i.e. the outputs will 'track' each other. Tracking will be maintained until one of the outputs reaches
the range limit, at which time each further Jog step will cause the buzzer to sound for that output
(but with the output remaining at the range limit) whilst the in-range output continues to change,
i.e. 'tracking' ceases and the outputs converge with each further step. If the increment/decrement
is reversed the new (smaller) difference between the outputs is maintained until one output
reaches the range limit in the other direction.
If Link mode is exited whilst Jog is selected, Jog continues to be active on the selected output.
Store and Recall
In Link mode a further 10 non-volatile memories are available which are quite separate from the
10 memories for each output in independent mode. The parameters stored are Range, Voltage,
Current Limit, OVP and OCP. Operation in Link mode is exactly as described in the Store, Recall
and Delete paragraphs of the Main Outputs section; the display messages described in these
sections appear in both displays when Link mode is selected.
OVP, OCP and Sense
OVP, OCP and Sense can only be set when either channel is independently selected. The
settings are maintained when Link mode is selected; OVP and OCP can be saved as part of a
Link mode set-up but the Sense setting cannot. If an attempt is made to change OVP, OCP or
Sense whilst in Link mode the display of Output 1 will flash
SELCt 1or2
to remind the user
that these parameters must be set independently for each channel. Press ESCAPE to cancel the
flashing display, assign control to the appropriate channel using the
CONTROL
1 or 2 keys
and set OVP, OCP, or Sense as described for the individual outputs.
Output Power
Pressing SHIFT, V x A causes the output power of both outputs to be displayed simultaneously in
their respective displays (V x A in the voltage display,
UA
in the current display) exactly as
described for independent operation.
Extra Functions
The # functions described in the Extra Functions paragraph of the Main Outputs section can also
be set when the instrument is in Link mode; both displays will show
HASH No.
_
after pressing
SHIFT, #. Any # function set in this way will of course be the same for both outputs. However,
the # functions can be different for each output if they are separately set whilst in independent
mode and the function selection will be maintained for each output even when the outputs are in
Link mode.
Bus Type and Address/Baud Rate
The Bus Type, Address and Baud Rate can only be selected when control is assigned to Output
2. The Output 2 display is used to show the parameters being set, exactly as described for
independent operation. If an attempt is made to set these parameters in Links mode, or with
Output 1 selected, the display of Output 1 flashes
SELCt P.U._2
as a prompt to select
Output 2. Press Escape to clear the display prompt (or wait for it to time out), then select
Output 2.
Main Outputs – Copy Function
The principle settings of Output 1 can be copied to Output 2 using the Copy function, irrespective
of the
CONTROL
mode (1, 2 or LINK) currently selected. The parameters copied are Range,
Voltage, Current Limit, OVP and OCP; the status of Sense, ON/OFF, Jog and the Store contents
are not copied.
Pressing SHIFT, COPY 1>2 causes the Voltage, Current and Range settings of Output 1 to
appear on the displays of Output 2 in flashing mode; the OK key also flashes. Pressing OK
confirms and implements the Copy operation; pressing ESCAPE at that point abandons the
operation.
