Description of the pump test

Once the test has been started and automatic mode
has been activated, the waiting and measuring times
begin as soon as the specified setpoints are reached.
After the times have elapsed, the software automati-
cally switches to the next test step and saves the test
results in the test protocol.
When the last test step is reached and the measuring
times have elapsed, the test bench comes to a stop and
the test is complete.
Press <F12> to call up the test protocol.
