Note:
When creating test sequences, use the following guidelines to prevent damage
to the unit:
Estimate the AC frequency and peak-to-peak voltage, V(PK-PK) of
the desired test sequence.
Convert the estimated V(PK-PK) to a % of maximum output
voltage (e.g., if V(PK-PK) is 10V and maximum voltage of the
supply is 100V, then %V(PK-PK) = 10%)
Verify that the frequency and %V(PK-PK) do not exceed the
values below:
Frequency
% V(PK-PK)
10Hz
25%
50Hz
5.0%
100Hz
2.5%
150Hz
1.67%
200Hz
1.25%
Another consideration is the actual rise and fall capabilities of the
output of the supply. Although damage will not occur, the shape of
the output waveform will be affected by the rise/fall times in
relation to programmed sequence settings. These vary widely
depending on the load conditions; contact the factory for further
information.
.
Note:
Contact the factory for detailed information if the desired waveform
exceeds the recommended limits as discussed.
To change the test sequence, use the NavPad up/down to scroll through the
test list. From this menu the user may Start (F1), Single Step (F2), Program
(F3) or Delete (F4) a sequence.
START: press F1 from the main Sequence Menu to start and run a test
sequence. The display will show the test sequence name and step number
(e.g., TEST01-12, Sequence TEST01, step 12). It will also indicate the current
operation being executed (see Section 3.8.4.3, Operations) and will display
voltage, current, OVP, power and time remaining for that step. The time
format is hhhh:mm:ss:sss (last three digits are milliseconds).
User may pause or stop the test at any time by pressing either F3 to pause or
F4 to stop the sequence. The output will pause or stop in the same state as
the test step was when the key was pressed. Pressing F3 (Resume) restarts
the sequence from the beginning of the same step. (
Note:
For steps with
voltage or current ramps, the step will resume at the beginning of the ramp and
not at the point at which the ramp was paused.) Pressing F4 (Stop) to stop the
sequence returns the display to the main Sequence Menu.
SINGLE STEP: press F2 from the main Sequence Menu to single step
through a test sequence. The display will show the test sequence name and
