Operation
6. On pressing the START key, the automatic test sequence is initiated, and the voltage is
displayed ramping up to the withstand voltage level. Pressing the right hand key labelled STOP
will abort the test, and return to the original display. On successfully attaining the upper voltage
limit, the display will appear similar to figure 10. Elapsing time (in seconds) is indicated, until 1
minute has elapsed, or breakdown has occurred.
7. The sequence of events now depends on the results of the first test. If the test was successful
no further testing takes place. The display appears similar to figure 21a.

8. If the first test fails the requirements of BS 5730a, two further consecutive successful tests
mustbe performed. Prior to the repeat withstand voltage application, a 1 minute stir followed by a
1 minute stand period is automatically performed.
9. The second application of the withstand voltage will automatically occur next, with the sequence
repeating step (6) above. The display will indicate the actual test number in progress.
10. The sequence of events now depends on the result of the second test. If the second test is
unsuccessful, no further testing takes place.The display appears similar to figure 21b.
Pressing the left hand key labelled VIEW changes the top half of the display to show the break
down voltages, together with the pass limit voltage. The display appears similar to figure 22.
If the automatic print out option is pre-selected, the results will be automatically printed. If not,
press the centre key labelled PRINT to obtain a print out of the results. When the printer is in
operation, the display shows 'PLEASE WAIT PRINTING'.
11. If the second test was successful, a third test must be performed. Prior to the repeat withstand
voltage application, a 1 minute stir followed by a 1 minute stand period is automatically
performed.
12. A third application of the withstand voltage will occur next, with the sequence repeating step (9)
above. The display indicates the actual test number in progress.
13. If the third test was successful, the display will appear similar to figure 21a. An unsuccessful third
test will prompt a display similar to figure 21b, and no further testing takes place.
