1. PRECAUTIONS AND SAFETY MEASURES
The instrument has been designed in compliance with directive IEC/EN61010-1 relevant to
electronic measuring instruments. Before and while carrying out measurements, observe
the following indications and read all notes preceded by the symbol with the utmost
attention
CAUTION
In case the instrument is used in a way different from the one described in this
user manual, this could result in a failure of the protections the instrument is
provided with
Do not carry out any voltage or current measurement in humid environments
Do not carry out any measurements in case gas, explosive materials or flammables are
present, or in dusty environments
Avoid contact with the circuit being measured if no measurements are being carried out
Avoid contact with exposed metal parts, with unused measuring probes, circuits, etc
Do not carry out any measurement in case you find anomalies in the instrument such as
deformation, breaks, substance leaks, absence of display on the screen, etc
Pay special attention when measuring voltages higher than 20V, since a risk of
electrical shock exists
Only use original accessories
In this manual, and on the instrument, the following symbols are used:
CAUTION: observe the instructions given in this manual; an improper use could
damage the instrument or its components
High voltage danger: electrical shock hazard
Double insulation
DC voltage or current
AC voltage or current
Connection to earth
1.1. PRELIMINARY INSTRUCTIONS
This instrument has been designed for use in an environment with pollution level 2 and
in the environmental conditions specified in § 8.4. Do not use in different environmental
conditions
We recommend following the normal safety rules devised to protect the user from
dangerous currents and the instrument from an incorrect use
The instrument may be used for measuring VOLTAGE in CAT III 1000V DC or CAT IV
300V AC to earth. Do not use on systems exceeding the limit values specified in § 8
The instrument may be used for measuring CURRENT by means of external clamp
transducers
Only original HT accessories guarantee safety standards. They must be in good
conditions and replaced with identical models, when necessary
Before connecting the measuring cables to the circuit being measured, check that the
instrument has been correctly set

1.2. DURING USE
Please carefully read the following recommendations and instructions:
CAUTION
Failure to comply with the notes and/or instructions may damage the
instrument and/or its components or be a source of danger for the
operator
The red flashing “POWER” LED indicates that the internal rechargeable
batteries are almost flat. In this case, connect the external power supply
as described in § 7.2
The IDC1, IDC2, IDC3 input connectors are type 4-pole type. Use only
clamps with 4-pin output connector or interpose adapter ACON3F4M
between the clamp output connector and the instrument input.
The instrument maintains the data stored also in case of flat battery
The instrument is particularly sensitive to ESD nearby and on the USB
port while it is operating; we recommend connecting the cables to the USB
port when the instrument is off
1.3. AFTER USE
When measurements are completed, 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, please
follow the instructions given in § 3.4
1.4. 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 on installations 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

2. GENERAL DESCRIPTION
2.1. INTRODUCTION
Dear Customer, thank you for choosing one of the instruments in our range. If used
according to the instructions given in this manual, the instrument you have just purchased
will guarantee accurate and reliable measures. The instrument is designed to guarantee
maximum safety, thanks to a newly conceived development, which ensures double
insulation and enables the instrument to reach overvoltage category CAT III 1000V DC
and CAT IV 300V AC (to earth)
The instrument has been designed as an accessory for an instrument, hereafter called the
MASTER instrument (see par. 4.3), for the purpose of carrying out testing operations on
single-phase and three-phase PV systems.
Together with a MASTER instrument, MPP300 is the ideal solution for testing and
analyzing the possible problems linked to possible low efficiency values of photovoltaic
systems
2.2. INSTRUMENT FUNCTIONS
The instrument has the following features:
Measurement of 3 DC voltages and currents
Measurement of DC string power and total DC power
Measurement of 3 AC TRMS voltages and currents
Measurement of total AC power
Measurement of irradiation [W/m2] by means of a reference cell connected to unit
SOLAR-02
Measurement of panel and environmental temperature by means of probe PT300N
connected to SOLAR-02
Testing of PV systems with single/multi-MPPT inverter - single/three-phase AC output
Parameter recording of a PV system with 5s to 60min programmable IP
Internal memory for data saving
RF/USB interface for transferring the data to the MASTER instrument

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 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
§ 8.5. In case of discrepancy, please contact the Dealer. In case the instrument should be
returned, please follow the instructions given in § 10.
3.2. INSTRUMENT POWER SUPPLY
The instrument only operates with a Li-ION rechargeable battery (3.7V, 1900mAh) housed
inside the instrument itself. Use the external power supply A0055 provided to recharge the
battery. For indications on the status of the battery, please refer to § 7.2
The instrument maintains the data stored also in case of completely flat battery.
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
the environmental specifications contained in § 8.4).
