lows to carry out several kinds of insulation tests automatically, recording
all the results in its internal memory or printing them. That's why it is neces-
sary to define the tests properly, selecting its parameters before starting the
test:
•
Test voltage.
•
Equipment operation mode.
•
Minimum resistance limit, for the "Pass-fail test".
These three parameters shall be defined before starting the test. The test
voltage is the only parameter that can be modified during the test. The
*,.0 keys makes it possible to enter the different equipment program-
ming modes. The 7 (decrease) and 8 (increase) keys select the value.
