2. GENERAL DESCRIPTION
Instrument EQUITEST 5071 carries out the following measurements:
 LOW:
Continuity test of protective conductors with test current of 200mA in
compliance with standard IEC/EN61557-4
 LOW10A:
Continuity test of protective conductors with test current of 10A in
compliance with standard IEC/EN60439-1
 LOW10AE60204: Continuity test of protective conductors with test current of 10A in
compliance with standard IEC/EN60204-1:2006.
 LOOP/Ra
: measurement of line impedance and fault loop impedance with
calculation of the assumed short-circuit current, also with high
resolution (0.1m
) with optional accessory IMP57 / measurement of
overall earth resistance without causing the differential protections’
tripping (function R
A
) / phase rotation.
3. PREPARATION FOR USE
3.1. INITIAL CHECKS
Before shipping, the instrument has been checked from an electric as well as mechanical
point of view. All possible precautions have been taken so that the instrument is delivered
undamaged.
However, we recommend rapidly checking it to detect any damage possibly suffered
during transport. In case anomalies are found, immediately contact the Dealer.
We also recommend checking that the packaging contains all components indicated in §
10.4. In case of discrepancy, please contact the Dealer. In case the instrument should be
returned, please follow the instructions given in § 11.
3.2. INSTRUMENT POWER SUPPLY
The instrument is supplied by six 1.5V alkaline batteries type LR6 AA AM3 MN 1500, not
included in the package. For battery installation, follow the instructions given in § 9.2.
CAUTION
 The instrument AUTOMATICALLY turns OFF display backlight after
approximately 5 seconds.
 In order to extend the battery life, in case battery voltage is too low, the
instrument deactivates display backlighting.
3.3. CALIBRATION
The instrument has the technical specifications described in this manual. Its performance
is guaranteed for 12 months from the date of purchase.
3.4. STORAGE
In order to guarantee precise measurement, after a long storage time under extreme
environmental conditions, wait for the instrument to come back to normal condition (see
§ 10.3)
