Real time output parameters
Electrical output parameters (mA, V, and W) will be displayed in real time in a bar at the bottom of the
screen. The method parameter being held constant will be in highlighted font.
Crossover indicator
When electrical output is limited by a non-constant method parameter or by a power supply output
maximum, the automatic crossover feature is activated. The crossover icon ( ) will then be displayed
to the right of the new limiting parameter and that parameter will be in highlighted font.
As an example: If the method uses constant voltage of 200 V, but the power supply reaches 500 mA
(the power supply maximum) before 200 V is reached, the power supply will automatically switch to
a constant current of 500 mA with the voltage floating. If at some point conditions of the run change
(resistance increases and current drops) such that 200 V can be delivered with less than the power
supply maximum current (500 mA), the power supply will automatically revert back to the set method
constant parameter (200 V in this case) and the crossover icon will no longer be displayed. Figure 12
shows a run with crossover to mA and current limited to 40 mA. For additional details, see Appendix A,
“Troubleshooting”.
Stop and Pause buttons
The run can be stopped or temporarily paused by touching
Stop
or
Pause
. The method can be edited
when paused.
Right navigation arrow
Touch this arrow to display the
Method Settings
screen (Figure 12). This screen shows parameter
settings for the step currently being run. From this screen, touch the
left
arrow to return to the
Run
screen.
Method Settings screen features
The
Method Settings
screen (see Figure 12) displays voltage, current, power, and run time for the
method. Time is shown in hours : minutes format. If the method has more than one step, there will be
a separate method screen for each step. Use the
right
and
left
arrows to move between screens for
individual steps.
Note:
Method settings are not real-time numbers. They do not change during the run. Real-time run
parameters are shown on the
Run
screen.
