2. GENERAL DESCRIPTION

2.1. INTRODUCTION

The instrument purchased by You, if used in compliance with the instructions given in this
manual, will guarantee accurate and reliable safety measures also in single phase and three
phase photovoltaic plants.

2.2. INSTRUMENT OPERATION

The instrument can perform following tests (compatibly with the characteristics described
in the table above):
 LOW
 M
 RCD

 Ra
 123
Continuity test of earth conductors, protective conductors and equipotential
conductors with test current higher than 200mA and open circuit voltage
between 4V and 24V.
Insulation resistance measurement with a direct test voltage of 50V, 100V,
250V, 500V or 1000V.
Measurement of following parameters on A-type (
general and/or selective differential switches: tripping time, tripping current,
contact voltage (Ut), total earth resistance (RA).
Measurement of line impedance and fault loop impedance with
calculation of the assumed fault current.
Measurement of total earth resistance with 15mA without causing the
differential protections' tripping.
Indication of the phase sequence.
