CAUTION
•The remote unit SOLAR-02 is a measuring instrument capable of using
radio frequency for data transfer. For internal reasons it was been
adopted a 2.4GHz harmonized frequency band. The above said radio
based device is built under Class 1 according to the Agreement
stipulated among EEC and EFTA countries, as defined by ERC/REC
70-03 protocols
•About a WiFi portable devices the European standards dictate
maximum radiated transmit power of 100mW EIRP and frequency
range 2.400 ÷2.4835GHz. In France these types of equipment must be
restricted to the 2.4465 ÷2.4835GHz frequency range and must be
restricted to indoor use

2. PRECAUTIONS AND SAFETY MEASURES
The instrument was designed in compliance with the requirements of R&TTE Directive as
well as of harmonized directives for electronic measuring instruments. Before and during
measurements, carefully observe the following instructions:
•Do not perform any measurement in humid environments, in the presence of gas or
explosive or inflammable material or in dusty areas.
•Avoid any contact with the circuit to be tested if no measurements are being carried
out.
•Avoid any contact with exposed metal parts, with unused measuring leads, circuits, etc.
•Do not perform any measurement when anomalies are found in the instrument, such as
deformations, breaks, substance leaks, no display view, etc.
•Only use HT original accessories.
In this manual, the following symbol is used:
CAUTION

2.2. DURING USE
We recommend carefully reading the following recommendations and instructions:
2.3. 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, remove
the batteries and follow the instructions given in § 7.3
3. PREPARATION FOR USE
3.1. INITIAL INSPECTIONS
Before shipment, the instrument’s electronics and mechanics have been inspected. All
possible precautions have been taken in order for the instrument to be delivered without
damage. However, we recommend generally inspecting the instrument in order to detect
any damage suffered during transport. Should you detect any anomalies, immediately
contact the forwarding agent. Moreover, we recommend checking that the package
contains all parts listed in § 0. Should you find any discrepancy, please contact the dealer.
Should it become necessary to return the instrument, please follow the instructions
reported in § 8
3.2. POWER SUPPLY
The instrument is supplied by 4 x 1,5V batteries type IEC LR03 AAA. When batteries are
almost flat, the symbol “ ” appears on the display. To replace the batteries, see § 6.2
CAUTION
The RF connection of remote unit SOLAR-02 is normally disabled for
default. For use of this unit with the Master meter “M-RF” (see Table
1) is necessary to activate the RF connection (see § 5.6.1)
CAUTION
•Failure to observe the warnings and/or instructions may damage the
instrument and/or its components or generate a danger for the operator.
•The symbol “ ” indicates that the batteries are flat. Stop testing and
replace the batteries according to the procedure described in § 6.2
•When the instrument is connected to the circuit being tested, never touch
any lead, even if unused.

5. USING THE REMOTE UNIT SOLAR-02
5.1. GENERAL
The remote unit SOLAR-02 can be used in the following modes:
1. Independent operation without connection to any master instrument for measuring in
real time the values of irradiation, cell temperature and environmental temperature on
PV installations. To this purpose, the unit accepts, as inputs:
For irradiation measurement (expressed in W/m2- PYRA/CELL input):
➢Solarimeter probe with thermobattery type Irr-P (see Table 1)
➢Double reference silicon cell type Irr-S2 (see Table 1)
For module and environmental temperature measurement (expressed in °C – TEMP
input)
➢Temperature probe type Tmp (see Table 1)
2. Operation for testing/recording synchronized with a master instrument for measuring
and saving irradiation and temperature values of cells and environment. The type of
connection with the master instruments is the following:
➢Connection via USB cable C2007 Master instrument type M-USB (see Tab l e 1)
➢Connection with radio frequency (RF) Master instrument type M-RF (see Tab l e 1)
According with settings receveid by MASTER instrument, SOLAR-02 display a Tc value:
➢Measured by the temperature probe “Tmp” (see Table 1)
➢Calcuted using NOCT (set in MASTER instrument), Irradiance and Environment
Temperature measured by SOLAR-02 according to relationship
where:
Tenv= Environment Temperature
Gp= Irradiance measured
NOCT= Normal Operating Cell Temperature
1. Press the /ESC key to turn on the instrument
2. After the initial screen, where all display symbols appear,
the screen beside, relevant to the loaded firmware version
(FW, e.g. 4.01), is displayed by the unit for a few seconds
3. The screen beside is displayed in order to show that no
probe is connected. From this moment on it is possible to
use the unit
4. Press and hold the /ESC key for a few seconds to turn
off the unit

5.2. PROGRAMMING THE REMOTE UNIT SOLAR-02
In order to obtain correct irradiation measurement results, it is necessary to carry out a
correct preliminary setting of the sensitivity values of the probes connected to the PYRA/
CELL input of the unit. The set values will be read and considered by the master
instruments upon testing/recording and will be kept by the SOLAR-02 even when the unit
is turned off, until they are modified.
The unit SOLAR-02 allows setting the parameters of max 3 irradiation sensors. In detail:
➢The use of a sensor type Irr-S2 requires setting the sensitivity (K) expressed in mV/
kW*m-2 or in µV/W*m-2 and the parameter Alpha expressed in %/°C for the various types of
silicon (monocrystalline, polycristalline, etc.)
➢The use of a sensor type Irr-P requires setting the sensitivity (K) expressed in mV/
kW*m-2 or in µV/W*m-2. The parameter Alpha expressed in %/°C is ignored.
The presence of “K” symbol on the left of “Tc” temperature value,
indicates that the Cell temperature (Tc) value displayed is not a measured
value buti s a calculated value according with previous relationship.
When the SOLAR-02 is switched on (before connection to MASTER
instrument) the Tc value is the measured value.
