6. SAFETY TEST FUNCTIONS

6.1. LOWΩ: CONTINUITY TEST WITH 200mA TEST CURRENT
The measurement is taken according to EN 61557-2 and VDE 0413 part 4.
ν
WARNING:
Turn the rotary knob to the LOWΩ position.
This key allows the operator to select one of the following measuring modes:
AUTO mode (the instrument carries out two measurements with reversed
polarity and displays their average value). This mode is recommended
for the continuity test.
RT+ mode (measurement with positive polarity and the ability to set the
duration time of the test). In this case the operator can set a measuring
time long enough to permit them to move the protective conductors while
the instrument is carrying out the test so as to detect any bad
connections.
RT- mode (measurement with negative polarity and the ability to set 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 as to detect any bad connection.
This key permits the operator to perform a calibration (compensation for the
resistance of the cables used for the measurement).
N.B. If the resistance is lower than 5Ω (including the resistance of the calibration) the
continuity test is executed by the instrument with a test current higher than 200mA.
Before carrying out the continuity test be sure that there is no
voltage at the ends of the conductor under test.
