Shuttle Knob
The shuttle knob or rotary digital encoder is active only in MANUAL and DC modes of
operation. When the OUTPUT is ON, the shuttle can be used to adjust voltage or frequency.
To adjust frequency with the shuttle, the Frequency measurement must be selected in the
measurement screen. If not, the shuttle will always adjust the voltage setting when turned.
Turn clock wise to increment the set value, turn counter clockwise to decrement the set
point.
When the instrument is in an idle state (OUTPUT OFF), it can also be used to edit the “
Hi-
Lmt
”. To adjust the “
Hi-Lmt
” with the shuttle knob the meter selection must be on Hi-Lmt.
Note:
If the front panel is locked (LOCK is set to ON), the shuttle knob is disabled.
