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.
Press the
MODE/CLEAR SMOOTH
key to set one of the following test voltages: 250V, 500V,
1000V, 2500V, 5000V
6.
Insert the measuring leads into the relevant input leads of the instrument -Rx, +Rx and
GUARD, if necessary (see § 4.5 and Fig. 4)
CAUTION
Make sure that there is no voltage at the ends of the measuring points before
connecting 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 acoustic signal every second
and the display shows a screen similar to
that reported here to the side, which
contains:
The FIX selected mode
The bargraph proportional to the
measured resistance value
The numerical indication of the
measured resistance
The applied 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 time elapsed or remaining (if a test has been set)
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 if the duration of the test has been preset
The two "flash" symbols to indicate a dangerous voltage
The message "
MEASURING...
"
