IRR2-BT
Solar Irradiance Meter Pro
Users Manual
Introduction
The Fluke IRR2-BT Solar Irradiance Meter Pro (the Meter or
Product) provides digital measurements related to photovoltaic
(PV) panels.
The Meter measures and reads:
Solar irradiation (W/m2) on the surface of a photovoltaic (PV)
panel
Temperature (°F or °C) on the surface of a photovoltaic (PV)
panel
Inclination (degrees) of a photovoltaic (PV) panel
Cardinal degrees with the compass function
The Meter can wirelessly transfer measurements to the
SMFT-1000 PV Analyzer (the Analyzer). This data is used for
IV curve performance analysis of the solar panel and other
measurements of the roof slope and the compass.
Note
The Meter does not connect to smart phones and other
smart devices.
When the date and time on the Meter and the Analyzer match and
the Meter is out of wireless connection range with the Analyzer,
the Meter automatically records the data to memory. This data
can be transferred later to the SMFT-1000.

Operation
Use the Analyzer to adjust the recording settings, memory, and
clock synchronization. See SMFT-1000 Users Manual for more
information.
1. Power ON/OFF
At power on, the Meter shows the available memory in hours
for 2 seconds. The total memory capacity allows continuous
recording for 17 hours. Partial memory records for less time.
The display shows the Irradiance/Temperature mode
2 seconds after power up.
2. Move the Meter within wireless range of the main Analyzer.
The range is up to 50 m (150 ft) with a clear line-of-sight view
(no sight obstruction).
shows on the display when the Meter has wireless
connection to the Analyzer.
Note
If already installed on the roof, it is not necessary to
move the Meter. Instead, move the Analyzer near the
building to establish the connection. When connection is
established, you can synchronize both units from the
ground.
3. When connected, the Analyzer sends the command to the
Meter for synchronization, shows on the display.
5
The Meter automatically starts recording the irradiance and
temperature data and REC shows on the display until the
memory is full.
When the Meter is not synced, blinks on the display and
REC turns off.
should not blink at any point. For more information about
wireless connection, see the SMFT-1000 Users Manual.
When the memory on the Meter is full:
REC is off
turns ON
blinks on the display to indicate that the data cannot
download to the Analyzer

Irradiance and Internal Sensor Temperature
Measurements
To measure irradiance and temperature, install the Meter and the
bracket on the solar panel.
Note
For a spot check measurement, position the Meter
directly on the PV panel. The internal, embedded
conductive sensor in the back of the Meter automatically
takes the temperature reading.
The external temperature probe also takes temperature
measurements.
8
External Temperature Probe Connection
Connect the temperature probe to the top of the Meter. The
screen automatically shows when connected. The icon
indicates that the temperature is now read by the external probe.
Place the Meter on or beside the PV panel and connect the
temperature probe with the suction cup to the underside of the
PV panel. Secure the temperature probe to the panel with
electrical tape.
9
Inclination and Cardinal Direction
Place the Meter directly onto the PV panel to get accurate tilt. For
surfaces of rooftops with inclinations different than 0°, push
for 2 seconds to reset the angle and measure the true inclination
of a solar panel. Secure a probe to the solar panel with optional
electrical or similar tape to assure reliable mounting.
The compass measurement requires a two-step process for
accurate cardinal direction.
1. Do irradiance, temperature, and inclination measurements with
Meter placed on and aligned with the PV panel. The compass
function shows --- on the LCD when the tilt angle is above
20 degrees. At a tilt angle of >20 degrees any compass
reading shown will be inaccurate due to the influence by
surrounding metal objects.
2. Do the compass measurement away from the PV panel by
holding the meter or placing meter on a horizontal surface
(0 degrees to 20 degrees tilt) pointing the tip of the meter in
the direction that the PV panel faces. Keep away from any
metal objects.
Note
The compass measurement is in reference to magnetic
north. The measurement is unreliable if the Meter is
placed on or near objects containing metal (such as solar
panels, metal roofs, and concrete surfaces with rebar).

Compass Calibration
The Product contains a compass. The compass is affected by
metal in the environment.
Always recalibrate the compass:
Before the first use.
Each time you change the batteries.
When you change geographical locations.
When there is a significant change in the environment, for
example, new metal fittings.
1. Do the calibration outdoors, at least 2 m (6 ft) away from any
metal objects.
2. Push and hold the Switch button as you power on the Product
to enter compass calibration mode. The Product shows CAL
and the compass icon.
