CAUTION
For recordings (ANALYSIS and AUX function) use ALWAYS the external
power supply adapter (optional code A0050) even the instrument allows the
operator to perform a recording using internal batteries. If during a recording
the external power supply adapter is de-energised, the instrument will
continue the recording using the internal battery power until the batteries
are exhausted (the data stored up to the point the instrument shuts down
won’t get lost). For this we recommend you ALWAYS insert a new set of
batteries before a long recording.
The instrument uses sophisticated algorithms to prolong the battery life. Particularly:
The instrument switches OFF the backlight Automatically after 5 seconds.
If the instrument is displaying in real time (and the external power supply adapter is not
connected), after about 5 minutes from the last key pressure or switch rotation the
instrument turns off automatically ("AUTOPOWER OFF" procedure).
If the instrument is recording or is measuring energy (and the external power supply is
not connected), after about 5 minutes from the last key pressure or switch rotation the
instrument starts a special procedure to save the batteries ("ECONOMY MODE"): the
instrument keeps recording but the display is turned off.
3.3. CALIBRATION
The instrument fulfils the technical specifications listed in this manual. The performance of
the specifications are guaranteed for one year.
3.4. STORAGE
In order to grant the accuracy of the measurements, after a period of storage in extreme
environmental conditions, wait for the time necessary so that the apparatus is back to
normal measuring conditions (see environmental specifications listed in paragraph 14.4).

6. SAFETY TEST FUNCTIONS
6.1. LOWΩ: CONTINUITY TEST WITH 200mA TEST CURRENT
The measurement is effected according to EN 61557-2 and VDE 0413 part 4.
Before carrying out the continuity test make sure that there is no voltage at
the ends of the conductor under test.
Turn the switch on LOWΩ position.
This key permits to select one of the following measuring modes:
Mode "AUTO" (the instrument carries out two measurements with
reversed polarity and displays their average value). This mode is
recommended for the continuity test.
Mode "RT+" (measurement with positive polarity and possibility of setting
the duration time of the test). In this case the operator can set a
measuring time long enough to permit him to move the protective
conductors while the instrument is carrying out the test so detecting any
bad connection.
Mode "RT-" (measurement with negative polarity and possibility of setting
the duration time of the test). In this case the operator can set a
measuring time long enough to permit him to move the protective
conductors while the instrument is carrying out the test so detecting any
bad connection.
This key permits to execute the "CAL" mode (compensation of the resistance
of the cables used for the measurement).

TEST LEADS Before each measurement always make sure that
the calibration is referred to the cables in use.
During a continuity test, if the resistance value free
of calibration (that is the resistance value less the
calibration offset value) is negative, the symbols

value stored in the instrument memory is not
referred to the cable in use, therefore a new

and VDE 0413 part 6.
CAUTION
The automatic check of the RCD features causes the tripping of the RCD itself.
Therefore check that all devices connected downstream the RCD under
test are not damaged by power off. Possibly disconnect all the loads
connected downstream the RCD as they could add additional leakage currents
to the instrument ones and so making the test results void.
Turn the switch on RCD position:
The F1 key permits to select one of the following measuring mode (which can
be shown cyclically when pressing the key):
Mode "AUTO" (the instrument effects the test automatically with a
leakage current equal to half, once and five times the value of the rated
current set). Recommended test.
Mode "x ½" (the instrument effects the test with a leakage current equal
to half the value of the rated current set).
Mode "x 1" (the instrument effects the test with a leakage current equal
to once the value of the rated current set ).
Mode "x 2" (the instrument effects the test with a leakage current equal
to twice the value of the rated current set).
Mode "x 5" (the instrument effects the test with a leakage current equal
to five times the value of the rated current)
Mode " " (the instrument effects the test with a ramp growing leakage
current. Use this test to measure the tripping current).
Mode "R
" (the instrument effects the test with a leakage current

equal to half the value of the selected rated current and calculates the
contact voltage as well as the Ra earth resistance).

Note if the test is effected on general RCDs the symbol n is NOT displayed
Note according to EN61008 the test on the selective RCDs requires an interval between
the tests of 60 seconds (30 seconds in case of tests at ½ I∆n). A timer is displayed
indicating the waiting time for each step.
Example: Test with AUTO mode on a RCD with I∆n=30mA.
a) the instrument effects the test at ½ I∆n 0°. The RCD must not
trip.
b) The instrument effects the test at ½ I∆n 180°. The RCD must
not trip. For a Selective RCD a 30 seconds timer starts
before executing next test.
c) The instrument effects the test at I∆n 0°. If the RCD passed
the test, it must trip and the instrument shows the message
"RESUME RCD". The operator shall resume the RCD. For a
Selective RCD a 60 seconds timer starts before executing
next test.
d) The instrument effects the test at I∆n 180°. Follow the same
procedure as described under c).
e) The instrument effects the test at 5I∆n 0°. Follow the same
procedure as described under c).
f) The instrument effects the test at 5I∆n 180°. Follow the same
