CAUTION

Upon pressing the GO/STOP key, different error messages can be displayed

by the instrument (see § 6.6) and, therefore, the test cannot be started. Check

and eliminate, if possible, the problem causing the error message before going

on with the test.

9. Press GO/STOP to start the test. In case no erro

conditions occur, the instrument displays the message

“Measuring…” and the measure of open-circuit voltage

between the terminals P and N and of short-circuit current

(for Isc values 10A).

10. When Voc and Isc measurements are complete, the

message “OK” is shown in case the result of the test is

positive (measured values within the tolerances set on the

instrument)

11. With insulation measurement selected, the instrument

goes on with the test keeping terminals P and N short-

circuited, and carrying out the test between this point and

terminal E for the time necessary to obtain a steady value.

12. The value of insulation resistance is shown in field “Ri” and

the message “OK” appears in case the result of the test is

positive (measured value higher than the minimum limit

value set on the instrument).
