4.
By pressing the arrow keys, the
instrument shows a screen similar to that
reported here to the side, which contains
the value of the input voltage.
5.
Make sure that the set test voltage is the desired one. Should it not be the case, please refer
to § 4.9.1 to change it
6.
Insert the measuring leads into the relevant input leads of the instrument -Rx, +Rx and
GUARD, if necessary (see § 4.5 and Fig.5)
CAUTION
Make sure that there is no voltage at the ends of the measuring points before
connec ng them to the measuring leads.
7.
Connect the alligator clips to the part of the system to be tested.
8.
Press the START/STOP key to perform measurement
CAUTION
The display shows the message “
Measuring…
” which indicates that the instrument is
performing the measurement. During this whole phase:
Do not disconnect the measuring leads of the instrument from the conductor
being tested; the conductor could remain live at a dangerous voltage because of
possible stray capacitances in the circuit tested
Never insert the power cord into the Mains socket
9.
During measurement, the instrument gives a
short acous c signal every second and the
display shows a screen similar to that
reported here to the side, which contains:
The ADJUST func on selected
The bar graph propor onal to the
measured resistance value
The
numerical
indica on
of
the
measured resistance
The actual test voltage
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 test me elapsed or remaining (if a test has been set)
The plug symbol (if the instrument is supplied from the mains)
The ba ery symbol steadily illuminated or flashing (if ba eri es are flat or are being
recharged)
The mer symbol if the dura on of the test has been preset
The two “flash” symbols to indicate a dangerous voltage
The message “
MEASURING…
