frequency reference can come from a digital preset reference (

n21

n08

) or the

digital operator pot (

n07

).

Remote -

Run and stop functions are determined by parameter

n02

. The frequency reference is

determined by parameter

n03

.

Switching between local and remote is accomplished either by the LO/RE LED on the digital operator
or by the use of a multi-function input terminal programmed to data “
