While measuring, it is also possible to display the leakage current, the DAR
(Dielectric Absorption Ratio if test duration > 1 minute), the PI (Polarization Index if
test duration > 10 minutes) which cyclically show when pressing the arrow keys (see
§12.1)
If no measuring time was set when setting the parameters or if you want to stop the

11a. Once measurement is complete and
any capacitance has been discharged,
the instrument shows:
• The
value
insulation resistance
• The value of the generated voltage
• The duration of the test
• If the measured resistance value is
between the (MIN - MAX) limits
previously
shows OK and gives a double
acoustic signal (see § 5.3.1)
11b. Once measurement is complete and
any capacitance has been discharged,
the instrument shows:
• The
value
insulation resistance
• The value of the generated voltage
• The duration of the test
• If the measured resistance value is
not between the (MIN - MAX) limits
previously
shows NOT OK, the alarm bell and
gives a long acoustic signal (see §
5.3.1)
12. Once measurement is complete, it is also possible to display the leakage current, the
DAR (Dielectric Absorption Ratio), the PI (Polarization Index) and the capacitance
which cyclically show when pressing the arrow keys (see § 12.1)
• If the measured resistance value < 5,0M , the screen displaying the
capacitance shows three hyphens "---", to indicate that it was impossible to
measure the capacitance, and the symbol
• If, when scrolling the results obtained, the capacitance value is > 1nF, it is
recommended to repeat the measurement by activating the SMOOTH
function (see § 5.5)
