the “HOLD” function
1.4. AFTER USE
After use, turn off the instrument by pressing ON/OFF key for a few seconds.
If you expect not to use the instrument for a long time please keep to the storage
instructions described at § 3.3.
1.5. MEASURING (OVERVOLTAGE) CATEGORIES DEFINITIONS
IEC/EN61010-1: Safety requirements for electrical equipment for measurement, control
and laboratory use, Part 1: General requirements, gives a definition of measuring
category, usually called overvoltage category. § 6.7.4: Measuring circuits:
(OMISSIS)
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 in the building installation.
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 norm requires that the transient withstand capability of the
equipment is made known to the user

define the correct nature of system loads under test.
The type of data displayed is determined by the setting of the instrument in the Analyzer
Configuration mode (see §. 5.3). With reference to PV systems only, further in this manual, the
acronym MPPT (Multiple Power Point Tracker) shall indicate the characteristic of the DC/AC
converter (inverter), capable of maximizing the DC power which can be taken from the
photovoltaic field and the acronym PRp shall indicate the Performance Ratio evaluated through
active powers. See § 10.3 for further details.

5.2.3. Screen of photovoltaic systems with multi-MPPT inverter (only with MPP300)
For the sake of simplicity, further in this manual, the word “string” will be used, although
often the term “photovoltaic field” would be more correct. From the point of view of the
instrument, the management of a single string or of more parallel strings (photovoltaic
field) is identical.
The instrument SOLAR300N, used together with remote units SOLAR-02 and MPP300
(optional), allows testing PV systems characterized by inverters with 1 or more MPPTs
connected to the relevant PV fields (consisting in PV modules with the same direction and
inclination) and single-phase or three-phase output.
The remote unit MPP300 communicates with SOLAR300N (to manage data setting,
synchronization and download) through the USB connection cable and with the remote
unit SOLAR-02 (for recording irradiation and temperature values) via a wireless
radiofrequency (RF) connection, which is active up to a maximum distance of 1m between
the units.
For further details on the use of MPP300, please see the unit’s user manual.
