During measurement, the instrument
gives a short acoustic signal every
second and the display shows a screen
similar to that reported here to the side,
which contains:
• The RAMP function selected
• The bar graph proportional to the
measured resistance value
• The numerical indication of the
measured resistance
• The segment relevant to the current ramp point, flashing
• The actual test voltage (relevant to the current ramp point)
• The symbol of the alarm bell (if the measured value is not within the set limits
and/or if the value of the test voltage is lower than the set nominal value)
• The value of the remaining test time (relevant to the current ramp point)
• The plug symbol (if the instrument is supplied from the mains)
• The battery symbol steadily illuminated or flashing (if batteries are flat or are
being recharged)
• The timer symbol
• The two "flash" symbols to indicate a dangerous voltage
• The message "MEASURING..."
While measuring, it is also possible to display the leakage current, the capacitance
the number N of the cycle the instrument is performing, which cyclically show when
pressing the arrow keys.

If you want to stop the test in advance before the set number N of cycles is reached,
press the START/STOP key.
10a. Once measurement is complete and
any capacitance has been discharged,
the instrument shows:
• The
value
insulation resistance
• The value of the actually generated
voltage V1
• The value of the time relevant to
parameter T1
• If the measured resistance value is
between the (MIN - MAX) limits
previously set, the instrument shows
OK and gives a double acoustic
signal (see § 5.4.1, § 5.4.2, § 5.4.3)
