solution would be to send the EXECUTE LOCAL transaction in a VEE direct I/O box. This does what you want and sets the box into local mode.

Hi all,
Having trouble executing the 'syst:loc' command on an E4419 Power meter to
make it 'local'.
this sounds so simple, but it just ain't happening.. it just sits there in
remote - no error or anything...
any ideas anyone or anyone seen this before...perhaps you have an E4418/9
sitting there you could just try....
Any help greatly appreciated.
Alex Barrett...
