protected, excessive voltage could cause damage.
1.3. AFTER USE
When measurements are complete, turn off the instrument by pressing and holding the
ON/OFF key for some seconds.
If the instrument is not to be used for a long time, remove the batteries and follow the
instructions given in § 9.2.
DEFINITION OF MEASUREMENT (OVERVOLTAGE) CATEGORY
Standard “IEC/EN61010-1: Safety requirements for electrical equipment for measurement, control and laboratory use, Part 1: General requirements” defines what measurement category, commonly called overvoltage category, is. § 6.7.4: Measured circuits, reads:
Circuits are divided into the following measurement categories: Measurement category IV is for measurements performed at the source of the low-
voltage installation
Examples are electricity meters and measurements on primary overcurrent protection devices and ripple control units.
Measurement category III is for measurements performed inside buildings.
Examples are measurements on distribution boards, circuit breakers, wiring, including cables, bus-bars, junction boxes, switches, socket-outlets in the fixed installation, and equipment for industrial use and some other equipment, for example, stationary motors with permanent connection to fixed installation.
Measurement category II is for measurements performed on circuits directly
connected to the low-voltage installation
Examples are measurements on household appliances, portable tools and similar equipment
Measurement category I is for measurements performed on circuits not directly
connected to MAINS.
Examples are measurements on circuits not derived from MAINS, and specially protected (internal) MAINS-derived circuits. In the latter case, transient stresses are variable; for that reason, the standard requires that the transient withstand capability of the equipment is made known to the user.

6. OPERATING INSTRUCTIONS
6.1. LOW: CONTINUITY OF PROTECTIVE CONDUCTORS WITH 200mA
Measurement is carried out in compliance with standard IEC/EN61557-4.
Before carrying out the continuity test, make sure there is no voltage at the ends of the conductor to be analyzed.
Turn the rotary switch to LOW.
With the F1 key it is possible to select one of the following measuring modes (which cyclically appear when pressing the key):
“AUTO” mode (the instrument carries out two measurements with
inverted polarity and displays their average value). Recommended mode for continuity test
“RT+” mode (measurement with positive polarity and with the possibility
of setting a duration time for testing). In this case, the operator may set a sufficiently long measuring time to be able to move the protective conductors while the instrument is carrying out the test, in order to find out a possible bad connection.
“RT-” mode (measurement with negative polarity and with the possibility
of setting a duration time for testing). In this case, the operator may set a sufficiently long measuring time to be able to move the protective conductors while the instrument is carrying out the test, in order to find out a possible bad connection.
With the F2 key it is possible to select the “CAL“ mode (compensation of the resistance of the cables used for measuring).
CAUTION
CAUTION
Continuity test is carried out by applying a current higher than 200mA in case resistance does not exceed 5 (including the measuring cables’ resistance saved as offset value in the instrument after carrying out the calibration procedure). For higher resistance values, the instrument carries out the test with a current lower than 200mA.

CAUTION
The instrument calibrates the measuring cables only if their resistance is
lower than 5
Before carrying out any measurement, always make sure that calibration
is referred to the cables currently used. In a continuity test, if the purified resistance value (i.e. the value of resistance minus the calibration offset value) is negative, the symbol “CAL” flashes on the display.
7. To delete the calibration parameter it is necessary to carry out a calibration
procedure with a lead resistance higher than 5 (e.g. with open leads). When carrying out a deletion, the symbol “- - -“ is shown on the display above the F2 key.

6.2. LOW10A: CONTINUITY OF PROTECTIVE CONDUCTORS WITH 10A
Measurement is carried out in compliance with standards IEC/EN60439-1. Measurement is carried out by voltammetric method with 4 wires. Therefore, the calculated
value is not influenced by the value of resistance of the measuring cables, so it is not necessary to carry out any preventive calibration of the cables used for measuring (unlike with function LOW).
CAUTION
Before carrying out the continuity test, make sure there is no voltage at the
ends of the conductor to be analyzed.
Measurement may be influenced by parallel impedance of additional
circuits or by transient currents. Make sure none of these parasite elements is present before measuring and always keep test cables
outstretched in order to prevent “coil effects”.
CAUTION
The instrument performs the test with a current 10A only if resistance is lower than approx. 0.45.

6.3. LOW10AE204: CONTINUITY 10A IN COMPLIANCE WITH IEC/EN60204­1:2006
Measurement is carried out in compliance with standard IEC/EN60204-1:2006, which states that measurement result must be compatible with the protective conductor’s length, section and material.
The instrument evaluates the limit threshold of measured resistance according to the following formula:
L
lim
R
S
in which: L = length in m of the protective conductors being tested, decided by the user
according to design calculations;
 S= section in mm2 of the protective conductor being tested;  = resistivity of copper set to the standard average value of 0.017mm2/m.
Measurement is carried out by voltammetric method with 4 wires. Therefore, the calculated value is not influenced by the value of resistance of the measuring cables, so it is not necessary to carry out any preventive calibration of the cables used for measuring (unlike with function LOW).
CAUTION
Before carrying out the continuity test, make sure there is no voltage at the
ends of the conductor to be analyzed.
Measurement may be influenced by parallel impedance of additional
circuits or by transient currents. Make sure none of these parasite elements is present before measuring and always keep test cables
outstretched in order to prevent “coil effects”.

With the F1 key it is possible to select one of the following measuring modes (which cyclically appear when pressing the key):
“P-N” mode (the instrument measures impedance between Phase
conductor and Neutral conductor and calculates the assumed Phase­Neutral short-circuit current. This test is usually carried out to evaluate if the breaking power of switches is higher than short-circuit current in the installation point).
“P-P” mode (the instrument measures impedance between two Phase
conductors and calculates the assumed Phase-Phase short-circuit current. This test is usually carried out to evaluate if the breaking power of switches is higher than short-circuit current in the installation point).
“P-PE” mode (the instrument measures the overall earth resistance and
calculates the assumed Phase-Earth short-circuit current. This test is usually carried out to evaluate the coordination of the protections against indirect contact by means of an automatic interruption of power supply and to measure the value of Earth resistance).
“RA” mode (the instrument measures the overall earth resistance and
calculates the assumed Phase-Earth short-circuit current. This test is usually carried out to evaluate the coordination of the protections against indirect contact by means of an automatic interruption of power supply and to measure the value of Earth resistance. This test has a lower resolution than “P-PE” test, but has the advantage that it can be carried out without making a possible residual current protection, installed upstreams of the measuring point, trip).
“ ” mode (the instrument detects phase sequence).
